Translations:Rheostatic & Regenerative Brake/3/en

The way rheostatic and regenerative systems differ, is that rheostatic braking passes the generated electricity through powerful resistors (rheostats), which slows down the vehicle at the cost of creating heat, dissipated into the atmosphere by powerful fans. Regenerative braking, instead of turning electricity into heat, slows down the vehicle by feeding the electricity back to the grid , or recharges onboard batteries .
