The present invention relates to a method and arrangements for determining charging related to a data bit transfer session from a traffic source (209) to a client (213), said bit transfer session involving bit transfer over a wireless communications link (214f) under the control of a radio resource managing unit (204). According to the method of the present invention the radio resource managing unit (204) sends information regarding the bandwidth on the wireless link that the bit transfer session currently is allowed to use to a charging logic (212). This bandwidth information from the radio resource managing unit (204) is used by the charging logic (212) to determine the charging related to the bit transfer session. Thereby a fair charging of the session may be achieved, which is adapted to the quality of service actually obtained by the end-user for the session.

The invention discloses a control method for charging and a device thereof, a storage medium and charging equipment. The method is specifically as follows: positioning to-be-charged equipment and charging equipment to be adjacent to each other, namely, a first relative location; and performing location alignment by adopting the mark recognition technology when the to-be-charged equipment and the charging equipment are close to each other, thereby eliminating the deviation. Collecting equipment is used for connecting and recognizing the mark, a control device and an execution device are combined so as to perform more precise matching on the charging equipment and the to-be-charged equipment. For some to-be-charged equipment with low flexibility, the adjusting and recognition of the to-be-charged equipment are unnecessary, the matching speed is fast and the flexibility is good; the charging device and the to-be-charged device are adjusted in real time according to the information continuously collected by the collecting device, and the positioning precision is high.

The invention relates to the technical field of charging piles, in particular to a rail-mounted new energy charging pile. According to the rail-mounted new energy charging pile, a device box can movealong a rail to the position above an electric automobile, the electric automobile is conveniently charged, the inconvenience caused by the fact that the position of the device box cannot be adjustedin time is greatly avoided, and the use rate of the charging pile is increased. The charging pile has a buffering function, and the situation that a sliding seat collides with other sliding seats whenmoving on the rail and thus electric components in the device box are damaged is prevented. When not used, the device box can be stored in a containing box, the situation that the electric componentsin the device box are weathered and corroded or a short circuit accident happens due to the fact that the electric components are wetted by rainwater and thus potential safety hazards are generated is prevented, and therefore the charging pile charges the electric automobile more safely, economically and flexibly. Sliding ways are arranged on the rail, and the two sliding ways are symmetrically arranged at the front end and the rear end of the rail. Vertical seat boards are fixedly connected with the left end and the right end of the sliding seat, and sliding strips are fixedly connected withthe front end and the rear end of the sliding seat.

The invention discloses a front-end integrated multi-port power converter of a switched reluctance motor, which is suitable for the technical field of switched reluctance motor control. The converter is composed of a front-end integrated power supply circuit and multiple bridge arm units. The front-end integrated circuit consists of a battery pack, a photovoltaic panel power supply, 2 insulated gate bipolar transistors, an energy storage capacitor and 3 freewheeling diodes. Each bridge arm is composed of 2 insulated gate bipolar transistors and 2 freewheeling diodes, and the number of bridge arms is the same as the number of phases of the switched reluctance motor. The present invention does not require complex control strategies and has a simple structure; compared with traditional power converters, it realizes the combined power supply of photovoltaic panel power supply and battery pack, increases the voltage of the DC bus and flexibly charges the battery pack, and improves the utilization rate of electric energy; Multi-level excitation and demagnetization are realized when single-source power supply, which speeds up the process of excitation and demagnetization, and improves the overall efficiency of the system.
