-BMS protection-

1.Over voltage protection

• When the BMS detects that the voltage of any cell exceeds the “over voltage protection point”, the charging circuit will be cut off.
• Once over voltage protection occurs, all cell voltages must be lower than the “over voltage protection release point” to release the over voltage protection state and reactivate the charging function.

2.Under voltage protection

• When the BMS detects that the voltage of any cell is lower than the “under voltage protection point”, the discharge circuit will be cut off.
• Once the under voltage protection occurs, it must be detected that the charger is connected before the under voltage protection can be released and the discharge function can be reactivated.

3.Charge over current protection

• When BMS detects that the charging current is greater than the “charging over current point”, the charging circuit will be shut off and the charging function will be disabled.
• Once the over current protection is triggered, the charger must be disconnected for 3 seconds before the over current protection can be removed and the charging function can be restored.

4. Overload protection

• When the BMS detects that the discharge current is greater than the “overload protection point”, the discharge circuit will be closed and discharge output will be forbidden.
• Once the overload protection is started, the overload protection can only be released and the discharge function can be resumed after the load is disconnected for 3 seconds.

5.Short circuit protection and recovery

• When the BMS hardware circuit detects positive and negative short circuit of battery output, it will immediately shut off the discharge circuit and prohibit output.
• Once the short circuit protection occurs, the short circuit protection can only be released and the discharge function can be resumed after the load is disconnected for 3 seconds.

6.Overheat protection and restoration

• When the BMS detects that the temperature of any of the groups exceeds the “over temperature protection point”, the BMS will close the charging and discharging circuits of the battery pack.
• Once over temperature protection occurs, BMS shall not allow charging and discharging functions until it detects that the temperature of all temperature senses is lower than the “over temperature release point”.

7.Temperature difference protection and recovery

• When the BMS detects that the temperature difference between the two groups exceeds the “temperature protection point”, the BMS will close the charging and discharging circuits of the battery pack.
• Once temperature difference protection occurs, BMS shall not allow charging and discharging functions until it detects that the temperature difference of all temperature senses is lower than “temperature difference release point”.

8.Low temperature protection under charging condition

• When the BMS detects that any temperature sensation is below the “low charging protection point”, the BMS closes the battery pack’s charging loop.
• Once charging low temperature protection occurs, BMS shall not allow charging function again until it detects that all temperature sensing temperatures are higher than “charging low temperature release point”.

9.Low temperature protection under discharge condition

• When the BMS detects that any temperature is below the “discharge low temperature protection point”, the BMS closes the discharge circuit of the battery pack.
• Once the discharge low temperature protection occurs, BMS shall not allow the discharge function until it detects that the temperature of all temperature senses is higher than the “discharge low temperature release point”.

–Cautions-

(1)Do not immerse the battery in water, and keep the battery in a cool dry surrounding if it stands by.
(2)Do not use or leave the battery at high temperature as fire or heater. Otherwise, it can overheat or fire or its performance will be degenerate and its service life will be decreased.
(3)Do not reverse the position and negative terminals.
(4)Do not connect the battery electrodes to an electrical outlet.
(5)Do not short circuit. Otherwise it will cause serious damage of the battery.
(6)Do not transport or store the battery together with metal objects such as hairpins, necklaces, etc.
(7)Do not use the battery in a location where static electricity and magnetic field is great, otherwise, the safety devices may be damaged, causing hidden trouble of safety.Turn off the switch on its base。
(8)Please use special lithium charger.

• It should be noted that the cell would be possible to be at a 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 about 76V(Recommended 3 months one cycle).Over-discharging may causes loss of cell performance, characteristics, or battery functions.
• Do not disassemble battery.
