下面对本实施例的充电过程进行说明。The charging process of this embodiment will be described below.
将充电器100的电源输入接口101与外部供电电源连接，将电源输出接口102和电池200连接。The power input interface 101 of the charger 100 is connected to an external power supply, and the power output interface 102 is connected to the battery 200.
可选地，电芯的信息可为电芯的电压，其对应的充电过程如下：Optionally, the information of the battery cell may be the voltage of the battery cell, and the corresponding charging process is as follows:
充电器100和电池200连接后，先不开启对电池200的充电过程，也就是控制充电开关104处于断开的状态，充电器100的控制电路103先获取电池200的电压信息，即获取电池200的多个电芯的电压。After the charger 100 and the battery 200 are connected, the charging process of the battery 200 is not started, that is, the charging switch 104 is controlled to be in an off state. The control circuit 103 of the charger 100 first obtains the voltage information of the battery 200, that is, obtains the battery 200. The voltage of multiple cells.
控制电路103根据电池200的多个电芯的电压，控制是否导通充电开关104。The control circuit 103 controls whether or not the charging switch 104 is turned on according to the voltages of the plurality of cells of the battery 200.
若多个电芯中存在电压小于预设电压值的电芯，或者，对于多个电芯中包括并联的电芯的电池200，存在并联的两个电芯之间的电压差大于预设电压差值时，控制电路103控制充电开关104继续处于断开的状态；对于多个电芯中包括并联的电芯的电池200，若多个电芯中不存在电压小于预设电压值的电芯且不存在并联的两个电芯之间的电压差大于预设电压差值时，控制 电路103控制充电开关104导通；对于多个电芯中不包括并联的电芯的电池200，若多个电芯中不存在电压小于预设电压值的电芯，则控制电路103控制充电开关104导通。If there are cells with a voltage lower than a preset voltage value in the plurality of cells, or, for a battery 200 including a plurality of cells with parallel cells, the voltage difference between the two cells in parallel is greater than the preset voltage When there is a difference, the control circuit 103 controls the charging switch 104 to continue to be in an off state. For a battery 200 including a plurality of cells including parallel cells, if there is no cell with a voltage lower than a preset voltage value in the plurality of cells When there is no voltage difference between two parallel cells, the control circuit 103 controls the charging switch 104 to be turned on. For a battery 200 that does not include parallel cells among multiple cells, If there is no battery cell with a voltage lower than the preset voltage value in each of the battery cells, the control circuit 103 controls the charging switch 104 to be turned on.
可以理解的是，在控制电路103控制充电开关104导通后，充电器100就开启了为电池200充电的过程。随着充电过程的进行，多个电芯的电压会发生变化，可每间隔预设时长获取一次电池200的多个电芯的电压，在一次获取过程中，若多个电芯中存在电压小于预设电压值的电芯，或者，对于多个电芯中包括并联的电芯的电池200，存在并联的两个电芯之间的电压差大于预设电压差值时，控制电路103控制充电开关104断开，以切断充电器100对电池200的继续充电；对于多个电芯中包括并联的电芯的电池200，若多个电芯中不存在电压小于预设电压值的电芯且不存在并联的两个电芯之间的电压差大于预设电压差值时，控制电路103不执行操作，即充电开关104继续处于导通的状态，充电器100继续为电池200进行充电；对于多个电芯中不包括并联的电芯的电池200，若多个电芯中不存在电压小于预设电压值的电芯，控制电路103不执行操作，即充电开关104继续处于导通的状态，充电器100继续为电池200进行充电。It can be understood that, after the control circuit 103 controls the charging switch 104 to be turned on, the charger 100 starts the process of charging the battery 200. With the progress of the charging process, the voltages of multiple cells will change. The voltage of multiple cells of the battery 200 can be obtained once every preset time interval. During the acquisition process, if the voltage in multiple cells is less than For a battery cell with a preset voltage value, or for a battery 200 including a plurality of battery cells in parallel, when the voltage difference between two parallel cells is greater than a preset voltage difference, the control circuit 103 controls charging The switch 104 is turned off to cut off the continuous charging of the battery 200 by the charger 100. For the battery 200 including a plurality of cells including parallel cells, if there is no cell with a voltage lower than a preset voltage value in the plurality of cells and When there is no voltage difference between the two battery cells connected in parallel greater than the preset voltage difference, the control circuit 103 does not perform an operation, that is, the charging switch 104 continues to be on, and the charger 100 continues to charge the battery 200; The battery 200 does not include a parallel battery among the multiple batteries. If there is no battery with a voltage lower than a preset voltage value in the multiple batteries, the control circuit 103 does not perform an operation, that is, the charging switch 104 continues to be in an on state. Charger 100 continues to charge the battery 200.
