New energy charging system convenient to use

Abstract

The invention relates to a new energy charging system convenient to use, which comprises a charging pile, and a charging socket, a vehicle-mounted charger, a high-voltage control box and a vehicle control unit VCU which are electrically connected, the charging pile is connected with a charging gun, a mechanical arm is arranged on the charging pile, and the mechanical arm comprises a base and at least five sections of knuckle arms which are arranged in sequence; the base rotates or deflects relative to the adjacent knuckle arms, the adjacent knuckle arms rotate or deflect relative to each other, the tail end knuckle arm is provided with a supporting frame which rotates relative to the fifth knuckle arm and is used for fixing a charging gun, the high-voltage control box is electrically connected with a power battery and a DC / DC converter, the DC / DC converter is connected with a storage battery, and a binocular camera is adopted for conducting charging socket recognition and positioning distance measurement. The mechanical arm of the charging pile drives the charging gun and the charging socket to be plugged in and pulled out in a matched mode through relative rotation or deflection, the charging gun is folded and stored, new energy charging is carried out under the control of the vehicle control unit VCU, and the use convenience, flexibility, reliability and safety of new energy charging are improved.

Description

technical field [0001] The invention relates to an easy-to-use new energy charging system, which belongs to the technical field of charging systems. Background technique [0002] A new energy vehicle is a vehicle that includes a power battery as an energy storage power source and drives an electric motor to drive. Rechargeable batteries mainly include lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries and lithium-ion batteries. With the continuous improvement of the charging speed and the continuous improvement of the performance of the charging system, it can meet the needs of fast charging in many different application situations. The new energy charging system in the prior art generally includes charging piles, charging sockets, on-board chargers, high-voltage control box PDUs, power batteries, charging indicator lights, high-voltage wires, etc. When using, pull out the charging gun on the charging pile and insert it Corresponding to the car ch...

Problems solved by technology

[0003] Because users are not familiar with manual operation, when the charging gun is coupled with the socket, the virtual connection is prone to poor contact or error, or the charging timing is prolonged. Public service and self-charging system charging, reinserting the charging gun and cable management have potential safety hazards. The construction of charging stations and the development of autonomous driving technology have increased the demand for unmanned or automatically operated charging systems. In the prior art, mechanical mechanisms that only operate in two-dimensional or three-dimensional environments are difficult to meet the needs of different new energy vehicle signals. Rear right, left front, positive direction and other orientations and inclinations of the charging port are plugged in, which limits the flexibility and safety of the new energy charging system.
