在使用充电器对农业植保机的电池进行充电时,由于农业植保机所处环境湿度通常较大,故对充电器和电池之间的连接要求非常高。在通过充电器对电池充电时,需要将电池与充电器的电池正极连接端和电池负极连接端插接连接。若电池与电池正极连接端和电池负极连接端连接不到位,会导致电池不能正常充电等;并且由于连接不到位,导致电池与电池正极连接端和电池负极连接端之间的接触面积过小,这会引发充电器大量发热而烧毁,给用户造成损失。When using the charger to charge the battery of the agricultural plant protection machine, since the environmental humidity of the agricultural plant protection machine is usually relatively large, the connection between the charger and the battery is very high. When charging the battery through the charger, the battery needs to be plugged and connected to the battery positive terminal and the battery negative terminal of the charger. If the battery is not properly connected to the battery's positive terminal and the battery's negative terminal, it will cause the battery to fail to charge properly; and because the connection is not in place, the contact area between the battery and the battery's positive terminal and the battery's negative terminal will be too small. This will cause the charger to heat up a lot and burn, causing losses to users.

In another embodiment, the controller 3 obtains the charging voltage and charging current of the battery 300 to be charged through the first communication interface 12. Of course, the parameter information of the battery to be charged 300 acquired by the controller 3 through the first communication interface 12 may also include other parameter information of the battery to be charged 300, such as the real-time voltage of the battery to be charged 300.

The second communication interface 22 may also be an RS-485 interface or an RS-232 interface, and may also be another type of communication interface.
其中,功率信号可包括充电电压和/或充电电流,在一实施例中,当前连接在电池接口1上的待充电电池300需要恒压恒流充电,大功率电源模块100输出当前连接在电池接口1上的待充电电池300对应的充电电压和充电电流。在另一些实施例中,当前连接在电池接口1上的待充电电池300需要恒流充电,大功率电源模块100输出与当前连接在电池接口1上的待充电电池300对应的充电电流。通过控制大功率电源模块100的输出电流,实现电池快充、慢充的可选择性。The power signal may include a charging voltage and / or a charging current. In an embodiment, the battery 300 to be charged currently connected to the battery interface 1 needs constant voltage and constant current charging, and the high-power power module 100 outputs the current connection to the battery interface The charging voltage and charging current corresponding to the battery 300 to be charged on 1. In other embodiments, the battery 300 to be charged currently connected to the battery interface 1 needs constant current charging, and the high-power power supply module 100 outputs a charging current corresponding to the battery 300 to be charged currently connected to the battery interface 1. By controlling the output current of the high-power power supply module 100, the selectivity of fast charging and slow charging of the battery is realized.
需要说明的是,本发明实施例中,如无特别说明,充电电压是指额定电压,充电电流是指额定电流,在额定充电电压和/或额定充电电流下,待充电电池300的充电时间最短且安全性最好。本实施例通过大功率电源模块100输出与当前连接在充电接口上的待充电电池300对应的额定电压和/或额定电流,加快了电池的充电速度。It should be noted that, in the embodiments of the present invention, unless otherwise specified, the charging voltage refers to the rated voltage, and the charging current refers to the rated current. At the rated charging voltage and / or the rated charging current, the charging time of the battery 300 to be charged is the shortest And the best security. In this embodiment, the high-power power module 100 outputs the rated voltage and / or rated current corresponding to the battery 300 to be charged currently connected to the charging interface, thereby accelerating the charging speed of the battery.
而一些实施例中,充电电压也可小于额定电压,充电电流小于额定电流,以确 保充电安全性,例如,充电器200具备预充电功能,当电池处于欠压保护时,充电器200会输出小于额定电流的电流对电池预充电,直到电池电压恢复正常,再用额定电流对电池充电。具体的,控制器3在根据当前待充电电池300(即当前连接在充电接口上的待充电电池300)的参数信息判断出当前待充电电池300的电压小于安全充电电压时,通过第二通信接口22发送预充电请求至大功率电源模块100,以触发大功率电源模块100输出第一功率信号,其中,第一功率信号小于预设功率阈值。本实施例中,当前待充电电池300的安全充电电压为当前待充电电池300的额定电压,预设功率阈值≤当前待充电电池300的额定电压乘以当前待充电电池300的额定电流。可选的,控制器3通过第二通信接口22发送预充电请求至大功率电源模块100,触发大功率电源模块100输出最小的电流,对当前待充电电池300进行涓流充电。In some embodiments, the charging voltage may also be less than the rated voltage, and the charging current is less than the rated current to ensure the safety of charging. For example, the charger 200 has a pre-charging function. When the battery is under-voltage protection, the charger 200 will output less than The current of the rated current pre-charges the battery until the battery voltage returns to normal, and then charges the battery with the rated current. Specifically, when the controller 3 determines that the voltage of the current battery 300 to be charged is less than the safe charging voltage according to the parameter information of the current battery 300 to be charged (that is, the battery 300 to be connected to the charging interface), the controller 3 uses the second communication interface 22 Send a pre-charge request to the high-power power module 100 to trigger the high-power power module 100 to output a first power signal, where the first power signal is less than a preset power threshold. In this embodiment, the current safe charging voltage of the battery 300 to be charged is the rated voltage of the battery 300 to be charged, and the preset power threshold ≤ the rated voltage of the current battery 300 to be multiplied by the rated current of the battery 300 to be charged. Optionally, the controller 3 sends a pre-charge request to the high-power power module 100 through the second communication interface 22 to trigger the high-power power module 100 to output a minimum current to trickle charge the current battery 300 to be charged.
