Характеристики
Principle of equilibrium:
This module is adjacent differential pressure equalization. The adjacent battery voltage difference reaches 0.1V or more. The internal trigger equalization work is performed. Until the adjacent battery voltage difference stops within 0.03V. There is adjacent pressure difference when charging and discharging on the battery pack. Trigger equalization. The battery pack voltage error is also pulled back to the desired value. Reduce battery maintenance costs.
Balanced version features:
High-precision energy transfer equalization. Exclusive equalization IC.
High current 1.2A energy transfer battery voltage balancer.
Significantly balance battery voltage. Improve overall battery pack
efficiency.
High current 1.2A energy transfer battery voltage balancer.
Significantly balance battery voltage. Improve overall battery pack
efficiency.
Parameter:
Operating voltage range: 2.0V-4.5V. ternary / iron lithium battery universal.
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.
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.
Wiring definition:
B-, the total negative pole of the battery pack (the negative pole of the first battery) B1, the positive pole of the first battery
B2, the positive pole of the second battery B3 the third battery positive pole, and so on.
