A charging coupler has a grip, an electrical connector and a cable holder. The grip has a front opening and a rear opening on two ends thereof The grip has a first half-tube and a second half-tube connected with each other along a longitudinal direction thereof. The first half-tube has a first latch portion and a groove extending along edges thereof to connect the second half-tube. The second half-tube has a second latch portion and a rib extending along edges thereof to connect the first half-tube. The rib is substantially matched with the groove, and a sealant is filled in a gap between the rib and the groove. The first latch portion is latched with the second latch portion to tighten connection of the first half-tube and the second half-tube. The electrical connector is arranged on the front opening, and the cable holder is arranged on the rear opening.

A battery system includes a rechargeable energy storage system and a battery controller. The rechargeable energy storage system has a rapid charging mode and a discharging mode. The battery controller is electrically coupled to the rechargeable energy storage system and is configured to store multiple charging tables that contain multiple charge current limit entries, where each charging table corresponds to a unique one of multiple initial state-of-charge values, determine a starting state-of-charge value of the rechargeable energy storage system in response to entering the rapid charging mode, select up to two charging tables in response to the starting state-of-charge value of the rechargeable energy storage system being adjacent to up to two of the initial state-of-charge values, and control a charging current provided to the rechargeable energy storage system based on the charge current limit entries in the up to two charging tables as selected.

A system for charging one or more batteries of a vehicle may include a charging box mounted to a vehicle to facilitate connection to a charge coupler from under the vehicle. The charge coupler may be configured to provide an electrical connection between an electrical power source and the charging box. A vehicle including the charging box may maneuver to a position above the charge coupler, after which electrical contacts of the charging box and the charge coupler may be brought into contact with one another. The charge coupler and/or the charging box may be configured to provide electrical communication between the electrical power source and the one or more batteries, so that the electrical power source may charge one or more of the batteries. Thereafter, the electrical contacts may be separated from one another, and the vehicle may maneuver away from the charge coupler.

Disclosed is an apparatus for sensing a temperature of an electric vehicle charger during charging of an electric vehicle. The apparatus is configured to sense the temperature of a charging pins using a temperature sensor provided in a charging plug, to transmit the same to the charger by serial communication using the existing signal line without adding a separate signal line, and to be supplied with power necessary for ICs and devices in the charging plug using the existing signal line during charging of the electric vehicle.
