Battery overdischarge and damage may occur if batteries with low SOC are stored.
Batteries should be recharged in a timely manner.
Storing batteries with low SOC may occur in the scenarios including but not
limited to the following:
● Batteries cannot be charged after commissioning and power-o.
● Batteries are not charged in time after commissioning and power-o.
● After batteries are discharged, the power grid does not supply power for a
long time and batteries cannot be charged in time.
● After batteries are discharged, they cannot enter the charging state due to a
system fault.
● Batteries are not charged immediately after EOD.

SOC Range Maximum Charging Interval
SOC ≥ 10% 30 days
8% ≤ SOC < 10% 25 days
6% ≤ SOC < 8% 20 days
4% ≤ SOC < 6% 10 days
SOC < 4% 2 hours
