Liquid Immersion Cooling for Electric Truck Batteries

Electric Truck Battery Cooling

The electrification of cars is well and truly underway, however the same cannot be said for electric trucks. Whereas car manufacturers face legislation banning the production of new vehicles of new internal combustion engine (ICE) vehicles after 2030, no such legislation exists specifically for trucks, though there is the ‘Fit for 55’ package, introduced by the European Commission (EC) in 2021. This refers to the EU’s target of reducing net greenhouse gas emissions by at least 55% by 2030. This will likely push truck manufacturers to develop emission-free vehicles. Manufacturers will also face pressure from customers who wish to reduce their carbon footprint and meet corporate sustainability targets.

Electrifying truck-fleets will present many challenges to manufacturers:

  • Vehicle range

  • Charging rates

  • Costs

Millions of trucks are relied on across continents, making it no easy feat to upgrade vehicle fleets. As with electric cars – range, charging rates and costs all present challenges. Trucks travel many miles across borders, so they require as much range as possible and the ability to charge quickly conveniently.

Thermal management of batteries can overcome some of the issues faced by the truck manufacturers. If batteries are kept at ideal temperatures, their capacity increases and so does vehicle range. Overheating becomes less likely, and this reduces the risk of degradation, which increases battery life. One way to achieve optimal temperatures is by immersing batteries in a dielectric liquid, such as MIVOLT. MIVOLT enables batteries to take higher power transfers without overheating, which facilitates super-fast charging. Other benefits include:

  • Lower costs (complexity of cooling equipment can be reduced)

  • Maximum performance

  • Improved safety (MIVOLT is readily biodegradable and non-toxic)
