Description
Technical Field
The invention belongs to the technical field of energy storage, and particularly relates to a novel power battery cascade utilization PACK.
Background
In recent years, with the rapid development of electric vehicles, the scale of power batteries for electric vehicles has been gradually increased. Because the electric automobile has high energy requirement on a battery system, the energy of a single battery can not meet the use requirement of the electric automobile, and when the power battery is applied to the electric automobile, the power battery is used on the automobile in a grouping mode, namely, the single batteries form a battery pack in a serial-parallel connection mode, are fixed in a battery box, and are then used on the electric automobile. At present, the power battery specification for the electric automobile has no unified standard, each power battery manufacturer uses own battery specification, and the battery box is specially developed for realizing battery grouping for power batteries with different specifications.
The electric automobile has higher performance requirements on the power battery, and when the performance of the power battery is reduced to a certain degree (the capacity is reduced to 70-80% of the rated capacity), the power performance, the driving range and the safety performance in the running process of the electric automobile are ensured to be replaced. Batteries retired from the electric automobile still have higher residual energy, and the batteries are screened and recombined, so that the batteries can be possibly applied to occasions with relatively good working conditions and relatively low requirements on battery performance, and the gradient utilization of the power batteries is realized. However, after the power battery is used for a long time, the performance difference between the batteries is obviously increased besides the performance reduction of the batteries, and some batteries possibly have larger potential safety hazards and do not have the value of gradient utilization, so that the retired batteries need to be screened and assembled again before gradient utilization is carried out. Because the battery specifications produced by different manufacturers are different, the original battery boxes are used for a long time, the mechanical performance is reduced, the box body is deformed and the like, and most of the battery boxes cannot be reused after the battery pack is disassembled, so that the battery boxes for battery groups are specially designed and processed for batteries with different specifications when the battery boxes are used in a echelon manner, the cost of the echelon utilization of the power battery is greatly increased, meanwhile, compared with a new battery, the value of the retired power battery is greatly reduced, and if a lot of investment is additionally increased in the process of the echelon utilization, the economy of the echelon utilization of the power battery is greatly reduced.
At present, the power batteries in the market are rarely used in a cascade manner, and most of the power batteries are developed based on brand new power batteries. Most of the retired power batteries have the phenomena of damage, bulge deformation and the like of an outer insulating shell, and the insulation and fixation scheme of the existing PACK products can not meet the requirement of the retired power battery reorganization PACK. Therefore, in the face of the current situation of the power battery retirement market environment and resource shortage, there is an urgent need to develop PACK products capable of meeting the requirement of retirement power battery recovery and echelon utilization.