其中，预设电压值可为1.5v～2.5v之间的任一值，可选地，预设电压值为2v。The preset voltage value may be any value between 1.5v and 2.5v, and optionally, the preset voltage value is 2v.
预设电压差值可为1.5v～2.5v之间的任一值，可选地，预设电压差值为2v。The preset voltage difference may be any value between 1.5v and 2.5v, and optionally, the preset voltage difference is 2v.
当多个电芯中存在电压小于预设电压值的电芯时，说明小于预设电压值的电芯已经不能继续使用，若继续为其充电，可能造成事故。对于多个电芯中包括并联的电芯的电池200，若存在并联的两个电芯之间的电压差大于预设电压差值，电压较大的电芯先被充满，电压较小的电芯后被充满，两个电压的压差越大，被充满所用的时长的差距就越大，那么先被充满的电芯在充满后被继续充电的时长就越长，发生火灾等事故的可能性就越大。When there are batteries with a voltage lower than a preset voltage value in multiple batteries, it means that the batteries with a voltage lower than the preset voltage value can no longer be used. If they continue to be charged, it may cause an accident. For a battery 200 including a plurality of cells in parallel, if the voltage difference between the two cells in parallel is greater than a preset voltage difference, the cell with the higher voltage is filled first, and the cell with the lower voltage is charged first. After the core is fully charged, the larger the voltage difference between the two voltages, the greater the difference in the length of time it takes to be fully charged. Then the longer the battery that is fully charged after being fully charged, the longer it will continue to be charged. The greater the sex.
因此，本实施例中的充电器通过设置具有上述功能的控制电路以及充电开关，增加了充电的安全性。Therefore, the charger in this embodiment increases the safety of charging by providing a control circuit and a charging switch having the functions described above.
可选地，电芯的信息还可为电芯的温度，其对应的充电过程如下：Optionally, the information of the battery cell may also be the temperature of the battery cell, and the corresponding charging process is as follows:
充电器100和电池200连接后，立即开启对电池200的充电过程，也就 是控制充电开关处于导通的状态，充电器100的控制电路103每间隔预设时长获取一次电池200的温度信息，即获取电池200的多个电芯的温度。After the charger 100 and the battery 200 are connected, the charging process of the battery 200 is immediately started, that is, the charging switch is controlled to be in an on state. The control circuit 103 of the charger 100 obtains the temperature information of the battery 200 every preset interval, that is, Obtain the temperatures of multiple cells of the battery 200.
在一次获取过程中，控制电路103根据电池200的多个电芯的温度，控制充电开关104是否继续处于导通的状态，也就是充电器是否继续为电池200充电。During an acquisition process, the control circuit 103 controls whether the charging switch 104 continues to be in an on state according to the temperatures of multiple cells of the battery 200, that is, whether the charger continues to charge the battery 200.
若多个电芯中存在温度大于预设温度的电芯，则控制电路103控制充电开关104处于断开的状态；以切断充电器100对电池200的继续充电；If there are cells with a temperature higher than a preset temperature in the plurality of cells, the control circuit 103 controls the charging switch 104 to be in an off state; to stop the charger 100 from continuing to charge the battery 200;
若多个电芯中不存在温度大于预设温度的电芯，则控制电路103不执行操作，即充电开关104继续处于导通的状态，充电器100继续为电池200进行充电。If there are no cells with a temperature higher than the preset temperature in the plurality of cells, the control circuit 103 does not perform an operation, that is, the charging switch 104 continues to be in an on state, and the charger 100 continues to charge the battery 200.
其中，预设温度可为大于等于40℃的任一值，可选地，预设温度可为45℃。The preset temperature may be any value greater than or equal to 40 ° C, and optionally, the preset temperature may be 45 ° C.
