Description
Technical field [0001] The invention relates to the technology of electric vehicle accessories, in particular to a battery voltage and temperature acquisition system. Background technique [0002] With the development of social science and technology, electric vehicles are more and more popular with people due to their advantages of high environmental protection, energy saving, light weight, convenience and low price, and their applications are becoming more and more common. [0003] Among them, the power source of electric vehicles is electric energy, so a battery pack composed of lithium batteries is usually selected as the energy storage unit of electric vehicles. Among them, lithium batteries have the characteristics of high energy density, small size, and high power density. The use of lithium batteries as energy storage units has become the mainstream development direction of today's electric vehicles. In practical applications, because lithium batteries are sensitive to vol...
