Compatible Inverters
Please refer to the Compatible Inverter List
When BYD Battery-Box HV operates in low temperatures, the charge and discharge current is adjusted
automatically. The battery will limit the current when the operating temperature gets low. Please refer to the table
below for current parameters related to operating temperature:
Charge Current at Various Temperatures Ranges
Temperature Range (℃)
Normal Current(A)
-10~0
0.2C
0~10
0.5C
10~50
0.8C
Note: It will take 2 minutes for the charge current to adjust
Discharge Current at Various Temperatures Ranges
Temperature Range (℃)
Normal Current(A)
-10~40
Discharge current is limited to 1.4C.
If the actual discharge current is more than 1.2C, it
will be limited to 1C after 10 seconds and the current
will be recovered to 1.4C after 2 hours.
