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.

Abstract: A charge head is connected to a charge inlet of an electric vehicle to supply an electric charge to recharge the battery of the vehicle. The charge head is attached to a connecting device that moves the charge head to the charge inlet. Multiple light detectors are provided on the charge head to sense light emitted from the vehicle. The system then uses a difference in the amount of light received by different light detectors to determine a direction to move the charge head toward the charge inlet.

Abstract: A method for preventing an inrush current of an electric vehicle charger may include the steps of determining whether there is a need for an increase or decrease in a charging current level while currently supplied to an electric vehicle to be charged; decreasing the charging current level at a predetermined ratio when it is determined that there is the need for the increase or decrease in the charging current level; checking whether an inrush current occurs for a first time; activating or deactivating at least one charging module to increase or decrease the charging current level according to the request of the electric vehicle to be charged, when the inrush current does not occur for the first time; checking whether the inrush current occurs for a second time; and increasing the charging current level by the charging current level requested by the electric vehicle to be charged, when the inrush current does not occur for the second time.

Abstract: A request to move along a route is detected. The request is from a first electric vehicle. The route may include a start point and an end point. It may be determined that the first vehicle is an electric vehicle including a battery. In response to determining that the first vehicle is an electric vehicle, one or more battery parameters of the first vehicle may be retrieved.

A subset of the electric vehicle chargers may be selected based on the battery parameters of the first vehicle. A second route is generated based on the subset of the electric vehicle chargers. The second route is generated such that the first vehicle is capable of reaching the end point. The route of the first vehicle may be replaced with the second route.
