Battery Thermal Management

Tremendous investments are being made in electrified vehicles and batteries to meet government targets and reduce vehicular emissions. Regulations and incentives in China and California as well as other regions are driving a need for more and higher levels of vehicle electrification. Vehicle manufacturers and battery suppliers around the world are making substantial investments in electrical energy storage technologies to meet regulations economically. The automotive manufacturers’ mixes of electrified technologies and global footprint are driving different battery configurations and thermal management designs. One key to improving both battery performance and reducing cost in improved thermal management.

Different electrical energy storage technologies are being applied for various powertrain types, since thermal challenges vary greatly depending on a powertrain’s mission. These technologies may add value at relatively low cost, for example when power delivery characteristics are improved to increase brake energy recuperation. Thermal management systems are also rapidly evolving to optimize value: cost versus performance in terms or power, energy, mass, and package density. In order to contain costs, redesigned components and system integration are necessary.

This brief will examine global OEM and supplier electrical energy storage thermal approaches. ITB’s research includes market, technology and economic value analyses to identify key thermal management trends, strategies, and priorities. The research incorporates feedback from Asian, European, and North American OEMs and suppliers. Thermal technology analyses cover vehicle architectures as well as battery specific alternatives. Key points of the research include:

  • Evaluating and prioritizing battery thermal challenges and system value across powertrains
  • Technology trends and strategies for leading OEMs and suppliers
  • Market trends and projections for electrified powertrains
  • Regulations, incentives, and their effects on vehicle and technology commercialization

Analysis includes the latest competitive, market, and technology trends through September 2018. The brief will be available in both PDF and hard copy formats.
