HYBRID ENERGY SYSTEM FOR TRACTION VEHICLES

摘要

An energy transfer and storage system for traction vehicles which have at least one electric motor/generator (32) and at least one traction wheel (16) is provided, and has a primary energy source (60), a hybrid battery system (62), and a drive/brake control system (52) associated with said at least one traction wheel, which generates electrical power during a braking operation to deliver to the hybrid battery system. The primary energy source may be an internal combustion engine together with an electrical generator, or a fuel cell. The hybrid battery system includes a first high capacity battery (70) having a high electrical energy storage capacity and a high electrical current pass-through capacity; and a second electrical energy storage device (72) having a low energy storage capacity compared to the first high capacity battery, a high electrical current pass-through capacity, a steeply rising output voltage characteristic during charge conditions and a steeply falling output voltage characteristic during discharge conditions.
