Abstract
An electrical drive system that modifies operation between that of a generator and a motor based on changes in operation of a tractor and machine scraper in order to charge the electrical drive system when the machine scraper is empty or being unloaded and to power the drive of the machine scraper when the machine scraper is cutting and loading a bowl of the machine scraper and during the transport of the load from the location of the cutting and loading.
Claims20
An electrical drive system, comprising:
- a battery pack;
- an electrical drive device in electrical communication with the battery pack;
- a power control system connected to the electrical drive device;
- a power conditioning circuit connected to the electrical drive device and the power control system;
- a powered axle connected to the electrical drive device;
- and
- wherein the power control system and the electrical drive device are configured to operate as a generator through passive rotation of the powered axle to create power that is stored in the battery pack;
- wherein the electrical drive device and the power control system are configured to operate as a motor by providing power stored in the battery pack to the powered axle;
- wherein the electrical drive device and the power control system are configured to operate in an empty phase, a cutting/loading phase, a transport phase, and a fill/dump phase.
