Problems solved by technology

[0002] At present, electric vehicles on the market generally use a battery or a battery pack as a power source. According to the structure of each vehicle, different batteries need to be configured to provide different currents. Since the existing mature battery manufacturing technology is to produce 20AH batteries, this configuration method is limited. If a single high-current battery (such as a 40AH battery) is used to supply power to the electric vehicle through the controller for the continuous mileage of the electric vehicle, it will be difficult to manufacture and costly to realize.

Embodiment

[0011] Embodiment: a dual power system for electric vehicles, including a motor 1 to output power to the electric vehicle, the motor 1 is a dual-circuit motor, the winding of the dual-circuit motor is composed of two electrical windings connected in parallel, and the two electrical The windings are powered one by one by two identical power sources.

[0012] The two electrical windings are powered by two identical power sources one by one: the two power sources are respectively composed of batteries 2 and controllers 3 of the same specification, and each battery 2 is connected to each of the corresponding controllers through each controller 3. The electrical winding forms a power supply loop.

[0013] The motor 1 is a three-phase motor.

[0014] The connection structure between each electric winding of the motor 1 and each controller 3 is a star connection structure.

[0015] The power source that can be manufactured through the same two sets of existing mature technologies c...

Abstract

The invention discloses a dual power system for an electric vehicle, which comprises a motor outputting power to the electric vehicle, the motor is a dual-circuit motor, the winding of the dual-circuit motor is composed of two electric windings connected in parallel, and the two electric windings Powered by two identical power sources in one-to-one correspondence. The power source that can be manufactured through the same two sets of existing mature technologies corresponds to the two sets of electrical windings connected to the dual-circuit motor to form power supply back to the dual-circuit motor. The currents of the two circuits of electric power are superimposed to form double the electric current, which is provided to the motor of the electric vehicle as the total power source, which avoids the manufacturing difficulty faced by a single high-current battery.

Description

technical field [0001] The invention relates to a power system for an electric vehicle, in particular to a power system that provides dual power to a motor of the electric vehicle. Background technique [0002] At present, electric vehicles on the market generally use a battery or a battery pack as a power source. According to the structure of each vehicle, different batteries need to be configured to provide different currents. Since the existing mature battery manufacturing technology is to produce 20AH batteries, this configuration method is limited. If a single high-current battery (such as a 40AH battery) is used to supply power to the electric vehicle through the controller for the continued mileage of the electric vehicle, it will be difficult to manufacture and expensive to manufacture. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a dual power system for electric vehicles, which can provide elec...
