Description

电池充电方法、装置及计算机存储介质Battery charging method, device and computer storage medium 技术领域Technical field
本发明涉及电池技术领域,特别是涉及一种电池充电方法、装置及计算机存储介质。The present invention relates to the field of battery technologies, and in particular, to a battery charging method, apparatus, and computer storage medium.
背景技术Background technique
当今,锂离子电池由于其高能量密度、开路电压高、输出功率大、低自放电以及无记忆效应等特点被广泛应用于消费电子产品和电动助力设备上。Today, lithium-ion batteries are widely used in consumer electronics and electric power equipment due to their high energy density, high open circuit voltage, high output power, low self-discharge, and no memory effect.
目前由于环境保护的大力提倡,电能源由于其无污染性,也越来越得到各方面的关注,如今消费产品的电池容量已经达到3AH(Ampere-Hour,安培小时,衡量蓄电设备容量的单位,1AH表示该蓄电设备在供电电流强度为1A时持续工作1小时)以上,电动自行车电池容量单颗容量10AH,一般都用到40AH以上。电动车电池的容量一般都用到80AH以上,如此大的容量,想在短时间内充电完成,必需使用快速充电方案。快速充电目前主要的还是大电流充电,通常使用1C,甚至2C充电。C表示电池充放电时电流大小的比率,即倍率。如1200mAh的电池,0.2C表示240mA(1200mAh的0.2倍率),1C表示1200mA(1200mAh的1倍率)。大电流充电不可避免的导致电池寿命将会降低,有研究表明:使用2C充电的老化率是1C充电的1.63倍,并且随着电池的老化,老化率是不断上升的,故一直在恒流阶段使用相同的大电流充电,会加剧电池的老化,降低锂离子电池的使用寿命。 At present, due to the strong promotion of environmental protection, electric energy has become more and more concerned because of its non-polluting nature. Today, the battery capacity of consumer products has reached 3AH (Ampere-Hour, ampere-hour, unit for measuring the capacity of storage equipment). 1AH means that the power storage device continues to operate for 1 hour or more when the power supply current intensity is 1A. The electric bicycle battery capacity has a single capacity of 10AH, and generally uses 40AH or more. The capacity of electric vehicle batteries is generally more than 80AH. With such a large capacity, if you want to charge in a short time, you must use a fast charging solution. The main reason for fast charging is still high current charging, usually using 1C or even 2C charging. C represents the ratio of the magnitude of the current when the battery is charged and discharged, that is, the magnification. For example, a 1200 mAh battery, 0.2 C means 240 mA (0.2 mA of 1200 mAh), and 1 C means 1200 mA (1 times rate of 1200 mAh). High current charging will inevitably lead to a decrease in battery life. Studies have shown that the aging rate of charging with 2C is 1.63 times that of 1C charging, and as the battery ages, the aging rate is rising, so it has been in the constant current phase. Charging with the same high current will aggravate battery aging and reduce the life of lithium-ion batteries.

具体实施方式detailed description
以下结合附图以及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不限定本发明。The invention will be further described in detail below with reference to the drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
本发明的各种实施例中:通过对设备(电池供电的设备)使用的实际情况,对电池的老化率进行监测,当电池进入不同的老化阶段时,及时地对充电方式进行调整,以实现最大限度的延长电池的使用寿命,从而解决现有技术电池一直快速充电造成的电池老化加剧、寿命降低的问题。In various embodiments of the present invention, the aging rate of the battery is monitored by the actual use of the device (battery-powered device), and when the battery enters different aging stages, the charging mode is adjusted in time to achieve Maximize the service life of the battery to solve the problem of increased battery aging and reduced life caused by the rapid charging of the prior art battery.
具体地,对使用电池设备在使用过程中容量的变化进行充分监测,设备在使用过程中,根据使用电池的情况不同,电池的老化程度不同,实时地调整充电方式,以实现更大的延长电池寿命。功能模块主要包括:电池、主芯片、电源管理模块、以及适配器模块。Specifically, the capacity of the battery device is fully monitored during use, and the device is in use, depending on the condition of using the battery, the degree of aging of the battery is different, and the charging mode is adjusted in real time to achieve a larger extended battery. life. The functional modules mainly include: a battery, a main chip, a power management module, and an adapter module.
对电池充放电次数情况的监控主要根据电池管理系统(BMS,Battery Management System)中获得的数据,根据各种电池预期的使用寿命不同,设置最适当的切换点,目前所得到的数据中,智能终端的电池使用寿命要求在500次,电动自行车以及电动汽车的电池使用寿命都要求在2000次以上,容量下降到80%视为寿命结束。根据这两种常规数据和在充放电试验中获得的电池老化率的变换情况,设立合适的切换点。故此本发明实施例中,根据电池的老化程度进行充电方式调整,当BMS监测到电池的老化率达到设定的阈值时,即对充电方式进行调整。 The monitoring of the number of times of charging and discharging the battery is mainly based on the data obtained in the Battery Management System (BMS). According to the expected service life of various batteries, the most appropriate switching point is set. In the current data, the intelligence is obtained. The battery life of the terminal is required to be 500 times. The battery life of electric bicycles and electric vehicles is required to be more than 2,000 times, and the capacity is reduced to 80% as the end of life. Based on these two conventional data and the change in the aging rate of the battery obtained in the charge and discharge test, a suitable switching point is established. Therefore, in the embodiment of the present invention, the charging mode is adjusted according to the aging degree of the battery.

