Today's Chinese electric car has three major changes: the development of Chinese automobile is tight with the time development to the quality of the high-end; The world the development of the automobile is undertaking the mission, as it should be make the car more suitable for human sustainable development; The expectations of the whole society for car is more and more big, the embedded for life is more and more deep, society is moving towards a new era of the development of the carIn 2018 China's BBS held in Beijing, vice chairman of the CPPCC national committee wan made a speech.

Mobile phones charging while playing, which is it in the power supply? Small make up specialized consultation with three friends in mobile R&D, they gave to the conclusion that in The battery Power increases, on the basis of a mobile phone is the charger power supply Play while charging mobile phone, mobile phone consumption of electricity is first electric charger, if the charger current shortage situation, at the same time will consume the battery.

Recently, at the invitation of the host Fang Jie can science and technology, Shanghai star "new energy automobile big classroom" ushered in the constant research and development director, Mr Cheng Kai for OEMS, PACK enterprises, batteries, solution providers such as industry elite to do "super manganese acid lithium technology and application of" the theme of the speech, see below:Japan and South Korea enterprise will manganese acid lithium battery widely used in international new energy vehicles main brandsAESC, Toshiba, Hitachi, Japan and South Korea, such as LG battery LEJ will manganese acid lithium batteries are widely used in Japan, Korea, Europe and the United States and other mainstream brand new energy vehicles.

The industry is at the time of new energy vehicles BYD, new energy vehicles leading enterprise, got into the whirlpool of profits collapsed because subsidies, decline in profitability.

Liu Weilong, Wang Lifang, Wang Liye, Power Electronics and Power Transmission Key Laboratory of Chinese Academy of Sciences, researchers at the University of Chinese Academy of Sciences, pointed out in 2018 the first phase of the proceedings of electro technics that energy state (SOE) is the electric car power battery important status indicators, which directly affects the range of electric cars, affected by the working condition of the electric car significantlyTo estimate, based on the working condition of electric cars, SOE to SOE estimation method, mode recognition algorithm, launches the research condition of prediction algorithm, based on the model battery residual energy state (SOR) estimation method, based on the recognition algorithm of running condition of information entropy theory, the application of the theory of Markov chain prediction algorithm, build the driving electric vehicle system model is established, the simulation for electric vehicle driving modes corresponding battery prediction, implementation based on the working condition of electric vehicle recognition and prediction of SOE is estimated.

Lead-acid storage seal The battery By the positive and negative plate, diaphragm and article, battery electrolyte slot and connecting the lead (or parts), exhaust valve and terminals, etcA, the main components of the battery1, the plate is the core parts of the storage battery is the "heart" battery, can be divided into positive plate and negative plate.

China's automobile starting lead accumulator The battery, according to GB/T5008 2-91 standards, divided into rubber fixed on the shell and plastic shell, plastic shell under stationary etcSeries single cell count: refers to the number of the single cell battery assembly contains, expressed with Arabic numerals.

The lithium batteryAdvantages: no memory effect, lighter in weightDisadvantages: high cost, current is small, not too full charge resistance (compared with nickel metal hydride)Lithium-ion batteries have a li-ion battery (rechargeable) and secondary li-ion battery (rechargeable), secondary lithium electricity divides Li - ion lithium ion batteries and Li - polymer lithium polymer battery。General digital camera usually use secondary li-ion battery (rechargeable) compared with Ni MH battery -, Ni - MH light in weight and volume energy density ratio is 48% higher Because of this, production and sales of lithium ion secondary battery are gradually more than more than Ni MH.

Electric car run for a long time, the battery is a bit not line, this time, change batteries for electric vehicles can be solved, it is much cheaper than change the electric bikes, when buy battery field packing and unpacking, be sure to see the factory date, anti-counterfeiting code, license, factory, such as parameters, in order to identify the old and new batteryBatteries are divided into new and special two kinds of after-sales service.

Quick charge as the most important technology of new energy vehicles development path, its range for alleviate anxiety, and reduce the charging time effect is remarkable, therefore many automakers and battery enterprises have become the market selectionAt the end of 2016 the new energy vehicles subsidies adjustment scheme, the quick charge type of pure electric bus is as a separate product segment, and give the detailed subsidy standard: according to the bus capacitance may obtain 3000 yuan/Kwh, at the same time, according to the "3 c to 5 c and 5 c - 15, 15 c + c" three grades of quick charge ratio respectively 0.
