Electric vehicle power battery system and electric vehicle

Abstract

The invention relates to the technical field of electric automobiles, provides a power battery system for an electric automobile and the electric automobile, and aims at solving the problems that the existing electric automobile is long in charge time, few in charge facilities, short in service life of a battery and short in driving mileage. The system comprises a controller, an aluminum-air battery pack, a first electric quantity collection module, a lithium-ion battery pack, a second electric quantity collection module and a direct-current to direct-current (DC / DC) module. The charging control of the battery system provided by the invention is relatively intelligent; and meanwhile, the charging rate is high.

Description

Technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a power battery system of an electric vehicle and an electric vehicle. Background technique [0002] At present, pure electric vehicles have received attention and development due to their many advantages such as zero emission of harmful gases, high energy efficiency, low noise and simple structure. [0003] Pure electric vehicles in the prior art generally use lithium iron phosphate or Li[Ni-Co-Mn]O 2 Ternary lithium-ion batteries, electric vehicles using this type of battery have long charging time, fewer charging facilities, short battery life, and short cruising range. If you want to increase the driving range, you can only increase the number of lithium-ion batteries, but at the same time it will greatly increase the curb weight of electric vehicles, reduce the vehicle's quality utilization factor, and increase the difficulty of vehicle manufacturing and use and maintenan...

AI Technical Summary

Problems solved by technology

[0003] Pure electric vehicles in the prior art generally use lithium iron phosphate or Li[Ni-Co-Mn]O 2 Ternary lithium-ion batteries, electric vehicles using such batteries have long charging time, few charging facilities, short battery life, and short cruising range

If you want to increase the driving range, you can only increase the number of lithium-ion batteries, but at the same time, it will greatly increase the curb weight of electric vehicles, reduce the quality utilization factor of vehicles, and increase the difficulty of manufacturing vehicles and the cost of use and maintenance.
