The ESS must be disconnected from external equipment during storage, and
the ESS indicators must be off.
The storage duration starts from the latest charge time labeled on the ESS
packaging. If the ESS is qualified after charge, update the latest charge time
(recommended format: YYYY-MM-DD HH:MM) and the next charge time
(Next charge time = Latest charge time + Charge interval) on the label.
The following table lists the maximum ESS charge intervals. Charge the ESS
promptly and calibrate the SOC to at least 50%. Otherwise, the battery
performance and service life may be deteriorated.
Storage Temperature (T)
–35°C ≤ T ≤ +30°C
30°C < T ≤ 40°C
40°C < T ≤ 60°C
Note a: The interval starts from the latest charge time labeled on the ESS
packaging.
When stored in low SOC, the ESS must be charged within the maximum
interval corresponding to the SOC when the batteries are powered off. If the
ESS is not charged within the specified interval, the batteries may be
damaged due to overdischarge.
Power-Off SOC Before Storage
SOC ≥ 50%
5% ≤ SOC < 50%
SOC < 5%
Do not remove the packaging from the ESS. If charging is necessary, the ESS
must be charged by professionals as required and then returned to their
original packaging after charging.
The warehouse keeper shall collect the ESS storage information every month
and periodically report the ESS inventory information. The ESS in long-term
storage must be charged promptly.
