The invention provides a novel energy car, and the car comprises a charging socket, a charging circuit, a battery pack, a battery voltage comparison chip, and a reference voltage chip. The charging socket comprises a first charging positive end, a first charging negative end, and a first control end. The positive output end of the charging circuit is connected with the positive electrode of the battery pack and the in-phase input end of the battery voltage comparison chip. The inverted input end of the battery voltage comparison chip is connected with the output end of the reference voltage chip. The output end of the battery voltage comparison chip is connected with the first control end, and the positive input end of the reference voltage chip is connected with the in-phase input end of the battery voltage comparison chip, the positive input end of the charging circuit and the first charging positive end. Through a relay, the connection between a voltage transformation circuit and the charging circuit is cut off after a battery is charged fully, thereby enabling the charging circuit to be completely cut off, preventing the battery from being charged after the battery is charged fully, and avoiding an overcharging conditions.
Description
technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a new energy vehicle. Background technique [0002] New energy vehicles are receiving more and more attention from the country because of environmental protection and energy saving. Electric vehicles account for a very large proportion of new energy vehicles. The body of an electric vehicle contains a battery pack for driving the wheels. Existing electric vehicles have a circuit to prevent overcharging, but the existing circuit is fully charged, the charging circuit does not output, after a period of time, the battery voltage drops slightly, the charging circuit will recharge, This creates a situation of floating charging, which can easily lead to a reduction in the life of the battery. Others use microcontrollers for intelligent control, but there are reliability problems in microcontrollers. Microcontrollers may fail due to electromagnetic interference, and the use...