For example, a lithium-ion battery, the standard battery capacity of the factory is 3000mAh; the current battery capacity is 2800mA/93=93% when the battery capacity is from 2800mAh.
另外,有些情况下,是需要进行快速充电,以满足设备的使用需求,在这种情况下:在获取电池的老化率之前还包括:In addition, in some cases, it is necessary to perform fast charging to meet the needs of the equipment. In this case: before obtaining the aging rate of the battery, it also includes:

The ratio between the aging rate acquisition module 201 may be a BMS monitoring sub-module inside the power management module, or may be a BMS monitoring sub-module integrated in the battery module;

下面给出两个具体实施例,以进行详细说明:Two specific embodiments are given below for a detailed description:
实施例一:如图3所示,主要适用于便携式的终端设备,此设备的充电控制电路以及BMS监测电路都集成于主板之上;具体实现如下:Embodiment 1: As shown in FIG. 3, it is mainly applied to a portable terminal device. The charging control circuit and the BMS monitoring circuit of the device are integrated on the main board; the specific implementation is as follows:
适配器304通过电源管理模块303对电池模块301进行充电,同时,电源管理模块303内部的BMS监测子模块记录电池每次充电完成的容量监控,主芯片302显示充电的整个过程,当BMS监测子模块监测到电池容量的老化达到预设的阈值时,通过SPMI/SSBI上报给主芯片,主芯片302此时控制电源管理模块303的芯片的输入电流,以减少充电电流。减少充电电流包括两种方法:The adapter 304 charges the battery module 301 through the power management module 303. At the same time, the BMS monitoring sub-module inside the power management module 303 records the capacity monitoring of the battery after each charging, and the main chip 302 displays the entire charging process, when the BMS monitoring sub-module When the aging of the battery capacity reaches a preset threshold, the SPMC/SSBI reports the main chip, and the main chip 302 controls the input current of the chip of the power management module 303 to reduce the charging current. There are two ways to reduce the charging current:
1、不限制输入电流、只限制充电电流,此方法功耗较大。 1. It does not limit the input current and only limits the charging current. This method consumes a lot of power.
2、限制输入电流,此办法强制充电电流减小,此方法弊端在一定程度上会降低电池电量。2. Limit the input current. This method forces the charging current to decrease. The disadvantage of this method will reduce the battery power to a certain extent.
可根据产品的定义选择合适的方案,另外此方案不适用于可拆卸电池的终端设备。The appropriate solution can be selected according to the definition of the product, and this solution is not applicable to the terminal device of the detachable battery.
实施例二:如图4所示,主要适用电动自行车和电动汽车等需要可移除的充电电池,可将电池取下,电池模块上设置有充电接口;具体实现如下:适配器404对电池模块401进行充电,电池模块401内嵌电源管理子模块402和BMS监测子模块403,适配器404对电池模块401进行充电时,BMS监测子模块403采集到电池的老化程度,当电池老化率达到预设的阈值时,上报数据给电源管理子模块402,及时地限制电流的输入,此处也有同实施例一的两种限制电流的方法,但处于安全考虑,建议采用方案二,直接限制输入电流。Embodiment 2: As shown in FIG. 4, it is mainly applicable to a rechargeable battery that needs to be removed, such as an electric bicycle and an electric vehicle, and the battery can be removed, and a charging interface is disposed on the battery module; the specific implementation is as follows: the adapter 404 is opposite to the battery module 401. When charging, the battery module 401 is embedded with the power management sub-module 402 and the BMS monitoring sub-module 403. When the adapter 404 charges the battery module 401, the BMS monitoring sub-module 403 collects the aging degree of the battery, when the battery aging rate reaches a preset state. At the threshold, the data is reported to the power management sub-module 402 to limit the current input in time. There are also two methods for limiting the current in the same manner as in the first embodiment, but for safety considerations, it is recommended to adopt the second scheme to directly limit the input current.
此方案的好处在于,BMS始终和电池集成在一起,存储有电池的寿命信息,可操作性强。The advantage of this solution is that the BMS is always integrated with the battery, storing battery life information and operability.