进一步的,在通过第一功率信号对当前待充电电池300充电的过程中,控制器3通过第一通信接口12获取当前待充电电池300的实时电压;控制器3在判断出实时电压与安全充电电压的差值小于预设差值阈值时,通过第二通信接口22发送充电触发信号至大功率电源模块100,以触发大功率电源模块100输出当前待充电电池300对应的功率信号,其中,第一功率信号小于当前待充电电池300对应的功率信号。本实施例中,控制器3在判断出实时电压接近或者大大安全充电电压时,通过第二通信接口22发送充电触发信号至大功率电源模块100,对当前待充电电池300进行快速充电。Further, in the process of charging the current battery 300 to be charged through the first power signal, the controller 3 obtains the real-time voltage of the current battery 300 to be charged through the first communication interface 12; the controller 3 determines the real-time voltage and safe charging When the voltage difference is less than the preset difference threshold, a charging trigger signal is sent to the high-power power module 100 through the second communication interface 22 to trigger the high-power power module 100 to output the current power signal corresponding to the battery 300 to be charged. A power signal is smaller than the current power signal corresponding to the battery 300 to be charged. In this embodiment, the controller 3 sends a charging trigger signal to the high-power power module 100 through the second communication interface 22 when it determines that the real-time voltage is close to or greatly safe to charge the voltage, and quickly charges the current battery 300 to be charged.
本实施例中,可采用不同的方式触发大功率电源模块100输出与待充电电池300对应的功率信号,比如,在一实施例中,触发信号直接携带有待充电电池300的参数信息,大功率电源模块100根据接收到的触发信号中的待充电电池300的参数信息,输出与该待充电电池300对应的功率信号。可选的,触发信号携带有待充电电池300的充电电压和/或待充电电池300的充电电流,大功率电源模块100在接收到该触发信号后,输出对应的电压值和/或电流值。当控制器3通过第一通信接口12获取的待充电电池300的参数信息为待充电电池300的充电电压和/或待充电电池300的充电电流时,控制器3直接根据待充电电池300的充电电压和/或待充电电池300的充电电流,产生充电触发信号。当控制器3通过第一通信接口12获取的待充电电池300的参数信息为待充电电池300的类型时,控制器3根据待充电电池300的类型,从预设数据库中获取待充电电池300的充电电压和/或待充电电池300的充电电流,再根据待充电电池300的充电电压和/或待充电电池300的充电电流,产生充电触发信号。可选的,触发信号携带有待充电电池300的类型,大功率电源模块100在接收到该触发信号后,从预设数据库中获取到该类型的电池的充电电压和/或充电电流,并输出对应的电压值和/或电流值。上述实施例中,预设数据库保存有各电池类型及各电池类型对应的充电电压和/或充电电流。In this embodiment, different methods can be used to trigger the high-power power supply module 100 to output a power signal corresponding to the battery 300 to be charged. For example, in one embodiment, the trigger signal directly carries the parameter information of the battery 300 to be charged, the high-power power supply The module 100 outputs a power signal corresponding to the battery 300 to be charged according to the parameter information of the battery 300 to be charged in the received trigger signal. Optionally, the trigger signal carries the charging voltage of the battery 300 to be charged and / or the charging current of the battery 300 to be charged. After receiving the trigger signal, the high-power power module 100 outputs the corresponding voltage value and / or current value. When the parameter information of the battery to be charged 300 obtained by the controller 3 through the first communication interface 12 is the charging voltage of the battery to be charged 300 and / or the charging current of the battery to be charged 300, the controller 3 directly according to the charging of the battery to be charged 300 The voltage and / or the charging current of the battery 300 to be charged generate a charging trigger signal. When the parameter information of the battery to be charged 300 acquired by the controller 3 through the first communication interface 12 is the type of the battery to be charged 300, the controller 3 obtains the battery 300 to be charged from the preset database according to the type of the battery to be charged 300 The charging voltage and / or the charging current of the battery 300 to be charged, and then generating a charging trigger signal according to the charging voltage of the battery 300 to be charged and / or the charging current of the battery 300 to be charged. Optionally, the trigger signal carries the type of the battery 300 to be charged. After receiving the trigger signal, the high-power power supply module 100 obtains the charging voltage and / or charging current of the battery of this type from a preset database and outputs the corresponding Voltage value and / or current value. In the above embodiment, the preset database stores each battery type and the charging voltage and / or charging current corresponding to each battery type.
