Dynamic allocation of power modules for charging electric vehicles is described herein. The charging system includes multiple dispensers that each include one or more power modules that can supply power to any one of the dispensers at a time. A dispenser includes a first power bus that is switchably connected to one or more local power modules and switchably connected to one or more power modules located remotely in another dispenser. The one or more local power modules are switchably connected to a second power bus in the other dispenser. The dispenser includes a control unit that is to cause the local power modules and the remote power modules to switchably connect and disconnect from the first power bus to dynamically allocate the power modules between the dispenser and the other dispenser.

Dynamic allocation of power modules for charging electric vehicles

Dynamic allocation of power modules for charging electric vehicles is described herein. A power cabinet includes multiple power modules that each are capable of supplying an amount of power to a dispenser. Multiple dispensers are coupled with the same power cabinet. A first power bus couples a first dispenser and switchably connects the power modules to the first dispenser; and a second power bus couples a second dispenser and switchably connects the power modules to the second dispenser. The power cabinet includes a control unit that is configured to cause the power modules to switchably connect and disconnect from the first power bus and the second power bus to dynamically allocate the power modules between the first dispenser and the second dispenser.

Networked electric vehicle charging stations for charging electric vehicles are coupled with an electric vehicle charging station network server that performs authorization for charging session requests while the communication connection between the charging stations and the server are operating correctly. When the communication connection is not operating correctly, the networked electric vehicle charging stations enter into a local authorization mode to perform a local authorization process for incoming charging session requests.

Authorization in a networked electric vehicle charging system

Automatically identifying an electric vehicle supply equipment (EVSE) is described. A receiver device receives wireless signals from EVSEs, where each wireless signal includes an identifier that is associated with the one of the EVSEs from which that wireless signal is received. The receiver device records signal strength values of the wireless signals and determines, based on the recorded signal strength values, which of the EVSEs is closest to the receiver device. The receiver device initiates a request for an action at the EVSE determined to be closest to the receiver device.

Automatically identifying an intended electric vehicle supply equipment

An electric vehicle charging station that is installed in a residence is coupled with a main circuit breaker in an electrical service panel. The charging station includes a charging point connection that couples an electric vehicle to a set of service drop power lines that provide electricity from a power grid to the residence; a current control device coupled to control the amount of electric current that can be drawn from the set of service drop power lines by an the electric vehicle through the charging point connection; a receiver to receive energy readings from one or more current monitors that indicate an amount of current is being drawn from the set of service drop power lines; and a set of control modules to cause the current control device to control the amount of current that can be drawn by the electric vehicle through the charging point connection based on the received energy readings to avoid tripping the main circuit breaker.

Method and apparatus for management of current load to an electric vehicle charging station in a residence

A plurality of charging equipment share a current capacity. A message is received that indicates a request for allocation of electric current through a first charging equipment of the plurality of charging equipment. Responsive to determining that granting the request would exceed the current capacity, the electric current is dynamically allocated among the plurality of charging equipment such that the first charging equipment is allocated electric current without exceeding the current capacity shared by the plurality of charging equipment.

Managing electric current allocation between charging equipment for charging electric vehicles

An external electric vehicle battery thermal management system is described. An electric vehicle thermal system provides external coolant to an internal battery thermal system of an electric vehicle. The internal battery thermal system includes a liquid-to-liquid heat exchanger to cool or warm the set of batteries of the electric vehicle. The external coolant is pumped through a first side of the heat exchanger and serves as the source to cool or heat internal coolant pumped through a second side of the heat exchanger. The external coolant and the internal coolant do not mix.

Electric vehicle charging system

An electric vehicle charging station network server that manages a plurality of charging stations receives subscriber notification message preferences for a subscriber (e.g., electric vehicle operator) that indicate one or more events of interest for which the subscriber wishes to receive notification messages. A set of one or more contact points associated with the subscriber is also received. The server receives data associated with the subscriber that indicates that a charging session at one of the charging stations has been established for an electric vehicle associated with the subscriber. The server detects an event of interest for the subscriber and transmits a notification message for that event to at least one of the set of contact points associated with the subscriber.

Transmitting notification messages for an electric vehicle charging network

A first dispenser receives a request to initiate charging service for charging an electric vehicle. The first dispenser determines an amount of power that is available for the charging service for charging the electric vehicle including determining an availability status of multiple power modules that are located in the first dispenser and a second dispenser. The first dispenser determines whether the available amount of power is enough to meet a requested or determined amount of power draw of the electric vehicle. If the available amount of power is not enough to meet the requested or determined amount of power draw of the electric vehicle, and if there is at least one of the power modules that is available, the first dispenser requests allocation of the available power module and charging service commences.
