According to one aspect, a lidar system is a lidar system which includes one set of mechanical, e.g., optical, components, and two or more sets of electrical and/or software components. The beams which are provided by the optical components are effectively alternated between a first and second sets of electrical and/or software components. The redundancy provided by the first and second sets of electrical and/or software components allows the lidar system to remain operational in the event that one set of electrical and/or software components becomes non-operational.

An electric vehicle charging system includes a power distributing system configured to receive power from a power control system and selectively direct the power to one of a plurality of power dispensers coupled to the power distribution system.

A server includes a communication device and a processor. The communication device obtains a power rate unit price dependent on a region where external charging is performed and a time slot when external charging is performed. The processor calculates a first power rate indicating a power rate when the external charging is performed with a first power feeding facility provided at a departure place before departure of a vehicle, calculates a second power rate indicating a power rate when the external charging is performed with a second power feeding facility provided in the vicinity of a traveling route after departure of the vehicle, and when the second power rate is lower than the first power rate, reduces an amount of power feeding during the external charging with the first power feeding facility, as compared with when the second power rate is equal to or higher than the first power rate.

An apparatus comprises a power electronic energy conversion system comprising a first energy storage device configured to store DC energy and a first voltage converter configured to convert a second voltage from a remote power supply into a first charging voltage configured to charge the first energy storage device. The apparatus also includes a first controller configured to control the first voltage converter to convert the second voltage into the first charging voltage and to provide the first charging voltage to the first energy storage device during a charging mode of operation and communicate with a second controller located remotely from the power electronic energy conversion system to cause a second charging voltage to be provided to the first energy storage device during the charging mode of operation to rapidly charge the first energy storage device.

An electric vehicle charging station charging electric vehicles dynamically responds to power limit messages. The charging station includes a charging port that is configured to electrically connect to an electric vehicle to provide power to charge that electric vehicle. The charging station also includes a power control unit coupled with the charging port, the power control unit configured to control an amount of power provided through the charging port. The charging station also includes a set of one or more charging station control modules that are configured to, in response to receipt of a message that indicates a request to limit an amount of power to an identified percentage and based on a history of power provided through the charging port over a period of time, cause the power control unit to limit the power provided through the charging port to the identified percentage.

The invention relates to a device and a method for automatically charging an electrical energy storage means in a vehicle. For this purpose, firstly, the position of a charging socket on a vehicle is determined, based on vehicle-specific data. Subsequently, a charging robot travels on the ground near to the charging socket. Then, the charging robot establishes a galvanic connection between the charging station and charging socket. For this purpose, the charging robot introduces a contact head connected to the charging station into the charging socket of the vehicle. After termination of the charging process, the contact head is removed from the charging socket, thereby releasing the vehicle.

A matrix-type flexible charging pile and a charging method capable of dynamically allocating power are disclosed in the present invention, and the method comprises the steps of: S1, connecting each charging terminal to a corresponding electric vehicle; S2, receiving a charging power demand of the electric vehicle and comparing the charging power demand; S3, calculating the number of charging modules required to be additionally allocated to the present DC-bus and delivering it to a matrix controller; and S4, allocating the required number of charging modules in a dynamic power region to the corresponding DC bus and switching the module communication line to a corresponding communication bus synchronously. The implementation of the charging method capable of dynamically allocating power can satisfy the electric vehicle charging demands for different energy storage capacities and different charging rates, as well as improve the conversion efficiency and the utilization rate of the charging device further.