在另一实施例中,待充电电池300的参数信息不同,控制器3产生的触发信号则不同,例如,对于类型不同的电池A和电池B,当控制器3通过第一通信接口12 获取到的待充电电池300的参数信息为电池A的类型时,产生第一触发信号;而当控制器3通过第一通信接口12获取到的待充电电池300的参数信号为电池A的类型时,产生第二触发信号。大功率电源模块100在接收到第一触发信号时,输出电池A对应的功率信号;大功率电源模块100在接收到第二触发信号时,输出电池B对应的功率信号。In another embodiment, the parameter information of the battery 300 to be charged is different, and the trigger signal generated by the controller 3 is different. For example, for the battery A and the battery B of different types, when the controller 3 obtains it through the first communication interface 12 When the parameter information of the battery 300 to be charged is the type of the battery A, a first trigger signal is generated; and when the parameter signal of the battery 300 to be charged obtained by the controller 3 through the first communication interface 12 is the type of the battery A, it is generated The second trigger signal.

第二种,充电器200还包括定位模块,如GPS模块,该定位模块用于检测充电器200的当前位置,并且定位模块与控制器3电耦合连接,控制器3根据充电器200的当前位置确定充电器200当前电耦合连接的市电电源的电压大小。不同的国家电网电压为固定值,充电器200在通过定位模块检测到充电器200的当前位置后,即可根据当前位置确定充电器200当前电耦合连接的市电电源的电压大小。Secondly, the charger 200 further includes a positioning module, such as a GPS module, which is used to detect the current position of the charger 200, and the positioning module is electrically coupled to the controller 3, and the controller 3 according to the current position of the charger 200 Determine the voltage level of the mains power supply to which the charger 200 is currently electrically coupled. The voltage of different national grids is a fixed value. After detecting the current position of the charger 200 through the positioning module, the charger 200 can determine the voltage level of the mains power supply currently electrically coupled to the charger 200 according to the current position.
本实施例的充电器200在检测到其与大功率电压模块通信不良时,关闭大功率电压模块的输出,提高充电可靠性。可选的,当待充电电池300与电池接口1相连接时,控制器3在检测到第二通信接口22与大功率电源模块100之间间歇通信,发送充电停止信号至大功率电源模块100,使得大功率电源模块100停止输出功率信号。正常情况下,在待充电电池300与电池接口1相连接时,若第二通信接口22与大功率电源模块100连接,充电器200会通过第二通信接口22与大功率电源模块100持续通信。当第二通信接口22与大功率电源模块100由于连接松动或者其他原因导致两者接触不良时,控制器3会检测到第二通信接口22与大功率电源模块100之间通信时断时续,当控制器3检测到第二通信接口22与大功率电源模块100之间通信时断时续的时长超过特定时长(如5秒)时,则发送充电停止信号至大功率电源模块100,关断大功率电源模块100的输出,提高充电可靠性。When detecting that the communication with the high-power voltage module is poor, the charger 200 of this embodiment turns off the output of the high-power voltage module to improve charging reliability. Optionally, when the battery to be charged 300 is connected to the battery interface 1, the controller 3 detects intermittent communication between the second communication interface 22 and the high-power power module 100, and sends a charging stop signal to the high-power power module 100, This causes the high-power power module 100 to stop outputting power signals. Normally, when the battery to be charged 300 is connected to the battery interface 1, if the second communication interface 22 is connected to the high-power power module 100, the charger 200 will continue to communicate with the high-power power module 100 through the second communication interface 22. When the connection between the second communication interface 22 and the high-power power module 100 is poor due to loose connections or other reasons, the controller 3 will detect that the communication between the second communication interface 22 and the high-power power module 100 is intermittent, When the controller 3 detects that the intermittent communication time between the second communication interface 22 and the high-power power module 100 exceeds a specific time period (such as 5 seconds), it sends a charging stop signal to the high-power power module 100 to turn off The output of the high-power power module 100 improves the charging reliability.
