6 FAQs about [Illustration of the internal structure of the battery pack high voltage box]

What is the electrical design of a battery pack?

The electrical design of the battery pack is associated with fundamental electrical elements. These elements are: Busbars, Contactors, Fuses, pre-charge resistors, current sensors, HV (High Voltage) and LV (Low Voltage) Connectors, and wiring harnesses. This will cover: For all of these components we need to consider:

How does a battery pack design work?

Extensive calculations are then carried out to determine the battery pack's energy, capacity, weight, and size. The design involves grouping cells into modules for easier management and protection, while also incorporating cell holders to enhance stability and minimize vibrations.

What are HV battery packs?

What are the components of a battery pack?

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).

What is a HV battery junction box?

Careful consideration needs to be taken: The HV battery junction box brings together the measurement, control and connections of the battery high voltage (HV) system. Therefore, it would normally contain: By short circuit we mean an electrical short circuit, a very low resistance path between the positive and negative sides of the cell or cells.

What is the housing of a battery pack?

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.
