Charging type motor controller with battery management function

Abstract

The invention relates to a charging type motor controller with a battery management function. The motor controller comprises a three-phase drive device, a single-chip microcomputer, a first rectifying and filtering device, a transformer, a second rectifying and filtering device, a charging interface, a multifunctional inverter, a battery management module and a battery residual capacity sampling device and is connected with a 72V power battery, a motor and a 220V external power supply. The charging type motor controller has the advantages that defects in the prior art are overcome, an electric vehicle motor controller and a charger are combined due to the fact that the electric vehicle motor controller and the charger do not work at the same time and have many identical parts such as the single-chip microcomputer and the three-phase drive device, the charging type motor controller is further integrated with a battery management system formed by the multifunctional inverter, the battery management device and the battery residual capacity sampling device, and battery pack service life is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric vehicle accessories, in particular to a rechargeable motor controller with a battery management function. 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...

Problems solved by technology

However, since the four major systems are produced by different manufacturers, the cooperation between the systems produced by different manufacturers will result in poor matching, communication methods need to be shared, resource waste, and some functions are insufficient or redundant.