可选的,当待充电电池300与电池接口1相连接时,控制器3检测到电源输入接口21间歇接收到功率信号时,发送充电停止信号至大功率电源模块100,使得大功率电源模块100停止输出功率信号。在待充电电池300与电池接口1相连接时,若电源输入接口21与大功率电源模块100连接,控制器3在触发大功率电源模块100输出与当前待充电电池300对应的功率信号后,电源输入接口21会持续接收到该功率信号。 当电源输入接口21与大功率电源模块100由于连接松动或者其他原因导致两者接触不良时,控制器3会检测到电源输入接口21时断时续地接收到功率信号,当控制器3检测到电源输入接口21时断时续地接收到功率信号超过特定时长(如5秒)时,则发送充电停止信号至大功率电源模块100,关断大功率电源模块100的输出,提高充电可靠性。Optionally, when the battery to be charged 300 is connected to the battery interface 1, the controller 3 detects that the power input interface 21 receives the power signal intermittently, and sends a charging stop signal to the high-power power module 100, so that the high-power power module 100 Stop outputting power signal. When the battery to be recharged 300 is connected to the battery interface 1, if the power input interface 21 is connected to the high-power power module 100, the controller 3 triggers the high-power power module 100 to output a power signal corresponding to the current battery 300 to be recharged. The input interface 21 will continue to receive the power signal. When the power input interface 21 and the high-power power module 100 are loosely connected due to loose connections or other reasons, the controller 3 will detect that the power input interface 21 intermittently receives a power signal, and when the controller 3 detects When the power input interface 21 receives the power signal intermittently for more than a certain period of time (such as 5 seconds), it sends a charging stop signal to the high-power power module 100 to turn off the output of the high-power power module 100 to improve charging reliability.
进一步的,本实施例的充电器200还增加了不良日志记录功能,用户在使用充电器200的过程中有任何不良,充电器200会自动存储信息,方便后续分析统计,为提高以后产品质量打好基础。例如,控制器3在检测到第二通信接口22与大功率电源模块100之间间歇通信,或者检测到电源输入接口21间歇接收到功率信号时,生成不良日志并保存。本实施例的充电器200可包括SD卡或其他存储单元,控制器3将生成的不良日志保存在SD卡或其他存储单元中。Further, the charger 200 of this embodiment also adds a defect logging function. If the user has any defects in the process of using the charger 200, the charger 200 will automatically store information to facilitate subsequent analysis and statistics, in order to improve future product quality. Good foundation. For example, when the controller 3 detects intermittent communication between the second communication interface 22 and the high-power power module 100, or detects that the power input interface 21 intermittently receives a power signal, it generates a bad log and saves it. The charger 200 of this embodiment may include an SD card or other storage unit, and the controller 3 saves the generated bad log in the SD card or other storage unit.
此外,本实施例的充电器200还可包括风扇,该风扇与控制器3电耦合连接。控制器3在确定风扇堵转时,发送控制信号至大功率电源模块100,以控制大功率电源模块100减小当前输出的功率信号中的充电电流大小。具体的,控制器3与风扇电机电耦合连接,控制器3通过检测风扇电机是否堵转来确定风扇是否堵转,当控制器3检测到风扇电机堵转时,则确定风扇堵转;否则,确定风扇不堵转。其中,风扇电机是否堵转的检测方式为现有技术,此处不再展开讨论。本实施例的风扇被堵转时,控制器3不会控制大功率电源模块100关闭其输出,而是控制大功率电源模块100减小其输出的电流值,保证充电不中断,可保证即使处于复杂的外界环境,充电器200也能保持安全工作。在充电器200中,风扇的作用和诸如笔记本等设备中风扇有所不同,对于笔记本等设备的CPU、显卡等芯片本身承担核心算力,功耗很大,所以发热量很大,如果风扇停转,芯片有烧毁的风险。而充电器200属于换能器件,功耗小发射热量也不大,即使风扇停转,在小电流充电场景下不会发生器件上的损坏,故无需关闭大功率电源模块100。In addition, the charger 200 of this embodiment may further include a fan, which is electrically coupled to the controller 3. When it is determined that the fan is locked, the controller 3 sends a control signal to the high-power power module 100 to control the high-power power module 100 to reduce the charging current in the currently output power signal. Specifically, the controller 3 is electrically coupled to the fan motor. The controller 3 determines whether the fan is blocked by detecting whether the fan motor is blocked. When the controller 3 detects that the fan motor is blocked, it determines that the fan is blocked; otherwise, Make sure the fan is not blocked. Among them, the detection method of whether the fan motor is blocked is the prior art, and will not be discussed here. When the fan of this embodiment is blocked, the controller 3 does not control the high-power power module 100 to turn off its output, but controls the high-power power module 100 to reduce the current value of its output, to ensure that the charging is not interrupted, and even In a complicated external environment, the charger 200 can also keep working safely. In the charger 200, the role of the fan is different from the fan in devices such as notebooks. For notebooks and other devices, the CPU, graphics card and other chips themselves bear the core computing power, and the power consumption is very large, so the heat is very large. If the fan stops In turn, the chip is at risk of burning. The charger 200 belongs to a transducing device, and the heat emission is not large even if the power consumption is small. Even if the fan stops, damage to the device will not occur in the small current charging scenario, so there is no need to turn off the high-power power module 100.
