A method of operating an electric vehicle charging system utilizing a plurality of charging units and charging points and a vehicle charging system are disclosed. The method includes determining a rate of charge to be delivered to each vehicle and then allocating a respective portion of the total charging capacity of the charging station to each vehicle.

Battery charging station

A method of thermally pre-conditioning a vehicle's battery pack prior to vehicle departure is provided. The system, after determining that the vehicle is off and/or the driver has left the car, monitors a variety of conditions corresponding to both the vehicle and the driver in order to determine the probability of the driver requiring near-term use of the car. Typical monitored conditions may include driver and vehicle location, driver proximity, time of day, day of week, driver's upcoming appointments, and a historical data base that tracks driver behavior. Once the probability that the car will be needed within a preset time period exceeds a preset level, the system determines whether the battery pack should be heated or cooled based on the current battery pack temperature, and then activates an appropriate thermal management system.

Method of operating a preemptive EV battery pack temperature control system

The invention relates to a battery assembly with high thermal conductivity. The battery assembly comprises a metal case having a hollow accommodation cavity formed therein, a plurality of battery cells installed parallel to one another within the metal case, and a common electrode for connection to the other electrode in each of the battery cells. Each of the battery cells has two electrodes, with one of the electrodes that corresponds to those of the rest of the battery cells being connected in a thermally conductive manner to the metal case. The invention takes advantage of high thermal conductivity of metallic material and dissipates heat by connecting the metal case to the battery electrodes. The invention further comprises fixation troughs formed on the metal case, thereby reducing the size of the assembly.

The method includes determining a rate of charge to be delivered to each vehicle and then allocating a respective portion of the total charging capacity of the charging station to each vehicle.

In a battery pack having multiple battery cells distributed, for example, between multiple interconnected battery modules, a run-time cooling system is provided to cool (and/or heat) the battery cells during routine charging and discharging of the cells (e.g., powering a load such as a motor within an electric or hybrid-electric vehicle), and an emergency cooling system to cool the battery cells in response to a signal indicating detection of one or more conditions indicating possible thermal runaway within the battery cells or battery modules. The run-time cooling system, which may include a fan, HVAC unit or other fluid pumping device, induces continuous coolant flow within the battery pack (e.g., flow of air or other gaseous or liquid coolant). The emergency cooling system, by contrast, includes a mechanical interface or is otherwise adapted to receive a receptacle containing pressurized coolant or other flash-cooling device.

Flash cooling system for increased battery safety

A power conversion system is disclosed. The system comprises a plurality of power conversion modules and a controller that turns on/off each power conversion module separately based on changing load conditions, and manages to keep each power conversion module running at its peak efficient state.
