Problems solved by technology

If you need to use an external charger to charge the lithium battery of an electric vehicle, there is no system for directly charging the lithium battery of an electric vehicle by connecting the car cigarette lighter; from another perspective, it is hoped that the lithium battery of the electric vehicle can be used to charge the lead-acid battery of the car There is no such interface for battery life

Abstract

The invention discloses a bidirectional mutual charging system used for a lithium battery with an about 24V voltage and a lead-acid battery with an about 12V voltage. When a traditional small car carried with the about 12V lead-acid battery and an electric power-assistant vehicle with the about 24V lithium battery form a ''partner'' relation, through a cigar lighter port, a vehicle-mounted 12V voltage is used to charge a 24V electric vehicle lithium battery; and conversely, through the cigar lighter port, the 24V electric vehicle lithium battery is used to charge a vehicle-mounted 12V lead-acid battery.

Description

technical field [0001] The invention belongs to the field of new energy, and more specifically relates to a two-way mutual charging system for a lithium battery with a voltage of about 24V and a lead-acid battery with a voltage of about 12V. Background technique [0002] 24V voltage lithium battery is the standard working voltage of many lithium electric vehicles (such as some electric two-wheeled scooters and electric scooters) on the market, while the cigarette lighter interface of ordinary household cars is 12V voltage. Many portable electric vehicles use 24V lithium batteries, which are easy to carry and keep in a family car as a car companion. In particular, the lithium battery packs of some electric vehicles can also be disassembled from the electric vehicle, making it easier to place them in a family car. [0003] Currently, electric mopeds and cars do not have a mutual charge interface. For example, when the car is expected to continue to provide air conditioning, ...
