The 513/524 equalizer adopts high-frequency transformer inversion and equipotential isolation coupling energy technology to realize the parallel connection of each series of batteries through equipotential isolation coupling. Based on the parallel connection state, each series of batteries with different high and low voltages realize energy transmission and distribution, and finally realize the high-efficiency and precise balance of the battery pack, The Taiwan main control chip MCU combines with the ultra-low dynamic impedance inverter to obtain the more than 5A balanced current. The precise transformer process and fully symmetrical circuit design can achieve the balanced 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.
1. Nano amorphous isolated fully symmetrical transformer ensures the minimum voltage difference:
2. American ultra-low internal resistance MOS devices constitute an ultra-low dynamic impedance inverter circuit. Achieve high power balance;
3. The control and management of intelligent MCU chip realize automatic self balancing;
4. Automatically detect the minimum voltage of the battery, stop working when the battery energy is low, and protect the battery from power loss;
5. Overcurrent fuse resistance at each series input end to ensure safety;
6. Manual forced equalization timing off function, easy to use.
7. Heat dissipation design of inverter under extreme equilibrium state of high voltage difference.
