4.2 Daily maintenance of battery pack
1. Check the voltage data on the BMS display and the actual battery voltage value to ensure the accu-
racy of the voltage collection of the BMS. If they are inconsistent, proofreading is required. The error
between the collected voltage and the actual battery voltage does not exceed 10mV
.
2. Check the temperature collection data and actual temperature value of the BMS, and the data error
between the collected data and the actual temperature value is not allowed to exceed 3°C, to ensure
that the battery will not be charged or discharged when the temperature is too high or too low.
3. Check the BMS current collected data and actual current value, the error is not allowed to exceed
1%, to ensure that the battery will not be charged or discharged by overcurrent.
4. Check the reliability of the charging equipment to ensure that the charging equipment performs
charging according to the voltage and current regulationsent by the BMS, to ensure that the battery
will not be overcharged
.
5. Check the connection of the battery pack is good, the contact points are in normal contact, and
there is no accumulation of dust, powder, metal chips.
4.3 Caution
1. Children are not allowed to use the batteries.
2. It is forbidden to disassemble the battery.
3. Keep batteries or battery packs away from dangerous items or materials, such as corrosive chemi-
cals, dangerous machinery and equipment, and high-temperature environments
.

Code
E112
E121
E122
Solution
2. If E112 is displayed without charging or discharg-
ing, please restart the BMS once. If the problem
persists, it means that the BMS is damaged and
needs to be replaced by a professional or authorized
person.
It is recommended to charge and discharge in a high
temperature environment.
1. It is recommended to charge and discharge under
a higher temperature environment;
2. If the current ambient temperature is between
-20°C and 55°C but E122 is displayed, please restart
the BMS once. If the problem persists, please check
whether the internal plug is loose;
3. If the internal wiring harness plug is not loose, it
means that the BMS is damaged and needs to be
replaced by a professional or authorized person.
