6 FAQs about [Structure of high voltage battery pack]
What is the main target of battery pack design?
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
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 are HV battery packs?
HV battery packs for battery electric vehicles (BEVs) are characterized by high energy densities and high energy contents with low power densities. Figure 10.1 shows a schematic illustration of a battery pack and its components, which are necessary to fulfill the vehicle requirements. Figure 10.1.
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.
What are the design requirements for a battery pack?
An important design requirement is the electrical isolation of the HV components of the battery pack. The HV components include the cell, module, or battery pack terminals and any conductive parts attached to them.
What are the standards for HV battery pack design?
Thus, relevant literature is published in terms of norms and standards as well as patents. An important standard for HV battery pack design is the ISO 6469 “Electrically Propelled Road Vehicles—Safety Specifications,” especially ISO 6469-1 (ISO 6469-1, 2009), and ISO 6469-3, which may serve as a starting point for interested readers.
