Solution
The battery is undervoltage, it is recommended to
charge it as soon as possible.
Check whether the charging current of the charging
device is too large.
1. Check whether the charging current of the
charging device is too large;
2. Use a current clamp to test whether the battery
input current is consistent with the displayed current.
If the difference is large, the BMS current may be
inaccurate and needs to be replaced by a professional
or authorized person.
Check whether the load of the battery is too heavy,
and appropriately reduce the load.
1. Check whether the load of the battery is too
heavy, and appropriately reduce the load;
2. Use a current clamp to test whether the battery
output current is consistent with the displayed
current. If the difference is large, the BMS current
may be inaccurate and needs to be replaced by a
professional or authorized person.
1. Check whether the battery output is short-circuit-
ed;
2. Check whether the battery output load is seriously
overloaded;
3. If E83 is still displayed after eliminating the above
conditions, restart the BMS.
Check whether the voltage of a certain cell exceeds
3.8V on the display screen, but the other voltages are
normal and basically the same. It is possible that the
battery cell is faulty and needs to be repaired.
The battery is undervoltage, it is recommended to
charge it as soon as possible.
The battery is supplied with undervoltage. Charge it
as soon as possible, otherwise the battery may be
damaged.
It is recommended to appropriately reduce the charge
and discharge current.
1. At this time, the BMS has automatically cut off the
charging and discharging current, and automatically
resumes charging and discharging when the
temperature drops, appropriately reducing the
charging and discharging current to avoid over-tem-
perature protection;
