Thermal Management

Thermal Management

Xerotech’s patented integrated thermal management-passive propagation resistance technology represents a complete step-change battery module design.  Our inflatable ultra-thin polymer duct has been nano-engineered for exceptionally high thermal conductivity while also being incredibly thin – an essential element for low thermal resistance. 

The polymer duct is completely supported by the foam matrix, making it impossible to burst or be punctured. Our solution offers 17 times higher heat transfer than conventional side-wall cooling technology.

The risk of thermal propagation is virtually eliminated with Xerotech’s proprietary module design by using a specially engineered fire-retardant structural foam. It’s 85% lighter than solutions used by leading electric vehicle manufacturers that are household names.

Direct interconnection of modules and optimized parallel flow paths enable significantly increased flowrates resulting in lower cross-pack thermal gradients and differential aging of the battery. 

Why Thermal Management Matters?

Thermal Management deeply affects cycle life and ultimately TCO

Rule of Thumb

  1. You cannot charge below 0°C Catastrophic failure mode
  2. Every 10°C above 25°C halves battery life
