Embodiment Construction

[0047] Certain words are used to refer to specific components in the text of this application, but those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component, and the text of this application does not refer to the differences in names. As a way to distinguish components, the difference in function of components is used as the criterion for distinction. The "comprising" mentioned in the application text is an open term, so it should be interpreted as "comprising but not limited to In ", in addition, the term "coupling" includes any direct and indirect electrical connection means. Therefore, if the text describes a first device coupled to a second device, it means that the first device can be directly electrically connected. connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

Abstract

The invention provides a power system of an electric vehicle, comprising a motor control unit, a magnetic capacitor, a switch element, a boost-up circuit and a rectifying element. For the power systemof the electric vehicle, the magnetic capacitor is utilized to replace a main battery, an auxiliary battery and a capacitor battery in a power system of a traditional electric vehicle so as to achieve aims of reducing volume, reducing weight, saving cost and improving performance.

Description

technical field [0001] The invention relates to a power system of an electric vehicle, in particular to a power system of an electric vehicle. Background technique [0002] With the rise of oil prices and the improvement of environmental protection awareness, electric vehicles have become one of the most popular means of transportation in recent years with the advantages of no gasoline, no exhaust gas, low power consumption, and low noise. As we all know, the battery is the core power source of the electric vehicle power system, and the battery in the electric vehicle power system is mainly lead-acid battery at present, the main reason is that its price is far cheaper than other types of batteries; however, the lead-acid battery is heavy , secondary pollution of acid, time-consuming charging, and very large volume. Therefore, how to improve the shortcomings of traditional lead-acid batteries has become an important issue when designing electric vehicle power systems. [000...