进一步的,本实施例的充电器200还可包括温度传感器,该温度传感器用于检测环境温度,并且温度传感器与控制器3电耦合连接。本实施例的控制器3在判断出环境温度大于预设温度阈值,并且功率信号中的充电电流小于预设电流阈值时,关闭风扇。控制器3在环境温度高、充电电流小的情况下,将风扇关闭,避免环境温度高但没有使用的待机情况下启动风扇,从而延长风扇寿命。Further, the charger 200 of this embodiment may further include a temperature sensor, which is used to detect the ambient temperature, and the temperature sensor is electrically coupled to the controller 3. The controller 3 of this embodiment turns off the fan when it determines that the ambient temperature is greater than the preset temperature threshold and the charging current in the power signal is less than the preset current threshold. The controller 3 turns off the fan when the ambient temperature is high and the charging current is small, to avoid starting the fan in a standby environment where the ambient temperature is high but not in use, thereby extending the life of the fan.
预设温度阈值可根据需要设定,如可将预设温度阈值设定为50℃(单位:摄氏度)或者其他,以满足充电器200的高温保护功能。相应的,预设电流阈值也可根据需要设定,如可将预设电流阈值设定为1mA(单位:毫安),以判断充电器200是否处于待机。The preset temperature threshold may be set according to needs. For example, the preset temperature threshold may be set to 50 ° C (unit: degree Celsius) or other to meet the high-temperature protection function of the charger 200. Correspondingly, the preset current threshold can also be set as needed. For example, the preset current threshold can be set to 1 mA (unit: milliampere) to determine whether the charger 200 is in standby.
在一实施例中,充电器200具有多路输出管理功能,充电器200通过与多个待 充电电池300通信,管理多个电池同时充电,实现多通道输出。具体的,电池接口1包括多个,第一开关模块4也包括多个,如图7所示,充电接口和第一开关模块4分别为两个。在本实施例中,每个电池接口1的电源输出接口11经对应的第一开关模块4电耦合连接至电源输入接口21。In one embodiment, the charger 200 has a multi-output management function. The charger 200 manages the simultaneous charging of a plurality of batteries by communicating with a plurality of batteries 300 to be charged to achieve multi-channel output. Specifically, the battery interface 1 includes a plurality, and the first switch module 4 also includes a plurality. As shown in FIG. 7, there are two charging interfaces and the first switch module 4 respectively. In this embodiment, the power output interface 11 of each battery interface 1 is electrically coupled to the power input interface 21 via the corresponding first switch module 4.
在本实施例中,当多个电池接口1中至少两个电池接口1分别连接有待充电电池300时,控制器3通过对应的第一通信接口12获取对应的待充电电池300的参数信息。并且,控制器3根据获取的至少两个待充电电池300的参数信息,生成充电触发信号。本实施例的充电触发信号携带有每一待充电电池300的充电顺序,每一待充电电池300的充电顺序用于指示大功率电源模块100输出与该待充电电池300对应的功率信号的顺序。接着,控制器3通过第二通信接口22发送充电触发信号至大功率电源模块100,以触发大功率电源模块100根据每一待充电电池300的充电顺序依次输出该待充电电池300的功率信号。并且,控制器3在大功率电源模块100输出该待充电电池300的功率信号时,控制对应的第一开关模块4开启,以将功率信号传输至该待充电电池300,从而实现对连接在充电器200上的多个待充电电池300依次充电,无需人工干预,提高充电效率。In this embodiment, when at least two battery interfaces 1 of the plurality of battery interfaces 1 are respectively connected to the battery 300 to be charged, the controller 3 obtains the parameter information of the corresponding battery 300 to be charged through the corresponding first communication interface 12. And, the controller 3 generates a charging trigger signal according to the acquired parameter information of at least two batteries to be charged 300. The charging trigger signal of this embodiment carries the charging sequence of each battery 300 to be charged, and the charging sequence of each battery 300 to be charged is used to instruct the order in which the high-power power module 100 outputs the power signal corresponding to the battery 300 to be charged. Next, the controller 3 sends a charging trigger signal to the high-power power module 100 through the second communication interface 22 to trigger the high-power power module 100 to sequentially output the power signal of the battery 300 to be charged according to the charging sequence of each battery 300 to be charged. Moreover, when the high-power power module 100 outputs the power signal of the battery 300 to be charged, the controller 3 controls the corresponding first switch module 4 to be turned on to transmit the power signal to the battery 300 to be charged, so as to realize the charging The plurality of to-be-charged batteries 300 on the charger 200 are sequentially charged without manual intervention, and the charging efficiency is improved.
