详细介绍:
充电
1.1
充电电流
充电电流不得超过本标准书中规定的最大充电电流。使用高于推荐值电流充电将可能引起电芯的充放电性能、机械性能和安全性能的问题,并可能会导致发热或泄漏。
1.2 Charging voltage:
Charging shall be done by voltage less than that specified in the Product Specification (4.2V/cell). Charging beyond 4.25V, which is the absolute maximum voltage, must be strictly prohibited. The charger shall be designed to comply with this condition.
It is very dangerous that charging with higher voltage than maximum voltage may cause damage to the cell electrical, mechanical safety performance and could lead to heat generation or leakage.
充电电压
充电电压不得超过本标准书中规定的额定电压(4.2V/电芯)。4.25V为充电电压最高极限,充电器的设计应满足此条件。
电芯电压高于额定电压值时,将可能引起电芯的充放电性能、机械性能和安全性能的问题,可能会导致发热或泄漏。
1.3 Charging temperature:
The cell shall be charged within 0℃~45℃ range in the Product Specification.
充电温度
电芯必须在 0℃~45℃的环境温度范围内进行充电。
1.4 Prohibition of reverse charging:
Reverse charging is prohibited. The cell shall be connected correctly. The polarity has to be confirmed before wiring, In case of the cell is connected improperly, the cell cannot be charged. Simultaneously, the reverse charging may cause damaging to the cell which may lead to degradation of cell performance and damage the cell safety, and could cause heat generation or leakage.
禁止反向充电
正确连接电池的正负极,严禁反向充电。若电池正负极接反,将无法对电芯进行充电。同时,反向充电会降低电芯的充放电性能、安全性,并会导致发热、泄漏。
2. Discharging
放电
2.1 Discharging current
The cell shall be discharged at less than the maximum discharge current specified in the Product Specification. High discharging current may reduce the discharging capacity significantly or cause over-heat.
放电电流
放电电流不得超过本标准书规定的最大放电电流,大电流放电会导致电芯容量剧减并导致过热。
2.2 Discharging temperature
The cell shall be discharged within -40℃~60℃ range specified in the Product Specification.
电芯必须在-40℃~60℃的环境温度范围内进行放电。
2.3 Over-discharging:
It should be noted that the cell would be at over-discharged state by its self-discharge characteristics in case the cell is not used for long time. In order to prevent over-discharging, the cell shall be charged periodically to maintain between 3.6V and 3.9V.
Over-discharging may causes loss of cell performance, characteristics, or battery functions.
The charger shall be equipped with a device to prevent further discharging exceeding a cut-off voyage specified in the Product Specification. Also the charger shall be equipped with a device to control the recharging procedures as follows:
The cell battery pack shall start with a low current (0.01C) for 15-30 minutes, i.e.-charging, before rapid charging starts. The rapid charging shall be started after the (individual) cell voltage has been reached above 3.0V within 15-30 minutes that can be determined with the use of an appropriate timer for pre-charging. In case the (individual) cell voltage does not rise to 3.0V within the pre-charging time, then the charger shall have functions to stop further charging and display the cell/pack is at abnormal state.
过放电
需要注意的是,在电芯长期未使用期间,它可能会用其它自放电特性而处于某种过放电状态。为防止放电的发生,电芯应定期充电,将其电压维持在3.6V至3.9V之间。
过放电会导致电芯性能、电池功能的丧失。
充电器应有装置来防止电池放电至低于本标准书规定的截止电压。此外,充电器还应有装置以防止重复充电,步骤如下:
电池在快速充电之前,应先以一小电流(0.01C)预充电15~30分钟,以使(每个)电芯的电压达到3.0V以上,再进行快速充电。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,(个别)电芯的电压仍未升到3.0V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。
