Problems solved by technology

Among them, pure electric vehicles are vehicles driven purely by electricity. The technology is relatively simple and mature, but its current shortcomings are short mileage and slow charging speed.
[0004] The existing charging strategy of the power station will cause the lithium-ion battery system to be stored under the 100% SOC (full charge state) calibrated by the battery management system after it is fully charged. At this moment, the real state of charge of the lithium-ion battery reaches at least 95%. above
Such storage conditions will accelerate the degradation of lithium-ion battery performance and shorten the service life of lithium-ion battery systems

Abstract

The invention provides a charging method and charging device executed in a battery replacing facility, and a far-end server. According to one aspect of the invention, the charging method comprises thefollowing steps of: determining a charging mode for a battery according to the charging starting time and / or the number of batteries of which the state of charge is higher than or equal to a first threshold value in the battery replacing facility; and charging the battery by using the determined charging mode until the state of charge of the battery is increased to the first threshold value and then the to-be-charged battery is allowed to stand still without directly increasing the state of charge of the to-be-charged battery to a full state of charge. Therefore, the lithium ion battery system can be effectively prevented from being stored in a high-charge state, and the service life of the lithium ion battery system is prolonged.

Description

technical field [0001] The present invention relates to a charging strategy of a power exchange facility, in particular to a charging method, charging equipment and a remote server implemented in a power exchange facility. Background technique [0002] In recent years, with the need to solve the energy crisis and the government's policy support, the new energy vehicle industry has shown explosive growth. Among them, pure electric vehicles are vehicles driven purely by electricity, and the technology is relatively simple and mature, but their current shortcomings are short cruising range and slow charging speed. [0003] At present, major lithium-ion battery manufacturers are working hard to increase the energy density of batteries, and the design of lithium-ion battery systems is also taking a lightweight route. These can make more electricity per unit volume or weight, thereby improving the cruising range of the vehicle . For the problem of slow charging speed, since the ...
