To address these challenges, battery module interconnects can integrate flexible sections that absorb vibrations, thermal expansion or any micromovements. They can also incorporate technology to make assembly easier, through direct connectors that avoid screws and allow for position tolerance.
The packaging design presented by US Patent No. 8663824 also demon-strated how a central battery pack member can be employed to further separate the right and the left compartments in addition to providing a channel for connecting power and data lines. In the design, module mounting ange of the battery module is
Each beam engages one of the four sides of the battery pack. Positive connection between frame and the battery pack is maintained through tensioning bolts. The arrangement uses two types of damping pads, at and L-shaped, to absorb vibration and prevent movement of the modules with respect to one another along the Z-axis.
The main target of the battery pack design is to reduce the costs of the individual components and increase the energy density on a system level without affecting the safety and lifetime. 10.1. Introduction
The primary components of a battery pack are the battery modules. The battery modules contain the lithium-ion cells and are usually designed in such a way that their module terminal voltage is below 60 V, and hence they can be handled without additional and expensive safety precautions (see Section 10.2.1).
The housing of a battery pack also contains all interfaces to the vehicle, such as the HV plugs, communication, and cooling interfaces (see Section 10.2.4). As an example, Figure 10.2 shows a flat battery pack of an EV. It consists of 18 battery modules that are separated by seven cooling plates.
As for PHEVs and especially BEVs the battery pack accounts for the biggest part of the weight of the whole vehicle, the battery housing is designed in strong interaction with the design of the body of the car.
To address these challenges, battery module interconnects can integrate flexible sections that absorb vibrations, thermal expansion or any micromovements. They can also incorporate technology to make assembly easier, through direct connectors that avoid screws and allow for position tolerance.
