ABSTRACT

In recent years, due to the increasingly serious problem of environmental pollution and the increasing consumption of oil and energy, new energy vehicles

Development, more and more governments and the world's major carmakers attention. Develop three electric vehicles

The key technology is the motor drive system consists of three parts, the vehicle control system and power management systems, steam current

Automotive battery life is short-range, low battery life, high maintenance costs and popular, therefore,

Power management technology for energy management and vehicle power battery protection control is becoming increasingly important.

This article describes the electric vehicle battery management system The main function of the system and the development of domestic and foreign presentation

Root of the problem, and introduces the principle of lead-acid batteries and key operating characteristics described

Lead-acid battery remaining amount prediction model design and features of several projects, based on a lot of battery

Charging and discharging of the experimental data, this design method is proposed to estimate the remaining battery power.

The above functional requirements, the design proposed to use the main chip microcontroller, decentralized collection

And centralized control solutions combine hardware, MCU selection,

battery parameters collection, balance and protection

Circuit, a power conversion circuit and external communications, and other major modules and hardware design based on a detailed description of

Kyle C51 microcontroller software development and design environment software solutions designed battery management system 3 The main processes: charge, discharge and static software design. Finally, the entire hardware and software system

Charging and discharging fatigue test by collecting a large amount of experimental data to verify the feasibility and stability of the hardware and software design

Keywords electric vehicles; battery management system; battery SOC estimation; SCM; charge equalization control
