Abstract


Electric car charging and running , an accident may occur , resulting in the power system of the rocky ledge , crush, short-circuit , cracking , leakage , thermal shock , explosion, burning, etc. , whereby a mechanical injury to the occupant , electrical injury chemical injury, battery explosion , injury and burn injury , and may lead to more bursts of accidents as well as secondary damage . Several major domestic electric vehicle research institutes has appeared the vehicle and even entire laboratory accident instantly burned to ashes . Therefore , the electric vehicle safety research and prevention technology is being caused by a high degree of attention of the world experts , and put a lot of manpower and resources for research . This paper focuses on the electric vehicle power system may be generated on the occupant injury , including electric vehicles electrical damage , the combustion explosion damage of electric car batteries , battery electrolyte leakage and battery release of harmful gases caused by injury , specific analysis their causes and possible consequences ; study of the safety of the power battery electric vehicles several common characteristics , including lead-acid batteries , nickel-metal hydride batteries , lithium -ion batteries and fuel cells , as well as their respective safety hazards may exist and produce mechanism of the safety issues . Article on car collision Laboratory of Hunan University laboratory equipment for experimental research platform to simulate real vehicle operating conditions , power battery electric vehicles experimental study of the safety analysis of the power battery change and its impact on performance in hazardous working conditions security impact of electric vehicles ; discharge characteristics by analyzing the the study power battery discharge explore effective alternative to the currently used constant current discharge method to non - constant current discharge to evaluate the performance of the actual use of the power battery electric vehicles , and preliminary establish the corresponding meet the conditions of actual use of electric vehicles with power battery discharge performance evaluation methodology . Relevant safety research and safety standards established electric vehicle safety incidents may exist on the basis of summing up the above analysis research , with reference to the existing domestic and international electric vehicle safety theory , detection methods and protection system , developed the hydrogen concentration measurement and control system for electric vehicles .
