Lithium battery management system based on parking air conditioner

Abstract

The invention discloses a lithium battery management system based on a parking air conditioner. The lithium battery management system comprises the following two aspects: 1 a working stage; and 2 a main control strategy. A lithium battery is used, the designed lithium battery management system serves as a technical support, and the system is designed to be a starting and parking air conditioner integrated battery which directly replaces an original vehicle lead-acid storage battery. Therefore, the defects that a traditional lead-acid storage battery is not environmentally friendly, poor in low-temperature performance, short in cycle life, low in energy density and intolerant to large-current charging and discharging are effectively overcome, meanwhile, the management system improves the scheme that the lithium battery only supplies power to the vehicle-mounted parking air conditioner in the prior art, charging of the lithium battery does not need the help of an original vehicle-mounted generator, the system is simple, and the number of design links is small, so that fault points prone to occurring are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of parking air conditioners, in particular to a lithium battery management system based on parking air conditioners and a method for using them. Background technique [0002] The parking air conditioner is a kind of air conditioner in the car. It refers to the continuous operation of the air conditioner with the DC power supply of the car battery (12V / 24V / 36V) when parking, waiting and resting. Equipment that is regulated and controlled to fully meet the comfort cooling needs of truck drivers. In 2019, the production and sales of on-board parking air conditioners for commercial vehicles are about 800,000 sets, so the demand for batteries for parking air conditioners in the market has soared. [0003] There are three solutions to the current demand for this type of battery: [0004] First, continue to use lead-acid batteries, just simply increase the capacity of the battery [0005] Disadvantages: (compare...

AI Technical Summary

Problems solved by technology

[0010] The technical problem solved by the present invention is to overcome the problems that the prior art batteries for parking air conditioners are not environmentally friendly, have poor low-temperature performance, short cycle life, low energy density, cannot withstand high current charging and discharging, complex systems, and many design links. Provides a lithium battery management system based on parking air conditioners due to defects such as increased failure points
