Abstract

The invention relates to a multi-functional charging type motor controller. The motor controller comprises a three-phase driving device, a singlechip microcomputer, a first rectification filter device, a transformer, a second rectification filter device, a charging interface, a DC-DC module, a multi-functional inverter, a battery management device and a battery stored electric quantity sampling device, wherein the motor controller is connected with a 72V power battery, a motor, a 220V external power supply and a 12V vehicle-mounted battery, a power receiving end and six power output ends are arranged on the multi-functional inverter, the 72V power battery comprises six 12V battery blocks, and the six power output ends on the multi-functional inverter are in one-to-one corresponding to the six 12V battery blocks. By the motor controller, the defect of the prior art is overcome, and the four-in-one device integrates the motor controller, a battery management system, a charger and the DC-DC module; and by the four-in-one device, the matching problem of an independent system can be solved, resources are integrated, joint resources are utilized, and the most maximum functions are achieved by the simplest hardware base.

Description

technical field [0001] The invention relates to the technical field of electric vehicle accessories, in particular to a multifunctional rechargeable motor controller. Background technique [0002] The four main systems of electric vehicle electrical system are motor controller, battery management system (BMS), charger and DC-DC. [0003] The motor controller controls the motor to work according to the set direction, speed, angle and response time through the active work of the integrated circuit. The application range of the motor is wider, the output efficiency is higher, the noise is lower, and the like. [0004] The battery management system is commonly known as the battery nanny or battery steward, mainly for the intelligent management and maintenance of each battery unit, to prevent the battery from overcharging and overdischarging, to prolong the service life of the battery, and to monitor the status of the battery. [0005] The charger adopts high-frequency power su...
