3 Safety Evaluation
：
When Li-ion rechargeable batteries are used on above the permit voltage or current, electrolyte may disassemble,
this case will affect safety performance of Li-ion rechargeable batteries. So protection circuit module were used
in order to prevent overcharge over discharge and over current .
PCM Model：SOSHINE1865USB-3600
Safety behavior
3.1 Short circuit behavior
The battery pack is short circuited with a 200mΩ load.
The battery current must not exceed 30A and the link must be cut in less than 20ms.
3.2 Over charge protection
The battery is charged at 1C without voltage regulation. The safety IC of the battery must cut the link
when battery voltage reaches (4.275 ±0.10)V
The Safety IC must keep the link cut until battery voltage
becomes lower than (4.075 ±0.10)V. Then the charge must be possible
3.3 Over discharge protection
The battery is discharged at 1C until 2.50V / cell. The safety IC of the battery must cut the link when
battery voltage reaches (2.50±0.10)V
The MOSFET will remain closed until the battery voltage rises above the value of (2.90+/-0.10)V and a charge
current is detected.
3.4 Over current protection
The aim of this test is to check the Over current protection when there is a excess discharge current.
The safety IC (protection circuit) should trip at(7±0.5)A (depending to the IC used).
The battery resets after load if removed.
