Issue 02 (2023-02-28)
Do not unpack batteries. Batteries should be charged during storage by
professionals as required, and they should be put back to their packaging
after charge.
The warehouse keeper should collect battery storage information every
month and periodically report the battery inventory information. The batteries
in long-term storage should be charged in a timely manner.
CA UTION
● Only trained and qualified personnel are allowed to charge batteries. Wear
insulated gloves and use dedicated insulated tools during the operation.
● Observe onsite during charge and handle any exceptions in a timely
manner.
● If a battery experiences an abnormality such as bulging or smoking during
charge, stop charging immediately and dispose of it.
AC mains input voltage requirements for charging:
– 220 V (three-phase 260–530 V AC or single-phase 176–300 V AC)
– 110 V (three-phase 130–265 V AC or single-phase 90–175 V AC)
– AC input power cables used for charging in the warehouse must have a
through-current capacity greater than 23 A.
If batteries have been stored for longer than allowed, promptly report the
event to the person in charge.
Ensure that batteries are delivered based on the "first in, first out" rule.
Handle batteries with caution to avoid damage.
Do not store batteries for extended periods.
The total storage and transportation time of the battery packs cannot exceed
eight months (starting from delivery). If it exceeds eight months, charge the
batteries and calibrate the SOC to at least 50%. Otherwise, the battery
performance and service life may be deteriorated.
If batteries have been stored for longer than allowed, promptly report the
event to the person in charge.
Dispose of deformed, damaged, or leaking batteries directly irrespective of
how long they have been stored.
The storage duration starts from the latest charge time labeled on the battery
package. If a battery 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.
Charge batteries during storage once every eight months for a maximum of
three times. Dispose of batteries if the maximum charge times are exceeded.
