The cooperative regenerative braking system ensures that as much braking energy as possible is recuperated and stored as electrical energy. To do this, the generator is used to slow the vehicle down. As soon as the braking requirements exceed the braking capacity of the generator, the classic wheel brakes are applied. B4169x is a standard solution and can vary in capacitance value and voltage. For example, for this type, EPCOS offers a 500 µF capacitor at 63V with 125°C temperature rating to meet the automotive standards.
