摘要： A concrete mixer vehicle includes a mixer drum assembly, an energy storage device, an internal combustion engine, an auxiliary power unit, and an energy management controller. The internal combustion engine is configured to supply power to the mixer drum assembly. The auxiliary power unit is configured to supply power from the energy storage device to the mixer drum assembly. The energy management controller is configured to engage the APU and disengage the ICE based on a state of charge of the energy storage device.
