The term high voltage is defined for DC voltages above 60 V and AC voltages above 30 V (ISO 6469-3, 2011). The reason for using high voltages in a battery pack comes from the basic law of physics: (10.1) P = V ⋅ I
10.1. Introduction The motivation for designing high-voltage (HV) batteries arises from the requirement for storing a certain amount of energy and power for a specific application while considering the limitations of the available technology on the market.
When applied the proposed DCR model to a commercial high voltage 4.45 V LiCoO2 pouch battery, the simulated results can well match with the experiments, implying the workable of this strategy. This paper shed light on guiding electrochemical parameters design, especially for high energy-density commercial batteries. 1. Introduction
Other components that are integrated into the battery housing are the pressure equalization element (see Section 10.2.4.1) as well as a device for condensate handling (see Section 10.2.4.2). A main function of the battery housing is the provision of the mechanical, thermal, and electrical interfaces to the vehicle.
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.
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
