LIQUI MOLY has developed a coolant for fuel cells as well as a special transmission fluid solely for electric vehicles. Both are available now. 

David Kaiser, head of Research and Development at LIQUI MOLY, commented, “This is just the beginning of what we have in the pipeline. We stand by our promise – we offer the right products for all vehicles all over the world.”

In Europe, the U.S. and large parts of Asia, e-mobility is growing exponentially. Although the number of conventionally powered vehicles will continue to far exceed that of alternative drives in the coming decades, LIQUI MOLY says it is preparing for the mobility turnaround. 

“There will generally be a mix of different drive concepts,” said Kaiser. “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.”

Quality is the keyword at LIQUI MOLY. 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 company says. 

“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,” says Kaiser proudly. Optimum thermal release is absolutely 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 also is 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 German roads, says Kaiser. “It is a misconception that electric vehicles do not need oil. In fact, they need very high-quality lubricant for the transmission,” said Kaiser. 

Here, too, LIQUI MOLY offers the right fluid that is geared toward the high torque of powerful electric motors. The new Top Tec Gear EV 510 gear oil meets the strict manufacturer requirements of Tesla. The designation EV (Electric Vehicle) shows that this LIQUI MOLY product was developed exclusively for electric vehicles. But that’s not all. “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,” he added. 

In general, most LIQUI MOLY products are suitable for all drive types, whether combustion engine, electric, hybrid or fuel cell, according to the company. The manufacturer approvals are decisive. “Wherever special products are used, we will provide solutions. This is independent of the drive,” said Kaiser. 

With the new products, the full-range supplier is expanding its offering of some 4,000 items and rounding off its range to cater more for alternative drives.
