Patent number: 5793189Abstract: To provide an electric vehicle in which a low voltage power, obtained by conversion from a high voltage power of a main battery by a DC--DC convertor, is supplied to an operation control unit and electric equipment loads such as a lamp and is also used to charge a low voltage secondary battery, in which the main battery and the low voltage secondary battery are prevented from being over-discharged even when a main switch is left in the on-state. A low voltage power VR outputted from a DC--DC convertor is supplied to an exciting winding of a relay and is also supplied to a low voltage secondary battery through a diode. The low voltage power VR is supplied to low voltage loads through a contact of the relay. The DC--DC convertor is so constructed that the output of the low voltage power therefrom is stopped when the output voltage of the DC--DC convertor is reduced to a value less than a specified range due to the reduction in the battery capacity of the main battery.Type: GrantFiled: June 14, 1996Date of Patent: August 11, 1998Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Kenji Kawaguchi, Masayuki Toriyama, Hiroshi Tanaka, Masahide Yokoo

Patent number: 5644202Abstract: A regenerative braking control system consumes energy generated in a period corresponding to an angle .theta..sub.1 which starts in a half of a period of an AC voltage produced in a drive motor during the braking of the drive motor. The regenerative braking control system also consumes energy generated in a period corresponding to an angle .theta..sub.2 that ends at the end of a half of a period of the AC voltage. The regenerative rate of braking control system utilizes a current induced in the driving coils of the drive motor at the end of the period corresponding to the angle .theta..sub.1 to recharge a battery. By utilizing two periods to carry out the regenerative braking process, the recharging energy and the braking force can be controlled individually. Moreover, a controller monitors the electric control system to determine whether a malfunction is present. If a malfunction is detected, an electrical brake electrically brakes the drive motor.Type: GrantFiled: January 26, 1996Date of Patent: July 1, 1997Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masayuki Toriyama, Kenji Tamaki, Satoshi Honda, Shoji Motodate, Yoshihiro Nakazawa, Takaaki Fujii, Shigemi Sasaki
