A work vehicle having a hydrostatic drive system (10, 12, 16, 18) provides for the recovery and reuse of the vehicle's kinetic energy by conducting pressurized hydraulic fluid out of the hydrostatic drive system into an accumulator (34) during vehicle dece...

The system has a driving unit (15) installed on an automobile drive shaft (10) to grasp at a clutch that drives a power generator (40). The generator converts a braking inertia kinetic energy into pressurized air to be stored in a power tank (50). The shaf...

Maximum charging power of a battery (63) is set by a battery-charging power setting unit (75), while maximum discharging power of the battery (63) is set by a battery-discharging power setting unit (76). Lower and upper limit of generator output power is s...
