Problems solved by technology

[0002] Existing electric vehicles use the electric energy in the battery as the energy source, and the battery can output a large current in the process of going uphill to complete the driving of the vehicle. In the process of braking, a lot of heat is generated on the brake device; in addition, when driving on a flat road, when encountering an emergency or a red light, it is necessary to brake, and these brakes will consume energy; the total weight of the vehicle The size directly affects the driving distance of the battery
[0003] In general, battery-powered electric vehicles generate relatively low voltage when coasting, and cannot directly charge the battery. In the existing patented technology, the voltage is boosted to charge the battery, and a power generator is required. Controller, the efficiency of recycling by this method is extremely low, the circuit is complex, the failure rate is high, the driver needs to operate frequently, and very few can really be used

Abstract

The invention discloses an energy recovery electric motor car which comprises a storage battery arranged on a car frame, a front wheel, a rear wheel, a speed regulation device, a steering gear, a DC brushless motor and a motor driver. The energy recovery electric motor car is characterized in that the motor driver not only can drive a motor to rotate, but also can charge the storage battery by using the electric energy output by the rotation of the motor; the electric motor car is equipped with a brake signal acquisition element which is electrically connected with the motor driver. The electric motor car recovers the electric energy at any time in driving, improves the service efficiency of the battery and increases the road haul of vehicles.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to an electric bicycle for energy recovery. Background technique [0002] Existing electric vehicles use the electric energy in the battery as the energy source, and the battery can output a large current in the process of going uphill to complete the driving of the vehicle. In the process of braking, a lot of heat is generated on the brake device; in addition, when driving on a flat road, when encountering an emergency or a red light, it is necessary to brake, and these brakes will consume energy; the total weight of the vehicle The size directly affects the driving distance of the battery. [0003] In general, battery-powered electric vehicles generate relatively low voltage when coasting, and cannot directly charge the battery. In the existing patented technology, the voltage is boosted to charge the battery, and a power generator is required. For the controller, the recovery efficiency o...