在一实施例中,充电器200在同一时刻对一个待充电电池300进行充电,并在该待充电电池300充电结束后,对其他待充电电池300进行充电。具体而言,控制器3在同一时刻控制一个第一开关模块4开启,而保持其他第一开关模块4关闭,以确保充电器200在同一时刻对一个对待充电电池300充电的目的。In an embodiment, the charger 200 charges one battery 300 to be charged at the same time, and charges the other battery 300 to be charged after the charging of the battery 300 is completed. Specifically, the controller 3 controls one first switch module 4 to be turned on at the same time, while keeping other first switch modules 4 to be turned off, to ensure that the charger 200 charges one battery 300 to be charged at the same time.
在另一实施例中,为进一步提高充电效率,充电器200在同一时刻能够对同一类型的待充电电池进行充电,并在该类型的待充电电池电结束后,对其他类型的待充电电池进行充电。具体的,在大功率电源模块100输出该待充电电池300的功率信号时,若控制器3根据获取的至少两个待充电电池的参数信息,判断出其他待充电电池中存在与该待充电电池类型相同的待充电电池,则控制与该待充电电池类型相同的待充电电池的第一开关模块4开启,而将与该待充电电池类型相同的待充电电池和大功率电源模块100电耦合连接。In another embodiment, in order to further improve the charging efficiency, the charger 200 can charge the same type of battery to be charged at the same time, and after the end of the type of battery to be charged, to other types of batteries to be charged Charge. Specifically, when the high-power power module 100 outputs the power signal of the battery to be charged 300, if the controller 3 determines the existence of the battery to be charged among other batteries to be charged according to the acquired parameter information of at least two batteries to be charged For the same type of to-be-charged battery, the first switch module 4 of the same type of to-be-charged battery is controlled to be turned on, and the same type of to-be-charged battery of the same type as the to-be-charged battery and the high-power power supply module 100 are electrically coupled to each other .
每一待充电电池的充电顺序可根据需要设计,例如,在一实施例中,每一待充电电池的充电顺序为各待充电电池与电池接口1相连的先后顺序。进一步的,每一类型的待充电电池的充电顺序为各类型的待充电电池首次与电池接口1相连的先后顺序。例如,充电器200在同一时刻同时连接有2个待充电电池A和1个待充电电池B,2个待充电电池A和1个待充电电池B是按照待充电电池A->待充电电池B->待充电电池A的顺序依次连接在充电器200的3个电池接口1上的。对于2个待充电电池A,由于待充电电池A首次与电池接口1相连顺序早于待充电电池B,故充电器200先对2个待充电电池A进行充电(对2个待充电电池A同时充电或依次充电),在2个待充电电池A充电完毕后,充电器200再对待充电电池B进行充电。The charging sequence of each battery to be recharged can be designed according to needs. For example, in an embodiment, the charging sequence of each battery to be recharged is the sequence in which each battery to be recharged is connected to the battery interface 1. Further, the charging sequence of each type of battery to be charged is the order in which each type of battery to be charged is connected to the battery interface 1 for the first time. For example, the charger 200 is connected to two batteries A and one battery B to be charged at the same time, and two batteries A and one battery B are charged according to the battery A-> battery B to be charged -> The order of the battery A to be charged is connected to the three battery interfaces 1 of the charger 200 in sequence. For two batteries A to be recharged, the first time that the battery A is connected to the battery interface 1 is earlier than the battery B to be charged, so the charger 200 first charges the two batteries A to be charged (the two batteries A to be charged at the same time Charge or charge sequentially). After the two batteries A to be charged are completely charged, the charger 200 charges the battery B to be charged again.
