3.3 Battery Cabinet Storage with Low SOC

Battery modules have static power consumption and self-discharge loss after the
battery cabinet is powered off. In actual application scenarios, avoid storing
battery modules with low SOC. Promptly recharge battery modules after the
storage. Otherwise, the battery modules may be damaged due to overdischarge,
which requires replacing the battery modules.
Storage with low SOC may be triggered in the following scenarios:
1.
2.
3.
4.
Regardless of scenarios involving storage with low SOC, charge battery modules
within the maximum interval corresponding to the SOC when the cabinet is
