Abstract:
A method and apparatus for fast charging a battery with optimal charging. In an arrangement, a system includes a battery charger for applying a voltage to a rechargeable battery; and a controller coupled to the battery charger and monitoring at least one of a battery voltage, a battery temperature, and the current flowing into the battery; wherein the system is configured to apply a charging current from the battery charger by calculating an open cell anode voltage and an anode resistance of the battery, and determining the charging current. In additional arrangements, lithium ion plating is prevented by the charging current. Additional methods and arrangements are disclosed.

Claim (Index 18):
The method of  claim 11  wherein the anode resistance is determined by one of:\n fitting cycling data obtained at nominal and elevated charge rates for a battery to a degradation model that includes lithium plating degradation effects dependent on the anode resistance; and \n performing a pulse scan test on a battery, wherein a combination of charge pulse, relaxation, discharge pulse and relaxation is applied to the battery at different rates until a rate is determined where effective impedance derived from a response to a charge pulse differs from the impedance derived from discharge pulse; subsequently, after finding a limiting charge rate, the anode resistance is found by using known total cell impedance and the open cell voltage anode for the depth of discharge and the battery temperature of the test.
