Abstract:
1. A method for controlling regeneration of a battery for a vehicle having an electrically variable transmission comprising: determining a scaled value for a state of charge of the battery, determining a scaled value for a battery temperature, calculating an actual regeneration amount by multiplying the scaled value for the state of charge of the battery with the scaled value for the battery temperature and with a requested regeneration value; controlling the regeneration of the battery for the vehicle according to the calculated regeneration amount; wherein a state of charge range defined by the first state of charge threshold and the second state of charge threshold is greater than an ideal state of charge range for the battery; and wherein a battery temperature range defined by the first temperature threshold and the second temperature threshold is greater than an ideal temperature range for the battery.
