Vehicle starting power source

Abstract

The invention relates to a vehicle starting power source. An accumulator system of the starting power source provided by the invention is composed of a winding type lead-acid battery pack and a pole plate type lead-acid battery pack through parallel connection. The vehicle starting power source provided by the invention can exert the advantages of high discharge rate of a winding type lead-acid battery to greatly increase cold start current CCA as well as slow attenuation of the winding type lead-acid battery and can exert the advantages of cheap price and high volume energy density of a pole plate type lead-acid battery, so that the service life of the accumulator system is greatly prolonged, the reserve capacity loss of the accumulator system is relatively small, and the cost increase is less; and the vehicle starting power source has good comprehensive performance and cost performance advantages.

Description

technical field [0001] The invention relates to a starting power supply for various internal combustion engine vehicles. Background technique [0002] Various internal combustion engine vehicles have become people's daily means of transportation and transportation, such as passenger cars and passenger cars, trucks for transporting goods, etc. The starting of these vehicles is all realized by the starting power mainly composed of batteries, the starting motor is driven by the starting power, and the engine is driven by the motor to work. When the on-board generator stops working, the starter power supply is also responsible for supplying power to the on-board electrical devices, such as lights, audio, electric doors and windows, etc. [0003] The core component of the starting power supply is the battery pack. In the technical schemes adopted by the starting power supply of various vehicles, one battery pack is used to simultaneously complete and shoulder the dual functions...

AI Technical Summary

Problems solved by technology

However, the cost of wound lead-acid batteries is much higher than that of plate-type lead-acid batteries, and its volumetric energy density is much lower than that of plate-type lead-acid batteries. Too high, hindering its promotion and use

[0006] People have also developed a plan to use lithium-ion battery packs instead of lead-acid battery packs as starting power, but because lithium-ion batteries are not as reliable as lead-acid batteries, and more importantly, their low-temperature charging performance problems have not been well resolved, so use Lithium-ion battery as a starting power solution is just an exploration
