Abstract
The invention relates to a battery management system of a pure electric vehicle. The battery management system comprises a battery detection module, a temperature acquisition module, an integrated management device, a 485 bus, a CAN (controller area network) bus and an instrument display; wherein the battery detection module comprises a voltage sensor and a current sensor used for detecting the voltage and current of every battery pack, the collected information of the current, voltage and temperature is transmitted by the battery detection module and the temperature acquisition module to the integrated management device through the 485 bus, the state information of every battery is displayed on the instrument display by the integrated management device through the CAN bus, the amount of residual electricity of the battery packs is calculated by the integrated management device according to the information of the current, voltage and temperature collected by the battery detection module and the temperature acquisition module, and the current and voltage of the battery packs is controlled by combining the amount of the residual electricity with running conditions of the vehicle. The battery management system of the pure electric vehicle has the beneficial effects that charging and discharging of the vehicle can be arranged reasonably, the service life of the batteries can be prolonged, the cost of vehicle maintenance can be reduced, and the control is simpler and more intelligent.
Description
Technical field
The present invention relates to a kind of battery management system, particularly a kind of battery management system of pure electric automobile.
Background technology
Modern energy crisis and oil shortage, the simultaneously pollution of auto emission has become the key factor of atmospheric contamination, and the pressure of reducing emission of carbon dioxide is increasing.Therefore greatly developing new-energy automobile is to realize that global energy safety, environmental protection and auto-industry are realized crossing over greatly, the needs of sustainable development.Along with the concern of people to problems, the research enthusiasm of electronlmobil has entered unprecedented high-tide period.Domestic production electronlmobil enterprise emerges in an endless stream.Flying power and operating cost become one of the scale of an essence of modern electronlmobil.One of key element of the flying power of decision electronlmobil: energy management part.Early stage battery management system generally only has the simple functions that detects cell pressure, temperature, electric current.The systemic-functions such as basic specification detection, estimation, communication interface, control and the data logging of battery are all failed well perfect.Insulation detects, discharges and recharges the number of times record, the battery failures analysis also is in the starting R﹠D process with functions such as online warning, battery discreteness appraisement systems.Because the imperfection of this type of technology has directly affected the flying power of electronlmobil.
Summary of the invention
