Balance setting

1 Manual equalization

Manually set the voltage, operate, and when the device is in normal condition, click "Manual Balance" to modify the "Voltage Value" (the set value must be within the effective range of the current type of battery) and click OK to realize the discharge > this set value Balanced to achieve the same voltage value of all serial bits with the set value.

2 Automatic Equalization

Automatic equalization is suitable for low-speed vehicles and small-capacity battery packs. The equalization power is 5%-30%. When the device is in normal condition, click "automatic equalization" to automatically identify the highest voltage and the lowest voltage. Put it down and keep consistent with the low voltage.

3 Charge equalization

Charge equalization, operation, charge equalization generally means that the voltage of the single cells in the battery pack is carried out when the battery is half-charged, and the setting parameters of charge equalization are as follows

3-1. Balance parameters of lithium iron phosphate

Monomer overvoltage protection: 3.650V Monomer overvoltage recovery: 3.650V Forced equalization voltage: 3.650V

The equalization start voltage is set to the lowest value of the string voltage = V, the voltage difference of the equalization monomer: 0.005V, and the proportion of the equalization current: 5%~100%

3-2, ternary lithium charging equalization parameters

Monomer overvoltage protection: 4.250V Monomer overvoltage recovery: 4.200V Forced equalization voltage: 4.250V

Equalization start voltage: 4.000V Equalization monomer voltage difference: 0.005V Equalization current ratio: 5%~100%

When charging equalization, the "battery negative pole" on the front panel of the machine must be connected to the battery pack's general negative pole, the charger negative pole is connected to the machine's front panel "charging negative pole", and the charger's positive pole is connected to the battery positive pole. Before entering the balanced state, the charging current must not exceed 25A, the charging current does not exceed 5A when it reaches a balanced start (lithium iron phosphate 3.450V/ternary lithium 4.00V), and the effect of small current balance will be better.

Setting instructions

1. Start to equalize the voltage: During the charging process of connecting to the charger, the equalization work will only start when a certain string of voltages in the battery pack is equal to the set value, and the equalization will not start when the voltage is less than this set value. After equalization is started, the charging current is recommended 5A left, small current balance effect will be better.

2. Equalize the differential pressure of the cells: when charging equalization, the differential pressure of the cells of the battery pack will be equalized to the set value range, and the equalization work will be automatically stopped after reaching the set value range

3 Single overvoltage protection: During the charging equalization process, when any string in the battery pack is ≥ this set value, the system will automatically turn off the charging switch and stop charging

4. Single overvoltage recovery: During the charging equalization process, when a string in the battery pack is protected by overvoltage, the charging will stop. After the voltage of the high-voltage string drops below the set value, the system will turn on the charging switch again and resume charging.

5. Compulsory balanced voltage: In any case, after setting the balanced voltage value in the "balanced setting", return to the main interface and click the "manual balanced" button to discharge the battery pack. Within the effective voltage range, do not exceed or be less than the effective range, otherwise the battery will be over-discharged)

6. Equalization current ratio: 5%-100% for battery clip connection, 5%-50% for adapter board, (it is recommended to use according to the actual equalization situation, over-current use will cause damage to the equalization harness).
