Balance indication: When the equalization light is on, the equalization work is turned on. The equalization light goes out, the equalization circuit sleeps. The equalization light flashes,the string indication is lost, or the circuit is faulty. Principle of equilibrium: This module is adjacent to the differential pressure equalization, and the adjacent battery voltage difference reaches 0.1V or more. The internal trigger balance is working until the adjacent battery voltage difference stops within 0.03V. There is an adjacent differential pressure when charging and discharging on the battery pack. Trigger equalization, the battery pack voltage error will be pulled back to the perfect value, reducing battery maintenance costs.
Working voltage is 2.0V-4.5V, ternary iron lithium battery is common, lithium cobalt oxide battery is not applicable. Equilibrium current:
Adjacent pressure difference is 0.1V or more (current is about 0.5-0.7A)
Adjacent pressure difference is above 0.2V (maximum equalization current is 1.2A)
The smaller the differential pressure, the smaller the equalization current.
B-, the total negative pole of the battery pack (the negative pole of the first battery)
B1, the positive electrode of the first battery
B2, the positive electrode of the second battery
B3....... and so on.
