Electromobile power platform system with integrative control

Abstract

The invention discloses an electromobile power platform system with integrative control, which comprises a power battery pack, a battery guard plate, a motor controller and a motor, The motor is connected with the motor controller through a motor three-phase power line, a motor speed signal line and a motor control signal line; the motor controller is connected with a positive electrode and a negative electrode of the power battery pack; and the battery guard plate is connected with the motor controller through a low electric quantity alarming signal line, a low voltage protecting signal line and a high voltage protecting signal line for sending low electric quantity alarming signals, low voltage protecting signals and high voltage protecting switch signals to the motor controller. According to the electromobile, the motor controller provides charging protection and discharging protection for the power battery pack, so as to overcome the problem of damage on the battery guard plate and the motor controller by surge current formed due to the fact that the battery guard plate suddenly powers off to protect the power battery pack, the efficiency and the reliability of the system are improved and the cost is reduced.

Description

technical field [0001] The invention relates to the field of traffic and automatic control, in particular to a control-integrated electric vehicle power platform system. The electric vehicle power platform system involved in the present invention is suitable for 24V to 96V electric vehicles driven by motors and high-energy secondary batteries such as lithium-ion batteries and nickel-hydrogen batteries, mainly including electric motorcycles, electric bicycles, electric scooter for the disabled, electric Recreational vehicles, golf carts, electric ATVs, light electric vehicles, AGVs and other electric vehicles. Background technique [0002] In recent years, urban traffic problems have attracted increasing attention. Although automobiles, motorcycles, and scooter are gradually popularized in the world because of their advantages of convenience, as the number of urban cars, motorcycles, and scooter for the disabled Environmental pollution and energy problems are also becoming m...

AI Technical Summary

Problems solved by technology

[0004] (1) When the MOSFET is working at a high current, it is easy to be overheated and damaged, and cannot work stably for a long time at a high current; when the main circuit of the battery pack is turned off, the MOSFET is easily damaged due to a large surge impact due to high voltage and large current Motor controller and battery protection board; In order to ensure the load balance of MOSFETs when working at high currents, the battery protection board must be equipped with MOSFETs and a load balancing control module, which is complex in technology and high in cost

[0005] (2) There is no energy feedback charging protection, which may easily cause battery overcharging

[0006] (3) Lack of low-battery alarm, which may easily cause breakdown in the middle of driving and affect driving safety
