Description

Electric automobile power battery intelligent charge module
Technical field
The invention belongs to the charging electric vehicle technical field, be specially a kind of electric automobile power battery intelligent charge module.
Background technology
In recent years, along with the growing interest of people to social concerns such as energy crisis, environmental pollutions, the new-energy automobile of energy-conserving and environment-protective has become the inexorable trend of auto industry sustainable development.Wherein, first developing electric automobile has extremely important meaning to upgrading and auto industry realization great-leap-forward development transition of China's energy resource structure, will become the main technological route of national new-energy automobile strategy.
The Eleventh Five-Year Plan period, the pure electric automobile, the mixed power electric car that come into operation of Beijing reached thousand.2008 Beijing is concentrated and has been dropped into the hybrid power of 595 independent researches, pure electronic and fuel cell car during the course of the Olympic Games, and accumulative total is moved more than 370 ten thousand kilometers, transports more than 440 ten thousand person-times of passengers, realizes the electric automobile demonstration operation of maximum-norm on the Olympic history.Shanghai World's Fair in 2010 has been opened the New Times that electric motor car is used, and electric automobile becomes the most important vehicles in the Expo Site.Infrastructure such as charging station network are promptly being built in Shanghai City at present, estimate to have in two years the ranks that 20,000 above pure electric automobiles enter public transport, logistics, taxi and environmental sanitation vehicles.At the beginning of last year, department's positive tissues such as the Ministry of Science and Technology, the Ministry of Finance, the Committee of Development and Reform, Ministry of Industry and Information have advanced " thousand in ten cities " electric automobile action plan of demonstrating on a large scale, special Chinese Financial Subsidy Policies has been put into effect in research, electric automobile is promoted in Public Service Field such as public transport, taxi, public affair, environmental sanitation and the postal service demonstration that is supported in 13 cities such as Beijing, Shanghai, Chongqing, and 60,000 electric automobiles are promoted in the demonstration of plan utilization time more than 3 years.Propose in " the energy-conservation and new-energy automobile industrial development planning (2011-2020) " formulated of being taken the lead by Ministry of Industry and Information, to the year two thousand twenty, China's electric automobile recoverable amount should reach 5,000,000.
Relevant enterprises such as State Grid Corporation of China have proposed the mode of battery altering by the comparative studies to multiple charging modes.Adopt this mode, when vehicle need carry out boost charge, only the battery that needs nigh electrical changing station will need to charge was uncarted, and reinstalled the battery that is full of electricity, and vehicle can leave.The battery to be charged that electrical changing station is responsible for unloading is transported to large-scale charging station and concentrates charging.This electrical changing station changes battery, charging station concentrates the mode of charging to save user's charging interval greatly, has improved the service efficiency of vehicle.In addition, concentrate the mode of charging also can avoid the user to fill influence to battery life voluntarily soon, Ji Zhongguanli mode has also been strengthened the security reliability of battery charge greatly simultaneously.Be extensively to adapt to the demand of bus, commercial car and passenger car market different levels, need make standardized regulation parameters such as the voltage of single electrokinetic cell in groups, electric weight, sizes, with conveniently fill, the standardized management of electrical changing station.Application experience according to present electric automobile pilot conversion city, single standard power battery pack about 60-80V can cover the demand in different levels market substantially, simultaneously its volume is little, in light weight, can adapt to fill, the requirement of the standardization management of electrical changing station.Concentrated charging station must dispose a large amount of and the corresponding charging module of standard power battery pack.
At present, the bottleneck of restriction ev industry development mainly is electrokinetic cell and charging modes.Under the support and propelling of national industrial policies and science and technology item, the industry development of big capacity energy type lithium-ions battery is near international most advanced level.Current, the performance of lithium-ions battery battery cell can satisfy application requirements substantially.But, battery in groups the back take place easily in charge and discharge process that cell overcharges, problems such as overdischarge and excess temperature, have a strong impact on the useful life and the security performance of lithium-ions battery in groups.The problems referred to above have become the major obstacle of restriction lithium-ions battery industry development, also are the major technique bottlenecks of the current ev industry development of restriction.
Charger in the market, charging module are not all considered in the problem of cell equalizing charge and the charging process protection problem to cell, but these problems are left for battery producer or end user.In order to address these problems; battery producer or user are equipped with battery management system (BMS) must for each battery pack; realized by BMS: the equalizing charge of cell, cell overcharge and cross the state-detection of putting protection, cell (voltage, temperature, function such as SOC).But because the restriction in space in the electric automobile is generally not enough with the cell ability of equalization of car (with battery) BMS, can not realize efficient balance, have a strong impact on the service efficiency and the life-span of electrokinetic cell.
