Vehicle battery charge control apparatus and a vehicle battery charge control method
First Claim
1. A vehicle battery charge control apparatus comprising;
- a generator that generates power by converting regenerative energy manifesting when the vehicle decelerates to power;
a control device that controls charge/discharge of the battery;
a deceleration standby state detection device that detects a deceleration standby state of the vehicle; and
a decelerating state detection device that detects a decelerating state of the vehicle, wherein;
said control device implements control so as to start a discharge at the battery if said deceleration standby state detection device detects that the vehicle is in a deceleration standby state and implements control so as to start a battery charge by halting the battery discharge and storing the power generated at said generator if said decelerating state detection device detects that the vehicle is in a decelerating state following a discharge start.