在另一实施例中,控制器3根据获取的至少两个待充电电池的参数信息,判断出至少两个待充电电池包括多种类型电池。在本实施例中,至少两个待充电电池的充电顺序根据至少两个待充电电池的类型确定。进一步的,可根据不同的策略来根据至少两个待充电电池的类型确定至少两个待充电电池的充电顺序,例如,在一些例子中,至少两个待充电电池的充电顺序根据各类型的待充电电池的数量多少确定。可选的,至少两个待充电电池的充电顺序为各类型的待充电电池的数量从大至小的先后排序。例如,充电器200在同一时刻同时连接有2个待充电电池A和1个待充电电池B,连接在充电器200上的待充电电池A的数量>连接在充电器200上的待充电电池B的数量,故充电器200先对2个待充电电池A进行充电(对2个待充电电池A同时充电或依次充电),在2个待充电电池A充电完毕后,充电器200再对待充电电池B进行充电。在另一些例子中,至少两个待充电电池的充电顺序根据预设的各类型的待充电电池的充电优先级确定。例如,充电器200在同一时刻同时连接有2个待充电电池A和1个待充电电池B,待充电电池B的充电优先级大于待充电电池A的充电优先级,故充电器200先对待充电电池B进行充电,在待充电电池B进行充电完毕后,充电器200再对2个待充电电池A进行充电(对2个待充电电池A同时充电或依次充电)。In another embodiment, the controller 3 determines that the at least two batteries to be charged include multiple types of batteries based on the acquired parameter information of the at least two batteries to be charged. In this embodiment, the charging sequence of the at least two batteries to be charged is determined according to the types of the at least two batteries to be charged. Further, the charging sequence of at least two to-be-recharged batteries may be determined according to the types of at least two to-be-recharged batteries according to different strategies. For example, in some examples, the charging sequence of at least two to-be-recharged batteries is based on various types of to-be-charged batteries. The number of rechargeable batteries is determined. Optionally, the charging sequence of at least two to-be-charged batteries is that the number of to-be-charged batteries of various types is sorted in descending order. For example, the charger 200 is connected to two batteries A to be charged and one battery B to be charged at the same time, the number of batteries A to be connected to the charger 200> the battery B to be connected to the charger 200 Number, the charger 200 first charges the two batteries A to be charged (charging the two batteries A to be charged at the same time or sequentially), and after the two batteries A to be charged are charged, the charger 200 treats the batteries to be charged again B to charge. In other examples, the charging sequence of the at least two batteries to be charged is determined according to preset charging priorities of various types of batteries to be charged. For example, the charger 200 is connected to two batteries A and one battery B at the same time. The charging priority of the battery B is greater than the charging priority of the battery A, so the charger 200 treats the battery first. The battery B is charged, and after the charging of the battery B to be charged is completed, the charger 200 charges the two batteries A to be charged again (the two batteries A to be charged are simultaneously charged or sequentially charged).
值得一提的是,控制器3获取当前连接在电池接口1上的待充电电池300的参数信息的方式并不限于上述实施例中的通过第一通信接口12与待充电电池300通信的方式,也可采用其他方式来获取当前连接在电池接口1上的待充电电池300的参数信息。It is worth mentioning that the manner in which the controller 3 obtains the parameter information of the battery 300 to be charged currently connected to the battery interface 1 is not limited to the manner of communicating with the battery 300 to be charged through the first communication interface 12 in the above embodiment, The parameter information of the battery 300 to be charged currently connected to the battery interface 1 may also be obtained in other ways.
在一替换实施例中,如图8至图12所示,电池接口1仅包括电源输出接口11,而不包括第一通信接口12。本实施例的电源输出接口11包括电池正极连接端111和电池负极连接端112。参见图8,本实施例提供一种充电器200的充电控制电路,该充电控制电路包括控制器3以及采样电路6,可选的,充电控制电路的控制器3与上述实施例的控制器3为同一处理器;可选的,充电控制电路的控制器3与上述实施例的控制器3为两个独立处理器,充电控制电路的控制器3与上述实施例的控制器3通信连接。In an alternative embodiment, as shown in FIGS. 8-12, the battery interface 1 only includes the power output interface 11 and does not include the first communication interface 12. The power output interface 11 of this embodiment includes a battery positive terminal 111 and a battery negative terminal 112. Referring to FIG. 8, this embodiment provides a charging control circuit of a charger 200. The charging control circuit includes a controller 3 and a sampling circuit 6. Optionally, the controller 3 of the charging control circuit and the controller 3 of the above embodiment It is the same processor; optionally, the controller 3 of the charging control circuit and the controller 3 of the above embodiment are two independent processors, and the controller 3 of the charging control circuit is in communication connection with the controller 3 of the above embodiment.
