Self-contained motorization system

摘要

602641 Disclosed is a self-contained motorization system including at least one electric motor (9), a controller adapted to drive the operation of the electric motor (9) and a set of accumulators of power type (5) adapted to feed the motor (9) by providing the instantaneous current consumed by the motor (9). A central control unit (7) commands a direct current converter and a base (3) removably receives a set of accumulators of energy type (4). The system also includes a direct current converter adapted to connect the set of accumulators of energy type (4) to the set of accumulators of power type (5) to control the charge of the set of accumulators of power type (5) by the set of accumulators of energy type (4) by providing a charge current to the set of accumulators of power type (5) that compensates on average the energy supplied to the motor. The set of accumulators of power type (5) are capable of supplying the maximum current sought by the motor (9).
