Capacitive active equalization board is the core component of the new generation of battery management system, specially designed for lithium battery packs and supercapacitor modules. Through capacitive energy storage and energy transfer technology, it realizes highly efficient voltage equalization between battery cells, and the capacitive energy transfer replaces resistive power dissipation, which reduces the energy consumption of the system by more than 50%, and is especially suitable for the long-term use of large-capacity battery packs, and it supports bi-directional energy flow, and equalization of charging and discharging processes can be realized. Management. Milliseconds response speed, single equalization cycle is shortened to 1/3 of the traditional solution, reducing the difference in battery aging, and increasing the cycle life by 20%-30%. Modularized structure, volume 40% smaller than inductive solutions, support 4-24 strings of battery pack flexible expansion, compatible with lithium ternary, lithium iron phosphate and other battery types. Suitable for electric vehicles, energy storage stations, drones and other high energy density scenarios, significantly improving battery pack life and safety.

  • Capacitive active equalization board is the core component of the new generation battery management system, designed for lithium battery packs and supercapacitor modules, realizing efficient voltage equalization between battery cells through capacitive energy storage and energy transfer technology.
  • 【Working voltage】 working voltage is 1.8V - 4.5V, balance voltage accuracy is within 5MV, high efficiency. 【Operating current】 balance current 0-5.5A, the smaller the balance, the smaller the current, sleep mode current is less than 0.1mA.
  • 【Applicable batteries】 quiescent current is about 12mA, 30-300AH batteries are recommended. 【Applicable scenarios】in electric vehicles, energy storage power stations, drones and other high energy density scenarios, significantly improve the life and safety of the battery pack.
  • 【Problem Solving】 Tip: When a buyer encounters a problem, make sure you take the initiative to contact us and trust in our ability to solve your problem instead of just refunding your money in return. This prevents many products from being discarded and wasted.
  • 【Product Packaging】: Equalizer *1, terminal cable *1
