The method is used to heat the power battery.

In a case where an external charging start time is set in an external charging timer when a charging plug is connected to a charging connector, a charging controller is configured to perform standby setting of external charging before the external charging start time and transits to a pause state. The charging controller is intermittently activated during a timer charging setting period from a pause period start time when transition is made to the pause state to the external charging start time, and when a battery temperature at the time of activation of the charging controller is equal to or lower than a predetermined temperature, execute a temperature increase mode in which a heater is operated to increase the temperature of a main battery.

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.

The present invention discloses a system for managing rechargeable batteries to provide power to electrical vehicles. The system comprises a plurality of charging stations each if the intelligent charger includes at least an intelligent battery charger for charging the rechargeable batteries. The intelligent battery chargers further comprises a battery diagnostic detector for detecting and storing data of designated battery health management parameters. The intelligent battery chargers further comprises a transmitter for transmitting the data of the designated battery health management parameters as wireless signals to a networked server in a battery management center.

An electrical energy storage device includes prismatic energy storage cells arranged adjacent to one another such that interfaces of adjacent storage cells run at a distance from one another such that the interfaces of the adjacent storage cells form an intermediate space. A respective first layer is arranged between the interfaces of adjacent storage cells, the first layer abutting one of the two interfaces of the adjacent storage cells under pressure. Either the respective first layer also abuts the second of the two interfaces of the adjacent storage cells under pressure, or a second layer is arranged between the interfaces of adjacent storage cells, the second layer abutting the second of the two interfaces of the adjacent storage cells under pressure. A heat-conducting device is arranged in or between the first layer and the second layer is conducted out of the intermediate space between the adjacent storage cells.

A battery with at least two battery cells, which are connected by at least one electric connection element to one another, and a superordinate control device. Each of the battery cells is provided with at least one galvanic element, a battery cell housing for accommodating the galvanic element, at least one sensor device for detecting a physical and/or chemical feature of the battery cell, and a communication device for communicating with the superordinate device. The superordinate device is adapted to control an energy flow in at least one of the battery cells and/or from at least one of the battery cells as a function of the physical and/or chemical features of the battery cell. The invention further also relates to a motor vehicle with such a battery.
