|
| 6 | +多节锂电池串联使用，在多次充放电后，总会出现一些电压不均衡的情况，比如有些电池电压是4.1V，有些电池的电压是4.15V。 |
|
| 7 | + |
|
| 8 | +这种不均衡的情况，会造成电压高的电池过冲，电压低的电池没有充满，从而影响整体电池组的寿命和容量。 |
|
| 9 | + |
|
| 10 | +在一些高级的应用中，比如无人机的电池，会使用专门的平衡充电器对电池进行充电。 |
|
| 11 | + |
|
| 12 | +对于一些简单应用，使用HY2213-BB3A就足够了。 |
|
| 13 | + |
|
| 14 | +HY2213-BB3A的原理很简单，它就是监测每节电池的电压，当其超过4.2V后，就开启一个放电回路，以减少此节电池的充电电流。具体放电电流可以通过电阻自定义。 |
|
| 15 | + |
|
| 16 | +HY2213-BB3A属于超低功耗器件，工作电流3.5微安，休眠电流0.5微安。 |
|
| 17 | + |
|
| 18 | +具体参数可以查看数据手册Datasheet。 |
