Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, the present invention is a bidirectional DC / DC device 5 connecting a storage battery 1 and a supercapacitor 2, hereinafter referred to as a supercapacitor adapter 5 or simply an adapter 5, or an electric vehicle controller 3 embedded with a supercapacitor adapter, which can realize Control the charging of the battery to the supercapacitor, discharge the battery 1 and the supercapacitor 2 together, and boost the voltage of the supercapacitor 2 to supply power for the battery 1 side.

[0025] 1. State transition control

[0026] The working state of the adapter device can be divided into four types: charging state, connecting state, boosting state, and feedback braking state. The adapter device uses an independent MCU single-chip microcomputer as the main control chip, or shares the same MCU control chip with the electric vehicle cont...

Abstract

The invention relates to a device and a method for controlling an electric motor car provided with a super capacitor adapter. The device comprises a power circuit of the super capacitor adapter for achieving the charge of the super capacitor by a storage battery and the discharge of the super capacitor to the storage battery, a driving control circuit of the super capacitor adapter, and a controller of the super capacitor adopter for acquiring various signals of capacitor voltage and current, outputting PWM, and outputting allowable control signals by an upper bridge arm and a lower bridge arm. The device and the method can improve the starting and the acceleration performances of the electric motor car, prolong the road haul of the electric motor car, and has reliable running, low cost and wide range of application.

Description

technical field [0001] The invention relates to a battery protection device for an electric vehicle, in particular to an electric vehicle control device and method with a supercapacitor adapter. The invention can improve the starting and accelerating performance of the electric vehicle and prolong the mileage of the electric vehicle. Background technique [0002] Because of energy saving and pollution-free, electric vehicles have become the preferred means of transportation for people today. The market is constantly expanding, and the number of manufacturers is also increasing. It has almost reached the point of popularity in cities. During the use of electric vehicles, the battery is a consumable part, which is directly related to the user's use cost. The charge and discharge cycle of the battery in normal use can reach more than 300 times, but in the actual use process, it is often found that the life of the battery is far lower than this charge. The number of discharge c...
