Equalization Balancer
BAL-524D equalizer adopts the high-frequency transformer inversion and equipotential isolation coupling energy mode to realize the parallel connection of each series of batteries through the equipotential isolation coupling mode. Based on the parallel connection state, each series of batteries with different voltages can realize energy transmission and distribution, and finally realize the high-power precision balance of the battery pack. The actual equalization work is carried out by the main control chip MCU, and the inverter with ultra-low dynamic impedance obtains more than 5A equalization current. Precise transformer technology and fully symmetrical circuit design can achieve the equalization effect of ≤ 30mV.
It is suitable for high-capacity ternary lithium battery pack and lithium iron phosphate battery pack, etc. The maximum equalizing current can reach 5A, and the equalizing voltage difference can reach 30mV; Forced start switch is added to better solve the problem of poor equalization effect. |
