Abstract: Described herein are methods and systems for remote charging of work vehicles using recharge vehicles. A recharge vehicle is equipped with power storage that has a sufficient capacity for propelling the recharge vehicle between a charging station (used for charging the recharge vehicle) and a work location (of the work vehicle) and also for charging the work vehicle at the work location. In some examples, the charging of the work vehicle and even the connection between the vehicles are formed while the work vehicle continues to operate. This approach helps to maximize the operating time of the work vehicle. Furthermore, this approach relaxes the charge rate requirement for charging the recharge vehicle and also for charging the work vehicle as well as the location of the charging station (for charging the recharge vehicle). In some examples, work vehicles and/or recharge vehicles are autonomous vehicles and use vehicle-to-vehicle coordination features.
