Battery-pack thermal
Gap fillers and pads that connect cells and modules to cooling plates while tolerating vibration, thermal cycling, and the crush and nail-penetration loads batteries must survive.

SOLUTIONS · ELECTRIC VEHICLES
Thermal systems for the electric powertrain.
Battery-pack cooling, motor, and power-electronics thermal materials, the full thermal stack for the electric powertrain, backed by charging and safety infrastructure from the HeTone Group.
The Challenge
Three thermal problems, one chassis.
An EV is three thermal problems in one chassis: a battery pack that has to stay in a tight temperature window, a traction motor that runs hot under load, and power electronics switching at high frequency. Each needs a different material set, and all of them have to meet automotive reliability and safety requirements.
HeTone supplies battery gap fillers, motor and inverter interface materials, and coolants from licensed lines, qualified across the powertrain so the whole system is specified consistently. Through HeTone Green Energy, the Group also deploys charging infrastructure, energy storage, and EV fire-safety solutions, covering the full EV value chain from component to field.
