ABSTRACT:
Concentration of hydrogen gas generated during a process of electrically recharging a battery of an electric vehicle is maintained by discharging the hydrogen gas during the process. An electric fan is installed inside a control unit box for accommodating a motor, an electric recharger and a control apparatus. The electric fan communicates ambient air to a motor through ducts. The air is further communicated to batteries through a duct and a nozzle member. Air directed by the electric fan during operation of the electric vehicle cools the motor driver and the motor. On the other hand, air communicated by the electric fan during a process of electrically recharging the batteries cools the electric recharger and then flows from the nozzle member to the batteries, blowing off hydrogen gas generated by the batteries during the electrical recharging process.
