Self-adaptive fast charging and conventional charging method and system for different batteries

Abstract

The invention discloses a self-adaptive fast charging and conventional charging method and system for different batteries, and the system comprises a charging pile, the charging pile is connected with a charging gun through a circuit, the charging gun is connected with a charging line and a communication line in parallel through a circuit, and the charging line and the communication line are connected with an intelligent flash charging lithium battery module in parallel through a circuit. The charging line and the communication line are connected in parallel with a special lithium battery switching module through a circuit, and the special lithium battery switching module is connected in series with a common lithium battery module through a circuit; through communication between the automobile battery BMS and the intelligent direct current charging pile, the intelligent direct current charging pile intelligently recognizes the voltage and current of the automobile battery, the charging pile adjusts the charging voltage and current according to the requirements of the battery BMS, intelligent adaptation with the automobile battery can be achieved, charging is more convenient, rapid charging can be achieved after adaptation with the voltage and current, and intelligent and rapid adaptive charging is achieved.

Description

technical field [0001] The invention relates to the field of battery charging, more specifically, to a method and system for adaptive fast charging and conventional charging of different batteries. Background technique [0002] In today's daily life and work, the use of electric vehicles is more common, and in driving, it is necessary to configure batteries for energy storage and energy supply, and most commonly used are lithium batteries and lead-acid batteries, and lithium batteries can be divided into fast Rechargeable lithium batteries and ordinary lithium batteries have different states and requirements. [0003] In daily use, it is necessary to configure a dedicated charger to charge the battery, but now the original factory can only adapt the power unit (motor), power battery and charger in advance, and label it as the manufacturer's standard battery and the original battery. Each charger has its own standard, and there are also universal chargers from third-party su...

Problems solved by technology

[0003] In daily use, it is necessary to configure a dedicated charger to charge the battery, but now the original factory can only adapt the power unit (motor), power battery and charger in advance, and label it as the manufacturer's standard battery and the original battery. Each charger has its own standard, and there are also universal chargers from third-party suppliers in the society. Each link is independent of each other. Charging safety involves the above four links. A large amount of charging is caused by a certain link being uncontrollable. Fire accidents, and for different batteries, the charging time and safety are different, which seriously restricts people's daily use. In order to solve the problem of how to charge traditional non-intelligent batteries with new smart charging piles, it is necessary to design a battery for different types and specifications. The intelligent conversion module of the battery is bound to the person and the battery at the same time. The user can use the certified adapter device to realize the normal charging without bringing the charger, and reduce the use or purchase of inferior chargers.
