To keep some cells of lithium-ion batteries for vehicle from being over-charged or over-discharged, a non-dissipative bi-directional equalization charge-discharge system for lithium-ion batteries was designed with the microprocessor PIC16F877. A coaxial coil and super-capacitors was adopted as the energy relay of the equalization system, which achieved the energy transfer between the battery pack and the single cell to reduce the energy waste, and was different from the conventional method to consume the excess electrical energy. Also, this system solved the heat management problem in the balancing process.
