Abstract

An electric vehicle charging-control system includes a charge-monitoring device coupled with a battery system of an electric vehicle, a processor coupled with the charge-monitoring device, and a communication interface coupled with the processor. The charge-monitoring device may detect the charging conditions of an electricity charge provided from a charging device to the battery system for charging the battery system, and the processor may determine whether the charging conditions exceed a tolerance criteria associated with at least one of the charge-monitoring device, the battery system, and the electric vehicle. The communication interface may communicate to the charge-monitoring device, a charge-receiving device, and/or the charging device at least one of a charging instruction and a charging indication provided by the processor based on a determination of whether the charging conditions exceed the tolerance criteria.
