A lithium ion power battery lossless charger adopts a charging method of overall serial constant-current and monomer parallel constant-voltage to realize lossless charging on lithium ion power batteries. Lossless includes two implications: one is that charging efficiency is close to 100%, and charging power is basically lossless; and the other one is that charging and discharging are completely based on the characteristic curve of the battery, and the battery per se is completely free of damages in charging and discharging processes. The lossless charger spares a battery management system, all functions of a battery system, a charging system, a discharging system and a maintenance management system are realized only by a simple circuit, and no overcharge, overheating, over discharge, over current or short circuit occurs. The terminal voltages of all monomer batteries are completely equal when charging is finished, and no equalized charging is required. Meanwhile, there aren't any complex control chips or software which are easy to be interfered, the charger is safe, reliable, simple and practical, and the cost, volume, weight and power consumption of the charge are all one tenth of those of the traditional charger.
