Problems solved by technology

When an electric vehicle goes uphill or overtakes another car, it needs to provide a large current and high voltage to the motor. Ordinary batteries generally cannot meet this condition, which makes the power of the electric vehicle insufficient, and it is easy to overload the battery and shorten the life of the battery.
In addition, the renewable energy conversion and recovery device must be fixedly installed on the chassis of the electric vehicle, so the balance of the chassis of the electric vehicle must be considered

Embodiment Construction

[0012] The electric vehicle energy recovery control circuit diagram is shown in Figure 1. Control circuit Q1 composed of microcomputer and DMOC645 electric speed controller (American Sun Electric Company), permanent magnet reluctance motor A, contactors J2 and J1 connected in series in the motor circuit, contactors connected in series in the generator circuit J3, diodes D1, D2 are the same as the corresponding parts in the existing electric vehicle energy recovery control circuit. The control circuit Q1 is mainly responsible for program control of functions such as speed regulation, braking, and energy recovery. A permanent magnet reluctance motor can be used as both a motor and a generator. The difference is the use of high and low voltage charging branches. Among them, the high-voltage charging branch is composed of a battery pack F1, a DC diode D3 and a large-capacity supercapacitor C1, and the battery pack F1 is connected in reverse series with the diode D3 and then conn...

Abstract

The present invention is energy recovering control circuit for electromobile and electromobile chassis with the circuit, belongs to the field of electromobile technology, and aims at solving the problem of recovering all the converted electric energy. The energy recovering control circuit consists of mainly a control circuit comprising microcomputer and electric speed regulating controller, a trigger in the motor loop, a contactor in the generator loop, a diode, two accumulators to constitute one high voltage charging branch and one low voltage charging branch connected in parallel, and a DC reversing step up circuit between two charging branchs. The present invention is used in chassis of electromobile, including electromobile with renewable energy source.

Description

technical field [0001] The invention relates to an electric vehicle energy recovery control circuit and a chassis of an electric vehicle, in particular to an electric vehicle energy recovery control circuit capable of converting various renewable energy sources into electric energy and recovering the electric vehicle during operation and a special electric vehicle chassis for renewable energy. It belongs to the technical field of electric vehicles. technical background [0002] There are many renewable energy sources in the operation of electric vehicles, such as downhill, sliding, braking, deceleration, high-speed vibration, high-speed wind speed, and solar energy, etc., which can be converted into electric energy. At present, there are many devices for converting and recovering the above-mentioned renewable energy in the field of electric vehicles, but they have a common shortcoming that they can only recover a part of the electric energy with a stable current and voltage ...
