Abstract: A heavy-duty electric vehicle having a pneumatic brake may include at least one electric motor configured to propel the vehicle, and a battery system configured to provide power to the at least one electric motor. The battery system may be configured to be recharged by regenerative braking of the vehicle. The vehicle may also include a braking system. The braking system may be configured to (a) apply substantially only regenerative braking to slow the vehicle during initial slowdown and (b) subsequently apply both regenerative braking and pneumatic braking after the initial slowdown.