当多个电芯中存在温度大于预设温度的电芯时，说明该电芯已经被过充，容易发生起火事故，若继续为其充电，可能发生火灾。When there are batteries with a temperature higher than the preset temperature in multiple batteries, it means that the batteries have been overcharged, which is prone to fire accidents. If they continue to be charged, a fire may occur.
因此，本实施例中的充电器通过设置具有上述功能的控制电路以及充电开关，增加了充电的安全性。Therefore, the charger in this embodiment increases the safety of charging by providing a control circuit and a charging switch having the functions described above.
可选地，电芯的信息还可为电芯的电流，其对应的充电过程如下：Optionally, the battery cell information may also be the battery cell current, and the corresponding charging process is as follows:
充电器100和电池200连接后，立即开启对电池200的充电过程，也就是控制充电开关处于导通的状态，充电器100的控制电路103间隔预设时长获取电池200的电流信息，即获取电池200的多个电芯的电流。After the charger 100 and the battery 200 are connected, the charging process of the battery 200 is immediately started, that is, the charging switch is controlled to be in an on state. The control circuit 103 of the charger 100 obtains the current information of the battery 200 at a preset interval, that is, obtains the battery Current of more than 200 cells.
在一次获取过程中，控制电路103根据电池200的多个电芯的电流，控制充电开关104是否继续处于导通的状态，也就是充电器是否继续为电池200充电。During one acquisition process, the control circuit 103 controls whether the charging switch 104 continues to be in an on state according to the currents of multiple cells of the battery 200, that is, whether the charger continues to charge the battery 200.
若多个电芯中存在电流大于第一预设电流或者电流小于第二预设电流的电芯，则控制电路103控制充电开关104处于断开的状态，以切断充电器100对电池200的继续充电；If there are batteries with a current greater than the first preset current or a current less than the second preset current in the plurality of cells, the control circuit 103 controls the charging switch 104 to be in an off state to cut off the continuation of the battery 200 by the charger 100 Charge
若多个电芯中不存在电流大于第一预设电流或者电流小于第二预设电流的电芯，则控制电路103不执行操作，即充电开关104继续处于导通的状态，充电器100继续为电池200进行充电。If there are no cells with a current greater than the first preset current or a current less than the second preset current among the plurality of cells, the control circuit 103 does not perform an operation, that is, the charging switch 104 continues to be in an on state, and the charger 100 continues The battery 200 is charged.
其中，第一预设电流可为电池200的电芯能够承受的最大电流，第二预 设电流可为接近0的电流值。The first preset current may be the maximum current that the battery cell can withstand, and the second preset current may be a current value close to zero.
当多个电芯中存在电流小于第二预设电流的电芯时，说明多个电芯中存在不能继续使用的电芯，不能继续使用的电芯的电阻较大，导致与其串联的电芯以及自身的电流较小，并会导致与其并连的电芯的电流较大。若不能继续使用的电芯继续被充电，则容易发生起火事故。When there are cells with a current smaller than the second preset current in the plurality of cells, it means that there are cells that cannot be used any more, and the resistance of the cells that cannot be used further is large, resulting in a cell connected in series with the cell. And its own current is small, and will lead to a larger current of the battery cells connected in parallel with it. If the batteries that cannot be used continue to be charged, a fire accident is likely to occur.
当多个电芯中存在电流大于第一预设电流的电芯时，一是可能充电器与电池200不适配，二是可能多个电芯中存在不能继续使用的电芯，该不能继续使用的电芯的电阻较大，导致与其串联的电芯以及自身的电流较小，与其并连的电芯的电流较大。上述两种情况均有可能引起起火事故。When there are cells with a current greater than the first preset current in the plurality of cells, one is that the charger may not be compatible with the battery 200, and the other is that there may be cells in the plurality of cells that cannot continue to be used, which cannot be continued. The resistance of the used battery cell is large, resulting in a small current in the battery cell connected in series and itself, and a large current in the battery cell connected in parallel with it. Both of the above situations may cause fire accidents.
因此，本实施例中的充电器通过设置具有上述功能的控制电路以及充电开关，增加了充电的安全性。Therefore, the charger in this embodiment increases the safety of charging by providing a control circuit and a charging switch having the functions described above.
