Abstract
Countries around the world attach great importance to energy and environmental issues e increasingly prominent, the hybrid electric vehicle (HEV) for its low emissions, noise and low, as one of the key development of electric vehicles, battery energy management system (BMS), is mercialization of electric vehicles, the key to the practical, and hybrid electric vehicle driving conditions plex, a great influence on the life of the battery, lithium battery life is limited. Therefore, the research and design of hybrid electric vehicle battery management system is necessary.
Hybrid electric vehicle battery management system is to ensure that an important means of the power cell, which is responsible for monitoring battery parameters, including voltage, current, temperature, power, etc.. Also provides the necessary parameters to the energy of the assembly control.
This article describes a battery management system, research status, as well as hybrid technology requirements of the battery, the battery management system gave a brief overview and introduction to the basics of the battery management system, and its analysis, based on the battery management system design requirements. Followed by lithium-ion battery, for example, the estimate of the operating characteristics of the lithium-ion battery and battery remaining capacity (SOC). Finally, the hybrid electric vehicle battery management system hardware and software design.
