6 FAQs about [Chassis battery pack energy storage]

Can a car's battery pack be used for energy storage?

But for Greenhalgh and his collaborators, the more promising approach is to scrap the battery pack and use the vehicle’s body for energy storage instead. Unlike a conventional battery pack embedded in the chassis, these structural batteries are invisible.

What is a structural battery pack?

The structural battery pack is a kind of electric vehicle battery that is cleverly designed to efficiently fit into the car. It is part of the vehicle’s chassis, as the battery pack acts as a structural part of the whole car. Seats are directly mounted to the battery pack itself.

Why is battery pack box structure important?

Abstract. The power battery is the only source of power for battery electric vehicles, and the safety of the battery pack box structure provides an important guarantee for the safe driving of battery electric vehicles. The battery pack box structure shall be of good shock resistance, impact resistance, and durability.

Where is the battery pack box arranged?

The battery pack box of the target vehicle is arranged under the chassis, below the floor of the passenger compartment, disassembled from the electric vehicle. The appearance structure of the box is shown in Fig. 3. After removing the upper cover, the battery pack module is presented, and the structure is shown in Fig. 4.

What is a power battery pack box?

The power battery pack box is the core component of the BEV. The power battery pack provides energy for the whole vehicle, and the battery module is protected by the outer casing. The battery pack is generally fixed at the bottom of the car, below the passenger compartment, by means of bolt connections.

Which electric vehicles use a structural battery pack?

There is only one vehicle that uses a structural battery pack. It is the Texas-made 2022 Tesla Model Y. Giga Berlin will also start producing electric vehicles with structural packs in the coming months. Tesla will improve its existing EVs such as Model 3 and Model S/X with the new pack in the near future.
