Protection Description
sleep mode. If you hold down the MANUAL ON/OFF button to activate the ESM, it
will report a protection alarm and the ALM indicator will be lit.
External short circuit
If the ESM loop is short-circuited, ESM protection will be triggered and the ESM
cannot be charged or discharged. Long-time frequent short circuiting can result in
cell or board faults, which may cause risks such as fire.
Series connection
ESMs cannot be connected in series. If they are connected in series forcibly, ESM
protection will be triggered. Operation outside the protection range will result in
board or battery damage and battery protection failure, which may cause risks such as
fire.
A.3 Gas Composition
The ESM is an enclosed battery system and will not release any gases under normal
operations.
If the ESM is used in extreme conditions, for example, in the case of fire or lightning, the
battery may be damaged and the electrolyte may leak. Because the electrolyte is mainly
organic carbonate, gases such as CO
2
, CO, and N
2
may be generated after combustion.
