Description
Technical Field
The application relates to the technical field of decommissioning of power batteries, in particular to a decommissioning device and a decommissioning method for power batteries.
Background
With the rapid development of new energy electric automobile industry in China, the problem of processing the power battery for the electric automobile after retirement is increasingly prominent. It is expected that the cumulative size of retired power cells will exceed 20GWh by 2020. If the retired power battery is improperly treated and is randomly placed or discarded, not only can environmental impact and potential safety hazard be brought to the society, but also serious resource waste can be caused.
The retired power battery cannot be used on the power automobile continuously due to capacity attenuation, but still has high residual capacity and equivalent utilization value. The method is an important link in the recovery and utilization process of the power battery.
Common Bus-bar connections can be divided into two forms, welding and bolting. The bolt fixing mode is easy to install and disassemble, but in long-term running jolt of the electric automobile, the bolt is easy to loosen and causes poor contact and hidden trouble, and meanwhile, the bolt fixing mode is not beneficial to large-scale production, and the bolt fixing mode gradually exits from the application of the main technical route. The current mainstream connecting process is welding, the connecting mode can effectively avoid the problem that a connecting piece is loosened in bumping during long-term operation, but the difficulty of disassembling and recombining the power battery during retirement and reuse is also increased.
Therefore, at present, for the treatment of the Bus-bar of each battery in the retired power battery, two modes of laser and mechanical rotation are generally adopted for cutting and disassembling.
Due to the high cost, complexity and limitation of a laser cutting mode, the disassembly work of each mechanism and unit during the echelon utilization of the retired power battery is seriously restricted. Therefore, in many of the mechanisms and units, semi-automatic or manual mechanical rotary cutting is employed, and cutting and dismantling are performed by using mechanical rotary tools (electric/pneumatic) such as a grinder and an angle grinder. The method has low cost and strong flexibility, but has high requirements on the technical level and practical experience of operators, needs to be adjusted and controlled in real time according to the actual situation on the spot, and is inconvenient to operate. Meanwhile, the mechanical rotary tool has larger rotary inertia, is not easy to control and careless in operation, so that the grinding wheel or the steel saw blade is easily damaged and flies off, and certain potential safety hazards exist.
