When the rated energy of the battery pack is greater than 200Wh, the battery pack should be placed separately in an explosion-proof chamber and able to withstand a 1.5MPa water pressure test. The protective circuit should be placed outside the explosion-proof chamber.
B、 The maximum energy of a lithium-ion battery pack in an explosion-proof chamber should not exceed 32KWh
C、 When the rated energy of the battery pack is ≤ 200Wh, the battery management system should have single cell overcharge voltage protection, single cell overdischarge voltage protection, charging overcurrent protection, discharging overcurrent protection, output short circuit protection, and temperature protection functions
D、 When the rated energy of the battery pack is greater than 200Wh, it should meet the relevant requirements of the "Implementation Rules for the Review and Issuance of Safety Signs for Mining Products - Electrical Equipment - Explosion proof Battery Power Supply".
（2） Lithium ion batteries with a single capacity exceeding 10Ah
