Description

Technical Field

[0001] The invention relates to the technical field of transport slings, in particular to a transport sling used for off-line inspection and packaging of automobile batteries. Background Art

[0002] Electric vehicle batteries are divided into two categories, storage batteries and fuel cells. Storage batteries are suitable for pure electric vehicles, including lead-acid batteries, nickel-metal hydride batteries, sodium-sulfur batteries, secondary lithium batteries, air batteries, and ternary lithium batteries. Fuel cells are specifically used in fuel cell electric vehicles, including alkaline fuel cells (AFC), phosphoric acid fuel cells (PAFC), molten carbonate fuel cells (MCFC), solid oxide fuel cells (SOFC), proton exchange membrane fuel cells (PEMFC), and direct methanol fuel cells (DMFC). The battery pack of an electric vehicle consists of multiple batteries stacked in series. A typical battery pack has about 96 cells, and for lithium-ion batteries charged to 4.2V, such a battery pack can produce a total voltage of more than 400V. Although the car Power System Treating the battery pack as a single high-voltage cell, the entire pack is charged and discharged at a time, but the battery control system must consider each cell independently. If one cell in the pack is slightly less than the others, then over multiple charge / discharge cycles, its state of charge will gradually deviate from the others. If the state of charge of this cell is not periodically balanced with the others, it will eventually enter a deep discharge state, causing damage and ultimately battery pack failure. To prevent this from happening, the voltage of each cell must be monitored to determine the state of charge. In addition, there must be a device to allow the cells to be charged or discharged individually to balance the state of charge of these cells.
