Embodiment Construction

[0024] It should be noted that, according to the principle of battery energy storage and discharge in traditional technology, the power battery pack mainly realizes the function of charging and discharging through the internal chemical fuel. In the traditional technical field, power batteries are divided into the following types according to the type of manufacturing materials: Lead-acid batteries, nickel-cadmium batteries and nickel-hydrogen batteries, etc., the decommissioned power batteries in the present invention include all different types of power batteries in the technical field; when the power battery is charged or discharged for a long time, the chemical inside the power battery The fuel (such as hydrocarbon or ethanol) realizes the mutual conversion between chemical energy and electrical energy through oxidation-reduction reaction under the action of the catalyst; in the initial stage, due to the high concentration of chemical fuel inside the power battery, the extern...

Abstract

The invention belongs to the technical field of electrochemical energy storage, and provides a charging and discharging control method and a charging and discharging control device for a retired powerbattery set. The retired power battery set comprises more than two retired power battery packs, and the charging and discharging control method comprises the following steps: acquiring operation parameters of each retired power battery pack; classifying and summarizing the operation parameters of the retired power battery packs to obtain battery information of the retired power battery packs; performing power-on start-up and power-off time sequence control on the retired power battery packs according to the battery information; and after the retired power battery packs are powered on and started up, carrying out discharging time sequence control and charging time sequence control respectively on the retired power battery packs according to the battery information so as to realize the balanced discharging and charging process of the retired power battery packs. Therefore, the problem that the retired power battery packs cannot be recycled due to the fact that the charging process and the discharging process of the retired power battery packs cannot be controlled in the traditional technology is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of electrochemical energy storage, and in particular relates to a charging and discharging control method for a decommissioned power battery pack and a charging and discharging control device for a decommissioned power battery pack. Background technique [0002] As people's awareness of environmental protection increases, renewable energy products have been widely used. Taking electric vehicles as an example, electric vehicles need to consume a lot of electricity during operation. However, electric vehicles have limited energy storage capacity and limited service life. , when the electric vehicle runs for a long time, the power battery inside the electric vehicle will gradually lose its energy storage capacity due to the long-term charging and discharging process, so users need to replace the power battery in the electric vehicle regularly, then people use electric vehicles Many decommissioned power battery ...
