System and method for vehicle power supply, power source, installation device and power adapter

Abstract

The invention relates to a system and method for vehicle power supply. The system comprises a main battery, an auxiliary power source, an external charging interface, an energy conversion unit, a control unit and a drive unit, wherein the main battery is a storage battery; the external charging interface is connected with the power source to acquire electric energy; the energy conversion unit is respectively connected with the main battery, the auxiliary power source, the drive unit and the external charging interface; and the control unit is used for controlling the main battery, the auxiliary power source, energy conversion unit and the drive unit, thereby realizing energy management and vehicle driving. The invention is characterized in that the auxiliary power source is an infrequently-used component, and is installed in the installation space of the auxiliary power source only when necessary; and when the auxiliary power source is installed, the operation mode of the energy conversion unit comprises at least one of the following: a main battery independent operation mode, an auxiliary power source independent operation mode, and a main battery/auxiliary power source common operation mode.

Description

technical field [0001] The invention relates to a vehicle power supply system and method, in particular to an electric vehicle main and auxiliary power supply system and method consisting of a main battery, an auxiliary power supply, an external charging interface, an energy conversion unit, a control unit and a drive unit. The invention also relates to a corresponding power supply, an installation device and a power supply switching device. Background technique [0002] With the increasing shortage of oil and the increasing harm of the greenhouse effect year by year, the energy saving and emission reduction potential of traditional vehicles can no longer meet the needs. Because of its high efficiency and low emissions, electric vehicles can fundamentally reduce the dependence on oil, increase the use of renewable energy, and reduce the emission of carbon dioxide and pollutants. Technology research and development, especially in the core power supply system and drive system...

Problems solved by technology

The compatibility of early computers was very poor. Each manufacturer designed computers according to their own ideas and standards. The components of each other were incompatible. When users used it, the selection range was small, the scalability was low, it was very inconvenient, and the price was expensive, which seriously restricted popularization of computer
