Will look at present, electric car most the technology of core is batteries, electric machinery, electronic-controlled technology. Because the application of these 3 technologies is each report motor-car,need and the add boat course of development that affects vehicle directly, key that quickens the parameter such as time technology. Among them electronic-controlled in most the function of core is batteries management system (Battery Management System) abbreviation BMS.
The eleventh that held in Beijing on March 28 the peak meets green car policymaker on, association of industry of Chinese power source is standing the batteries safety problem with respect to green car did vice-president Fang Yingmin important speech.
He expresses: "Lithium ion batteries has been afraid of the character that charges to had been afraid of discharge again already as a result of its, industry is using batteries management system at present (BMS) , pass those who command battery to charge too namely the safe target that has reached discharge process to ensure batteries is dead, what BMS basically solves is batteries safety problem. At the same time people increased n of batteries the rest for its again (SOC) with batteries health index (SOH) reach batteries group to detect absolutely wait for add function. " this is going up somehow again the security that guaranteed batteries.
GPLP rhinoceros finance and economics consults relevant data discovery, to batteries condition estimation it is estimation SOC, SOP and SOH normally. SOC (state of report of carry on one's shoulder) say simply even if batteries still goes how many report; SOC is the most important parameter in BMS, because other everything is a foundation with SOC, so its precision is mixed rash club sex (also call error correction ability) all in all. If do not have accurate SOC, add again much protection function to also cannot make BMS works normally, because batteries often can is in,be protected condition, cannot prolong the life of batteries more.
