The German manufacturer has developed a coolant for fuel cells as well as a special transmission fluid solely for electric vehicles
Ulm, Germany—LIQUI MOLY has developed a coolant for fuel cells as well as a special transmission fluid solely for electric vehicles (EVs). Both are available now.
“This is just the beginning of what we have in the pipeline,” said David Kaiser, head of Research and Development at LIQUI MOLY.
Although the number of conventionally powered vehicles will continue to far exceed that of alternative drives in the coming decades, LIQUI MOLY stated it is preparing for the mobility turnaround. “There will generally be a mix of different drive concepts,” Kaiser said. “Every vehicle and every manufacturer has different requirements. Our research ensures that we meet all approvals and requirements and, at the same time, deliver the highest quality.”
Coolants for electric vehicles in particular have to meet extreme requirements. The Fuel Cell Coolant FCF 20 by LIQUI MOLY based on ethylene glycol, combined with non-ionic additives, exhibits very low electrical conductivity and combines optimum thermal dissipation with outstanding material compatibility and aging stability.
“The heat development in batteries and fuel cells is enormous. The demands on the coolant are correspondingly high. Our FCF 20 is not only designed for thermal release, but also offers the LIQUI MOLY’s typical long-term protection for all components,” Kaiser said.
Optimum thermal release is essential with fuel cells, as the heat generated can be higher than with classic, comparatively powerful combustion engines. This guarantees the maximum service life of the components. The product is also suitable for the Toyota Mirai, which is considered a pioneer in fuel cell technology.
Further development is aimed at purely battery-powered vehicles, which are much more common on our roads.
“It is a misconception that electric vehicles do not need oil. In fact, they need very high-quality lubricant for the transmission,” Kaiser said.
The new Top Tec Gear EV 510 gear oil meets the strict manufacturer requirements of Tesla. “We put our entire experience from research into the development of special e-products. These include, for example, low-conductivity coolants for e-vehicle batteries. These will also go on sale in the foreseeable future.”
