Huawei ESS-240V12-9AhBPVBA04 - Battery Pack Recharge

NO TE
For example, if there is one battery pack, the battery pack capacity is 9 Ah, and the
charge current limit coecient is 0.15C, the charge current is calculated as follows:
Charge current = 1 (Number of battery packs) x 9 (Battery capacity) x 0.15 (Charge
current limit
coecient) = 1.35 A. The charge current of a battery pack is associated
with the battery capacity. A maximum of four battery packs can be connected in
parallel. Table 3-2 lists the charging time.
2. The time requirements for using the UPS to recharge battery packs are as
follows.

Note: Battery packs that have been stored for less than or equal to three
months do not need to be recharged.
3.4.2 Battery Pack Recharge
Context
NO TICE
● The following method applies only to the scenario where the UPS2000-H-10
kVA is used to recharge a battery pack.
● When connecting cables for recharging a battery pack, ensure that the cables
are correctly and securely connected.
● When recharging a battery pack, assign personnel to monitor the entire
recharge process and perform inspections periodically. If any of the following
exceptions is detected, stop charging immediately.
1. The charge voltage is greater than or equal to 288 V.
2. The surface temperature of the battery pack is greater than or equal to 45°C
(hot on your hand).
Procedure
Step 1 Correctly connect battery cables to the UPS.
