Abstract

The invention discloses a power system of an electric car. The power system comprises a power battery, a first end, a second end, a first contactor set, a second contactor set, a double-direction DC/DC converter, a driving motor, a motor controller and a controller. The first end and the second end are connected with a power supply network, and the motor controller controls the driving motor. The controller is used for controlling the first contactor set, the second contactor set, the double-direction DC/DC converter and the motor controller. According to the power system of the electric car, the controller controls the first contactor set, the second contactor set, the double-direction DC/DC converter and the motor controller, and therefore the power battery is isolated from a high-voltage wire net, the voltage of the power battery is not limited, and optional resources are increased. The impact of the large current of the high-voltage wire net to the power battery is effectively avoided, and the power battery is better protected. The invention further discloses the electric car.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a power system of an electric vehicle and an electric vehicle with the same. Background technique [0002] With the gradual depletion of non-renewable resources such as oil and the environmental pollution caused by traditional vehicle emissions, new energy vehicles such as hybrid vehicles and pure electric vehicles are considered to be a good solution to the two major problems of the environment and resources. Among them, trolley bus, as a kind of pure electric vehicle, is one of the electric vehicles generally adopted in the city at present. However, the trolley bus in the related art is limited by the wiring of the line network, and if there is a large jump in the line network voltage, the power battery of the trolley bus is easily impacted, and there is a serious safety hazard. [0003] In the related technology, the power system of the trolleybus is based on the existing ex...
