Abstract:

The platformization development of vehicles and the corresponding systems is the consensus and important technology trend of the new energy vehicle industry， which is beneficial for planning each project systematically， sharing more systems and saving the cost. It is necessary for platformization development of battery systems based on vehicle platforms to clarify the relevant variables of vehicles and batteries， which mainly include the space， the weight， the mileage， the power consumption， the power performance of the vehicle， and the size， the weight， the energy， the power property of the battery. In this paper， the development of the battery system of a certain hybrid-vehicle platform is chosen as the case， where the platform solution including two or three types of cells is proposed via summarizing the distribution and boundary of each variable. Moreover， the bandwidth design of the series of the cells and the Y dimension of the pack is also proposed to make it compatible with 16 vehicle types. This study provides the basic reference of strategies for the development of battery solutions for various vehicle platforms of the industry in the future.

Key words: vehicle platforms, power batteries, platformization
