Electromobile battery pack capable of being quickly charged and quickly-charging method thereof

Abstract

The invention discloses an electromobile battery pack capable of being quickly charged and a quickly-charging method thereof. The electromobile battery pack capable of being quickly charged comprises a main control chip, a battery pack body and a main switch circuit. The main control chip is electrically connected with the battery pack body, and the main switch circuit is connected with the battery pack body. Breakover or disconnection of the battery pack body is controlled according to a signal of the main control chip. The main control chip is in electric connection with a voltage detecting circuit and an electric current detecting circuit. The voltage detecting circuit is used for detecting the battery voltage of the battery pack body, and the electric current detecting circuit is used for detecting electric currents for charging and discharging of the battery pack body. The voltage and electric current information collected by the voltage detecting circuit and the electric current detecting circuit is subjected to logical analysis through the main control chip, and thus breakover or disconnection of the main switch circuit is controlled. According to the electromobile battery pack capable of being quickly charged and the quickly-charging method thereof, by combination of single-chip microcomputer technology and battery charging and discharging protection technology, batteries are capable of being quickly charged, safe and reliable. Charging efficiency is greatly improved, and charging time is short so as to meet the demands of users about charging time.

Description

technical field [0001] The invention relates to the technical field of charging electric vehicle battery packs, in particular to a rapidly chargeable electric vehicle battery pack and a fast charging method thereof. Background technique [0002] In the current society, the emergence of electric vehicles has solved the problem of people's travel convenience, but due to technical problems in the battery pack that powers the electric vehicles, it takes about 8 to 20 hours for slow charging, which affects the convenience of customers. ; Fast charging technology also needs 4 to 8 hours, the time is still too long, still can not meet the requirements of some customers for charging time. [0003] In addition, the existing electric vehicle battery packs, no matter the existing lithium battery packs or lead-acid battery packs, the ratio of charging current to battery capacity is still not large enough to meet customers' requirements for fast charging time.
