As Automotive OEMs Target Increasing Electrified Vehicle Range (=300 miles) And Decreasing Charge Time (=15min), What Are The Trade-Offs In System Design, Opportunities And Challenges? The battery is a key feature for both cost and performance, and its chemistry and cell levels are extensively discussed. At pack and module level (beyond the cell) there are huge material opportunities; a key part of this is how the cells are protected, connected and allowed to dissipate heat.

The most prevalent challenges continue to be based around thermal management, maintaining the temperature essential for performance; a challenge set to greaten with the rise of up to 350 kW fast charging on the horizon. With aggressive battery charging for vehicles come concerns of reduced life and temperature stability. This series takes a deep dive look at enabling materials and technologies, such as advanced thermal management and high voltage architectures, that are set to aid the charging gap and customer range anxiety.

BEV THERMAL MANAGEMENT INNOVATION

In Europe bringing forward the ban on the sale of new petrol and diesel cars to 2030 means that advancing efficiency benefits to existing battery technologies has never been more crucial.

Every manufacturer has their own methodology to thermally manage their batteries with no clear consensus on the most effective design. Companies like Tesla are set on their patented water-glycol coolant lines which “snake” their way between the cylindrical cells in the pack, whereas OEMs like Nissan and Toyota are committed to air cooling. Active cooling of batteries with fluids are effective, but these significant advantages come at the expense of weight, complexity and cost.

In addition to the more widely adopted technologies, there are other emerging alternatives such as immersion cooling and phase change materials, and these technologies are gaining traction. Practically no EV battery pack has the same design from the cell form (cylindrical, pouch, prismatic) to thermal management employed; typically air, liquid, or refrigerant in either an active or passive capacity. Immersion cooling is an emerging opportunity that we will look at over the webinar series, that is beginning to find market traction. The location of the TIM can also vary widely, and this is also something that we will explore in detail.

There are also numerous material considerations: through-plane conductivity, viscosity, adhesiveness, compressive strength, lifetime, and more. Then there are the factors of cost, application method, and the wider manufacturing impact.

Faced with the on-going restrictions that prevent us from meeting in person, once again WeAutomotive Group will deliver high-quality solution orientated content that addresses the key and current Battery Thermal Management innovation challenges – keeping the industry connected in an easily accessible, direct format.
