Embodiment Construction

[0012] It needs to be further clarified that: the so-called electric vehicle in the present invention includes all relevant vehicles driven by electricity, including but not limited to electric automatic vehicles, electric buses, electric forklifts, hybrid vehicles and other related transportation or delivery vehicles.

[0013] see figure 1 , the power supply system for electric vehicles of the present invention includes a main power supply 1 and an auxiliary power supply 2, wherein the main power supply 1 is used to provide a power source for the electric vehicle, and the auxiliary power supply 2 is used for instantaneous starting, acceleration or climbing of the electric vehicle. In the case of high power, together with the main power supply 1, it provides the power source to the load of the electric vehicle, thereby making up for the lack of high-rate charge and discharge performance of the main power supply 1.

[0014] The main power supply 1 can be a battery pack formed b...

Abstract

The invention provides a power supply system for an electric vehicle. The power supply system comprises a main power supply used for providing a power source for the electric vehicle, an auxiliary power supply for helping the main power supply provide the power source for the electric vehicle, and a DC / DC (direct current / direct current) converter, wherein the auxiliary power supply is connected with the main power supply through the DC / DC converter. The power supply system has the advantages of high power density, long service life, low cost and the like.

Description

technical field [0001] The invention relates to a power supply for providing power sources to electric vehicles, in particular to a power supply system for providing power sources to electric vehicles such as electric bicycles, electric forklifts and electric buses. Background technique [0002] In recent years, with the depletion of oil resources and the seriousness of air pollution, electric vehicles have become more and more popular in the Chinese market due to their cheap, convenient and environmentally friendly features; the more common electric vehicles are usually With the rechargeable battery as the energy source, through the controller, motor and other components, the electric energy is converted into mechanical energy to move the vehicle. [0003] Due to the characteristics of the rechargeable battery itself, its power density is relatively low, which determines that the rechargeable battery as a power source has a relatively poor charge and discharge performance a...
