Abstract :
Based on the circuit model of Lithium-ion power battery, studied the polarization voltage, charging voltage, charging current and charging temperature on the influence mechanism of charging characteristics. The online polarization voltage tracking method and constant polarization charge policy have been proposed. By the charge experiment, the charging method is verified useful and feasible. It can not only guarantee battery life, but also can greatly shorten the battery charging time.
