Abstract

Disclosed is a controller driving apparatus of an electric vehicle which includes: a first switch comprising an input side with both ends linked connected to ignition switch of one or more other controllers, and an output side connected to a low-voltage DC-DC converter, a first port of a battery management system (BMS) and an electric vehicle controller; A second switch comprising an input side connected to an output terminal of a high-voltage DC-DC converter and an auxiliary battery, an output side connected to a low-voltage DC-DC converter, a first port of the BMS and the eclectric vehicle controller. Wherein the output terminal of the high-voltage DC-DC converter is connected to a second port of the BMS, and the auxiliary battery is connected to one end of the ignition switch. Finally, a third switch comprising an input side connected between the auxiliary battery and a third port of the BMS, and an output side connected to the low-voltage DC-DC converter, the first port of the BMS and the electric vehicle controller as well.

Description

technical field [0001] The present invention relates to a controller driving device of an electric vehicle, and more particularly, to a device for driving a controller of an electric vehicle when the electric vehicle is started or charged at a low speed or a high speed. Background technique [0002] As the economy develops, the demand for vehicles has grown rapidly. As the demand for vehicles has increased, exhaust gas emitted from vehicles is becoming a major factor of environmental pollution. Therefore, reduction of exhaust emissions from vehicles has been demanded, and many studies have been conducted on the development of vehicles capable of reducing exhaust emissions. [0003] In addition, rising international oil prices and the depletion of natural resources are accelerating the development of alternative energy competition. [0004] According to such a trend, automobile manufacturers in each country compete fiercely to develop next-generation automobiles. The ultim...
