Polymer lithium ion battery charging and discharging precautions

Source: Time:2017-12-25 16:04:34 frequency:

The charging current and charging voltage shall not exceed the following standards. If the specified value is exceeded, the charging and discharging performance, mechanical performance and safety of the battery may be damaged, which may cause heat and leakage.

1, charging

The charging current and charging voltage shall not exceed the following standards. If the specified value is exceeded, the charging and discharging performance, mechanical performance and safety of the battery may be damaged, which may cause heat and leakage.

1, the battery charger must be able to constant current and constant voltage charging;

2. The charging current of the single battery during charging must be below 1C;

3. The temperature range during charging is 0~+45°C;

4. The voltage during charging cannot exceed 4.23V.

2, discharge

The discharge current shall not exceed the following standards, and the discharge must be carried out within the scope of this standard.

1, the single battery discharge current must be less than 2c;

2. The temperature range during discharge is -20~+60°C;

3. The discharge termination voltage of the single battery is not less than 2.75v.

3, over discharge

It should be noted that while the cell is not in use for a long period of time, it may be in some over-discharge state with its self-discharge characteristics. To prevent overdischarge from occurring, the cell should be periodically charged to maintain its voltage above 3.0V. Overdischarge can result in loss of cell performance and battery function.
