Claim of US Patent No. 9,225,186

1. A method for controlling charge of a battery, comprising:
when charging a battery, monitoring a temperature of the battery in real time, and acquiring a corresponding dynamic factor
according to the temperature of the battery, wherein the dynamic factor is used for characterizing a dynamically regulating
component of a charge current coefficient during the charge process;

calculating a maximum allowed charge current according to the dynamic factor and preset static factors, wherein the static
factors are used for characterizing fixed components of the charge current coefficient during the charge process;

controlling the charge of the battery according to the maximum allowed charge current;
wherein the calculating a maximum allowed charge current according to the dynamic factor and preset static factors comprises:
calculating a sum of the dynamic factor and the preset static factors, and acquiring the charge current coefficient according
to the calculated result;

calculating a product of the charge current coefficient and a battery nominal capacity, and using the calculated result as
the maximum allowed charge current.