其中,控制器3具有信号检测端,采样电路6具有信号输出端、第一信号输入端和第二信号输入端。信号输出端与信号检测端电耦合连接,第一信号输入端与电池正极连接端111电耦合连接,第二信号输入端与电池负极连接端112电耦合连接。The controller 3 has a signal detection terminal, and the sampling circuit 6 has a signal output terminal, a first signal input terminal, and a second signal input terminal. The signal output terminal is electrically coupled to the signal detection terminal, the first signal input terminal is electrically coupled to the battery positive terminal 111, and the second signal input terminal is electrically coupled to the battery negative terminal 112.
本实施例中,当电池接口1连接有待充电电池300时,待充电电池300的正极与电池正极连接端111相连,待充电电池300的负极与电池负极连接端112相连。第一信号输入端通过电池正极连接端111与待充电电池300的正极电耦合连接,第二信号输入端通过电池负极连接端112与待充电电池300的负极电耦合连接,信号输出端输出第一信号。控制器3在通过信号检测端检测到第一信号时,控制充电器200开启,以通过充电器200对待充电电池300充电。本实施例通过充电控制电路实现电池在位 侦测功能,当待充电电池300与电池接口1连接到位时,充电器200才会自动唤醒,提高了充电安全性。In this embodiment, when the battery interface 1 is connected to the battery 300 to be charged, the positive electrode of the battery to be charged 300 is connected to the positive electrode terminal 111 of the battery, and the negative electrode of the battery to be charged 300 is connected to the negative electrode terminal 112 of the battery. The first signal input terminal is electrically coupled to the positive electrode of the battery 300 to be charged through the battery positive terminal 111, the second signal input terminal is electrically coupled to the negative electrode of the battery 300 to be charged through the battery negative terminal 112, and the signal output terminal outputs the first signal. When the first signal is detected by the signal detection terminal, the controller 3 controls the charger 200 to be turned on to charge the battery 300 to be charged through the charger 200. In this embodiment, the battery in-position detection function is implemented by the charging control circuit. When the battery to be charged 300 is connected to the battery interface 1 in place, the charger 200 will automatically wake up, which improves the safety of charging.
进一步的,当电池接口1未连接有待充电电池300时,信号输出端输出第二信号,本实施例的第二信号与第一信号不同,控制器3在通过信号检测端检测到第二信号时,控制充电器200关闭。本实施例中,当电池接口1连接有待充电电池300时,充电器200自动唤醒。当电池接口1未连接待充电电池300时,充电器200处于空闲状态,充电器200无输出,从而降低充电器200待机功耗。Further, when the battery interface 1 is not connected to the battery 300 to be charged, the signal output terminal outputs a second signal. The second signal in this embodiment is different from the first signal. When the controller 3 detects the second signal through the signal detection terminal To control the charger 200 to turn off. In this embodiment, when the battery interface 1 is connected to the battery 300 to be charged, the charger 200 automatically wakes up. When the battery interface 1 is not connected to the battery 300 to be charged, the charger 200 is in an idle state, and the charger 200 has no output, thereby reducing the standby power consumption of the charger 200.
更进一步的,本实施例的充电器200通过同一充电控制电路能够实现对多种类型的待充电电池300的在位侦测,通用性强。具体的,当电池接口1与不同类型的待充电电池300连接时,信号输出端输出不同大小的第一信号。控制器3能够根据第一信号的大小,控制电池接口1的电源输出接口11输出与当前插接在充电器200上的待充电电池300相对应的功率信号,其中,不同类型的待充电电池300对应的功率信号不相同。本实施例中,控制器3能够根据第一信号的大小,确定当前插接在电池接口1上的待充电电池300的类型。表1为一具体实施例中充电接口状态与采样电路6的信号输出端输出的信号值之间的关系,控制器3即可根据采样电路6的信号输出端输出的信号值来确定充电接口的状态以及当前插接在充电接口上的待充电电池300的类型。Furthermore, the charger 200 of this embodiment can realize the presence detection of various types of batteries 300 to be charged through the same charging control circuit, and has strong versatility. Specifically, when the battery interface 1 is connected to a different type of battery 300 to be charged, the signal output terminal outputs first signals of different sizes. The controller 3 can control the power output interface 11 of the battery interface 1 to output a power signal corresponding to the battery 300 to be charged currently connected to the charger 200 according to the magnitude of the first signal, wherein different types of battery to be charged 300 The corresponding power signals are different. In this embodiment, the controller 3 can determine the type of the battery 300 to be charged currently connected to the battery interface 1 according to the magnitude of the first signal. Table 1 shows the relationship between the state of the charging interface and the signal value output from the signal output terminal of the sampling circuit 6 in a specific embodiment. The controller 3 can determine the charging interface according to the signal value output from the signal output terminal of the sampling circuit 6 The status and the type of battery 300 to be charged currently plugged into the charging interface.
