Electric Cars Brake Reliably With LIQUI MOLY

Brake Fluid DOT 5.1 EV was developed for the systems of modern vehicles that are also installed in electric vehicles.

Many things are different for hybrid and all-electric vehicles than for cars with conventional combustion engines. This applies to the drive as well as to the parts that ensure that the acceleration generated is reduced again: the brakes. Vehicle chemistry specialist LIQUI MOLY has developed a brake fluid especially for electrically operated vehicles: DOT 5.1 EV – there are several reasons for this innovation.

Vehicles with a conventional combustion engine have a brake system – electric and hybrid cars too. All of them usually require the brake fluid to be changed every two years. “But that’s about it for the similarities, because the requirement profile of the electric vehicles is sometimes completely different,” David Kaiser knows. He heads the Research & Development department at LIQUI MOLY. That’s why the specialist for vehicle chemicals has developed the Brake Fluid DOT 5.1 EV. EV stands for Electric Vehicle.

There are a number of reasons why brake systems are more demanding for vehicles that are partly or even purely electrically powered. “One is corrosion protection,” says David Kaiser. “Because the electric motor also acts as a brake and uses it to generate energy for the battery, the mechanical brake system is used less frequently. This leads to spot corrosion.” Special additives counteract this effect.

“However, this does not mean that a brake system in an electric vehicle does only a little work,” says the Head of Development at LIQUI MOLY. “These vehicles are generally heavier than vehicles that are powered by an internal combustion engine and rapidly reach high speeds from which they also have to be braked abruptly in the event of danger. As a result, the brakes quickly become very hot. Brake fluids such as our new DOT 5.1 EV have to be effective even when the brake system is hot and therefore require a high dry and high wet boiling point.”

Property number three is the lowest possible electrical conductivity. This plays a role if an electrical system is installed near the brake system and is not sufficiently shielded. As with the wireless, inductive charging of an electric toothbrush or mobile phone, electrical voltages can then be induced in the brake system, which can decompose the brake fluid or promote corrosion.

The fourth property of interest is viscosity. “As with motor oil, the flow behavior is decisive for the performance of the fluid. The lower the viscosity, the faster the engine is fully oiled. A low-viscosity brake fluid transmits the braking pulses in the system more quickly, the electronic driver assistance systems such as ABS or ESC function better and respond even more sensitively,” David Kaiser points out.

The same applies to brake fluids as to motor oils: Only use what should be used. Approvals and specifications are the measure of all things.
