Battery Overvoltage
Warning
56.8V 56.8V
If the voltage is greater than the warning voltage for 10s, a
warning will be triggered and a warning message will be
sent out immediately
Battery Overvoltage
Warning Recovery
56V 56V
If the voltage is less than the warning recovery voltage for
10s, the warning will be cleared.
Battery Overvoltage
Protection

58.4V
51.2V circuit
If the voltage is greater than the protection voltage for
2s, the protection will be triggered, a pre-alarm message
will be sent out immediately, and the relay will be
opened after a delay of 3s
The 12V circuit is not affected and is allowed to continue
discharging

1. If the voltage is less than the protection recovery voltage
for 10s, the protection will be released and the relay will
be closed
2. The self-check will start after the battery voltage drops
below 57.6V with a duration of 2s and an interval of 10s. If
the discharge current is greater than 2A for 2s, the
protection will be released and the relay will be closed

If the voltage is greater than the warning voltage for 10s, a
warning will be triggered and a warning message will be
sent out immediately

1. If the voltage is less than the protection recovery voltage
for 10s, the protection will be released and the relay will
be closed.
2. The self-check will start after the cell voltage drops
below 3.6V with a duration of 2s and an interval of 10s. If
the discharge current is greater than 2A for 2s, the
protection will be released and the relay will be closed.
