Problems solved by technology
Since the charging time is much longer than that of fuel vehicles, even if it is advertised as fast charging, it will take at least 1 hour or more. Therefore, electric vehicles deliberately pursue the mileage of a single charge in order to reduce the number of charging, but it is impossible for any vehicle to increase the battery infinitely. group capacitance

The invention discloses an optimized electric vehicle power source and an electric vehicle power source working method. The power source comprises a redundant power supply system and a spring power energy storage system, wherein the redundant power supply system comprises a central management system, battery management systems and battery modules, the central management system uniformly controls and distributes all the battery modules, a corresponding battery management system independently controls each group of batteries to monitor and protect each battery in real time, and the power of thebattery modules independently satisfies rated current of a motor. According to the power source and the method, all limits of the quick charging performance, a charging pile and large current on battery packs are broken, the charging time is close to the required time for oil filling of a fuel vehicle, an electric vehicle can run for a long distance like the fuel vehicle and does not need to simply pursue a full-power endurance mileage, and the redundant power supply system improves the management of the battery packs, reduces the cost, and improves the safety.
Description
technical field [0001] The invention relates to a working method of a power source of an electric vehicle, in particular to an optimized power source of an electric vehicle. Background technique [0002] Whether it is to purify the human living environment or make good use of the earth's natural resources, it is time to pay attention. The replacement of fuel vehicles by electric vehicles is also an inevitable trend in the development of science and technology. It also represents the future development direction of the automobile industry. After more than ten or twenty years of development, electric vehicles have gradually entered the stage of market application. Although the power source of electric vehicles is mainly lithium-ion batteries based on lithium iron phosphate system and ternary lithium system, it also presents a flourishing , The diversified development of other power sources with their own characteristics. [0003] However, compared to fuel vehicles with a hi...
