In the eighteenth instalment of our Tech Tuesday Series, we take a bite-sized look at what goes into the technology behind our battery tech, with
At Xerotech we are continuously innovating. We want to be the best in the world at what we do, so we will never stop investing in people, quipment, and processes, making sure that we create the most advanced technology possible.
Fire safety and thermal performance is everything, especially if you are a mile underground in 45° heat. We’re exceptionally good at controlling the temperature of our batteries. This is undoubtedly important for industrial applications where you could be operating in arctic or desert conditions. Temperature is the enemy of battery lifetime. Every 10 degrees over 25 C you basically halve battery lifetime.
We can keep the pack at its optimum temperature, extending lifetime, and we can fast charge it harder and for longer than anyone else on the market.
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 Xerotherm’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. The combination of fire-retardant thermally insulating foam and an extremely conductive thermal management system results in highly robust and safe battery systems.
Every module used in Xerotech’s Hibernium™ platform batteries is equipped with our proprietary hybrid Thermal Event Suppression system.
Batteries used in mobile applications need to stay safe under all conditions. Collisions, catastrophic crush, external body penetration and other accidents can cause battery cells to undergo thermal runaway. Battery fire is an unacceptable failure mode which is why we equip all our batteries with Passive Propagation Resistance and Suppression systems as standard.
Xerotherm® safety technology is designed to stop even the most violent thermal runaway events within seconds, preventing propagation and extinguishing fires where they occur.
The Battery Management System serves as a complete solution for monitoring and control. Xerotech’s BMS is built on a highly configurable platform, allowing it to support a wide variety of architectures, and driving lower cost and a faster time to market when compared to peers.
Standard features include:
Voltage and current monitoring, temperature monitoring, high voltage, isolation monitoring, cell balancing, short circuit protection, high-voltage interlock, crash detection, moisture monitoring, leak detection, contactor control, functional safety, diagnostics (CAN).

Direct interconnection of modules and optimized parallel flow paths enable significantly increased flow rates resulting in lower cross-pack thermal gradients and differential aging of the battery.
Thermal management deeply affects cycle life and ultimately TCO.
