Classification: CPC H  G  Y | IPC G  H

Claim 7:
8. A battery charging system, comprising:
a battery;
a memory that stores usage statistics of the battery; and
a controller configured to:
receive the usage statistics of the battery;
receive usage parameters of the battery that define a measurable aspect of the battery and that characterize value ranges of the measurable aspect into different usage bins, the usage bins including voltage bins and temperature bins;
calculate a wear factor based on the usage statistics and the usage parameters, including:
assigning voltage and temperature values of the received usage statistics to the voltage bins and temperature bins, respectively, defined by the received usage parameters;
determining an amount of time the battery has spent in each usage bin; and
calculate the wear factor based on the amount of time the battery has spent in each usage bin; and

control a charging rate of the battery based on the calculated wear factor.
