Vehicle motor with charging control function

Abstract

A vehicle motor with a charging control function comprises a metal casing unit, a rotor and stator unit, a charging control unit, and a heat radiation unit. The rotor and stator unit is accommodated in the metal casing unit, and linked to a power transmission module; the charging control unit includes a high heat conduction substrate arranged in the metal casing unit, a transformation module positioned in the metal casing unit and on the high heat conduction substrate and electrically connected with the rotor and stator unit and first and second batteries, and a control module arranged in themetal casing unit and electrically connected with the transformation module; and the heat radiation unit is arranged in the metal casing unit, and can simplify a transmission line. The transformationmodule and the rotor and stator unit share a heat radiation system, and thus, the production and manufacture cost can be reduced effectively, and the occupied size is reduced.

Description

technical field [0001] The invention relates to a motor for a vehicle, in particular to a motor for a vehicle with a built-in charging control function. Background technique [0002] Generally speaking, the power source of vehicles is to use internal combustion engines and burn fossil fuels as energy sources. However, due to the gradual depletion of fossil energy sources and environmental pollution problems in recent years, hybrid vehicles that use some green energy have become the new favorite in the market. On the one hand It can save energy and reduce pollution on the other hand, and the most common one at present is a hybrid electric vehicle (HEV, Hybrid Electric Vehicle). [0003] HEVs can be divided into Mild Hybrid and Full Hybrid based on the configuration of the output power. The main difference is that the light fuel electric vehicle uses the internal combustion engine as the main power source, and the output of the motor is configured. The power is low, and it is...

Problems solved by technology

[0005] However, according to this structure, no matter whether the rotor stator assembly 13 is in the electric function of converting electric energy into kinetic energy, or the power generation function of converting kinetic energy into electric energy, the electric power of the second battery 19 must be provided by the battery located in the accommodating space. The step-down circuit 18 of 12 is transmitted to the second battery 19 located in the engine compartment 11 at the front of the vehicle, which increases the complexity of the line configuration

[0006] In addition, the step-down circuit 18 steps down the high-voltage electric energy originally provided by the rotor-stator group 13 with better transmission efficiency into the second DC voltage with lower transmission efficiency, and then the second DC voltage at the rear side of the vehicle The accommodating space 12 is transmitted to the second battery 19 in the engine room 11. This long-distance low-voltage transmission will increase the loss of power transmission.
