Description

Production equipment for battery box of electric automobile

Technical Field

The utility model relates to a production facility of electric automobile battery case.

Background

Batteries for electric vehicles fall into two broad categories, batteries and fuel cells. The storage battery is suitable for pure electric vehicles and comprises a lead-acid storage battery, a nickel-metal hydride battery, a sodium-sulfur battery, a secondary lithium battery, an air battery and a ternary lithium battery.

The electric vehicles are slightly different according to different types. In a pure electric vehicle which is equipped only with a battery, the battery serves as the sole power source for the vehicle drive system. In a hybrid vehicle equipped with a conventional engine (or fuel cell) and a battery, the battery can play both the role of the main power source and the role of the auxiliary power source of the vehicle drive system. It can be seen that the storage battery plays the role of a main power source of an automobile driving system at low speed and starting, plays the role of an auxiliary power source at full-load acceleration, and plays the role of storing energy at normal running or deceleration and braking.

The battery pack of the electric automobile is formed by serially stacking a plurality of batteries. A typical battery pack has about 96 cells, and for lithium ion cells charged to 4.2V, such a battery pack can produce a total voltage in excess of 400V. Although the automotive power supply system considers the battery pack as a single high-voltage battery, charging and discharging the entire battery pack each time, the battery control system must consider the condition of each battery independently. If one cell in the battery pack has a slightly lower capacity than the other cells, its state of charge will gradually deviate from the other cells over a number of charge/discharge cycles. If the state of charge of this cell is not periodically balanced with the other cells, it will eventually enter a deep discharge state, resulting in damage and ultimately battery pack failure. To prevent this from happening, the voltage of each battery must be monitored to determine the state of charge. In addition, a means must be provided to allow the cells to be individually charged or discharged to balance the state of charge of the cells.

Lithium batteries are packaged in sealed, boxed containers to prevent air ingress, and are typically provided with a stainless steel casing and an aluminum alloy casing to prevent external damage. For example, tesla electric vehicles even employ titanium alloy fenders to prevent damage to the battery container during vehicle use, particularly in traffic accidents.
