When it comes to developing electric cars that will be fit for the market, the integration of the energy storage systems is a big challenge for the car designers. First of all, the battery housing should make optimum use of the available installation space, in addition, lightweight design and function integration are important features, and on.
How to evaluate battery system frame topology?
Three main steps to evaluate the battery system frame topology. Firstly, various outer profiles were created using the GHT topology optimization methods developed by Ortmann . The method is used to find feasible profile structures balancing both the crash as well as the crush test requirements.
What factors affect the design of a high-voltage battery system?
In addition, different types of electric vehicles have different requirements that greatly affect the design of a high-voltage (HV) battery system, including its internal components, . Next to interior components, also size and shape requirements of components from cellmodule, mechanics, cooling, or electronics need to be adapted adequately.
What are the design variables of a battery system?
The design variables are mathematically defined as follows: x1 = Share of battery module installation space within the overall battery system installation space in the x-direction. x2 = Share of battery module installation space within the overall battery system installation space in the y-direction.
According to European regulations (default): 100 kN . Energy requirement that the battery system must be able to safely absorb (depending on the crash test, vehicle weight, sill, material, ). Mode 1 (Default): Only aluminum. Mode 2: Only steel. Mode 3: Internal optimization between aluminum and steel depending on feasibility, cost, or weight.
What is the evolution of electric vehicle chassis design?
The evolution of electric vehicle chassis design focuses on maximizing the benefits of electric driven. Lightweight materials, strategic placement of battery components, and aerodynamic enhancements are integral aspects of modern electric vehicle chassis.
Are battery pack packaging efficiency based on crash performance?
Uerlich et al. analyze battery pack packaging efficiency based on crash performance considering energy absorption from cell to system level . Arora et al. summarized mechanical design challenges and strategic placement techniques for optimal battery pack design .
