Bus going down a slope

Start Saving Brakes

The ERS saves energy by slowing the vehicle down while converting motion energy into stored pressure. In other words, for most situations of slowing down and stopping, the ERS becomes the primary braking system. The standard brakes are needed if slowing down above 40 mph, or to hold the vehicle stationary once stopped, but for most urban driving, the ERS does most of the deceleration.

The standard brakes won’t usually get hot. After all, the ERS’s function is to convert energy into something that can be reused, not into heat which dissipates and is lost. This means that the brakes are less likely to fade through overheating.

Finally, reduced brake wear is good for the environment too – read more here.

Retarder

The ERS can operate as a brake retarder on long downgrades. Once the accumulator has reached its capacity, it won’t accept any more energy; but the braking behavior of the ERS will remain in effect, controlling the vehicle’s speed while sparing the standard brakes.
