Abstract
Abstract In an electric vehicle driven by an electric motor, a battery accumulator supplies electricity to the electric motor and a plurality of auxiliaries. A generating unit generates electricity in order to charge the battery accumulator. A detector unit detects at least one of various running conditions of the vehicle. A control unit supplies the electricity from the generating unit directly to the electric motor when the detected running condition indicates an overload condition, and gradually reduces the electricity supplied to the auxiliaries.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
130 words
An electric vehicle comprising: an electric motor for driving the vehicle; a plurality of auxiliaries mounted on the vehicle; a battery accumulator for supplying electricity to said electric motor and said auxiliaries; generating means for generating electricity in order to charge said battery accumulator; detector means for detecting at least one of running conditions of the vehicle, including a speed sensor for detecting a speed of the vehicle and an accelerator opening sensor for detecting opening of an accelerator; and control means for controlling the supply of the electricity from said generating means directly to said electric motor and for gradually reducing the electricity supplied to said auxiliaries when the detected running condition indicates the opening of said accelerator indicative of acceleration and/or overload caused by a high-grade incline climbing.
Claim 2
Dependent Claim
130 words
An electric vehicle comprising: an electric motor for driving the vehicle; a plurality of auxiliaries mounted on the vehicle; a battery accumulator for supplying electricity to said electric motor and said auxiliaries; generating means for generating electricity in order to charge said battery accumulator; detector means for detecting at least one of running conditions of the vehicle, including a speed sensor for detecting a speed of the vehicle and an accelerator opening sensor for detecting opening of an accelerator; and control means for controlling the supply of the electricity from said generating means directly to said electric motor and for gradually reducing the electricity supplied to said auxiliaries when the detected running condition indicates the opening of said accelerator indicative of acceleration and/or overload caused by a high-grade incline climbing.
