18.1.2.3
过放电
Over-Discharging
电池长期未使用，它可能会因其自放电特性而处于过放电状态。为防止过放电的发生，
为避免电池过放，应定期（约半年）给电池补电，保持 30~50%电量。过放电会导致电池性能
下降、电池功能的丧失。
It should be noted that the battery would be at over-discharged state by its self-discharge
characteristics in the case the battery is not used for a long time .in order to prevent
over-discharging, the battery shall be charged periodically（about half a year）to maintain
Soc30~50%.Over-discharging may cause battery performance degradation and loss of battery
function.
充电器应有装置来防止电池放电至低于本规格书规定的截止电压。此外，充电器还应有
装置以防止重复充电，步骤如下：电池在标准充电之前，应先以一小电流（
0.1C
）预充电
15~30
分钟，以使电池的电压达到 12V 以上，再进行标准充电。可用一记时器来实现该预充电步骤。
如果在预充电规定时间内，电池的电压仍未升到
12V
以上，充电器应能够停止下一步快速充
电，并显示该电芯/电池正处于非正常状态。
Charger should be installed to prevent the battery discharge below the cut-off voltage to this
specification. In addition, the charger should also device to prevent repeated charging. The steps are
as follows: the battery in the standard charge before, should first with a small current (0.1C) pre
charging for 15~30 minutes, so that the battery voltage reaches above 12V for standard charging, a
timer to achieve the pre-charge process. If in the pre charge time, battery voltage does not rise more
than 12V, the charger should be able to stop the next step fast charging, and display the electric core
/ battery is in a non-normal state.
18.2 警告、注意及提醒 Warning, Notice and Caution
警告
1. 对电池进行充放电测试时，请使用锂离子电池专用测试设备，严禁使用普通恒流恒压
源等不能限压限流设备对电池进行充放电，以避免电池被过充过放而引起电池功能失效或发
生危险；
Please use special testing equipment for Li-ion battery when doing charging and discharging
tests. Common CC/CV power supply etc. are forbidden, in order to avoid disabling battery
functions or potential dangerous caused by over-charge and over discharge.
2.
充电器需要有监测电池充满电的装置。充电器使用通过定时，电流检测或开路电压检
测电池的满电状态，当充电器检测到电池充满电时，应停止充电。电池不能用持续充电（涓
流充电）方法充电。
The charger shall be equipped a full charge detection. The charger shall detect the full-charged
state by a timer, current detection or open circuit voltage detection. When the charger detects the
