4:功能描述Functional description
1）深圳市华电威科技有限公司专门针电动汽车电池、电动自行车电池、电动摩托车电池、设备电源电池、及数码相机电池等，1--32串电池包而设计保护板方案；可适用不同化学性质的锂电芯，如:(聚合物电池)Polymer,(锰酸锂电池)LiMnO2,(钴酸锂电池)LiCoO2,(三元锂电池)LiCoxNiyMnzO2,(磷酸铁锂电池)LiFePO4等。
2） 过充保护，过放保护，过流保护，短路保护。Overcharge protection, over-discharge protection, over current, short circuit protection.
6） 电芯的智能平衡，无须充电状态下，时刻侦测，时刻均衡，更好的提高均衡效率和降低均衡温度，均衡精度≤±30mV。Smart balance of batteries without charging state, the moment of detection, always balanced, better balanced to improve efficiency and reduce the temperature balance, balanced accuracy≤ ± 30mV
7）充放电过程中有相应的温度保护Provides respective temperature protection in charging and discharging
8） 4 颗LED电量显示功能，也可选择LCD电量显示功能。4 LED battery voltage display mode, LCD power consumption can also choose to display
9） 使用LCD可以显示出（Bx节数）最大电压和（Bx节数）最小电压及电量显示，更好地知道电池组的良好状态。 Using the LCD can display (Bx sessions) the maximum voltage and (Bx sessions) the minimum voltage and battery indicator (5 - Figure 4) to better know the battery in good condition
10）本产品配有测试软件，方便生产测试和出厂后的产品的跟踪,保护板预留了一个通讯接口，可用来设置监控保护电压、测试等参数。The product with test software (5 - Figure 6), after the factory to facilitate production testing and tracking of products, protection board reserved for a communication interface (5 - Figure 2) can be used to set the monitor to protect voltage testing parameter.
