The invention relates to the field of movable charging vehicles, and specifically provides a start locking system for a movable charging vehicle. The invention aims to overcome the defect that the movable charging vehicle can still be started and moved during the being charging and charging of an onboard energy storage system. The start locking system of the invention comprises: a start loop, the movable charging vehicle being able to start when the start loop is switched on; and a first detection element for identifying whether an onboard energy storage system is able to enter an operating state, with the first detection element accessing the start loop, wherein the first detection element disconnects the start loop when the onboard energy storage system is able to enter an operating state. With the above structure, the start locking system of the invention can lock the start of the movable charging vehicle during the being charging and charging of the onboard energy storage system, thereby improving the safety performance of the movable charging vehicle.

Embodiments disclose a multi-frequency transceiver and a base station. The multi-frequency transceiver is connected to an antenna, and includes: at least one transmit multiplexer, where each transmit multiplexer includes multiple transmit paths, and each transmit path is used to transmit one frequency band by using the antenna; and at least one receive multiplexer, where each receive multiplexer includes multiple receive paths, and each receive path is used to receive one frequency band by using the antenna.

Multi-frequency transceiver and base station

A modularised charging vehicle, aiming at solving the problem of repeated development caused by the fact that an existing charging vehicle needs to configure separate charging piles for various specifications of electric automobiles. A charging vehicle comprises a main controller and at least two charging and discharging modules, wherein the charging and discharging modules comprise a charging input end, a battery pack, a DC/DC converter and a charging output end. The battery pack is connected to the charging input end and the DC/DC converter. The DC/DC converter is connected to the charging output end. The charging and discharging modules are connected in parallel to each other, and are combined into one path for inputting and are combined into one path for outputting. The controller can control the charging and discharging modules to store and release electric energy, so as to achieve an input or output function of different power.

An electrical tilt apparatus is provided, to ensure that when a quantity of serial ports on a remote control unit (RCU) is limited, independent electrical tilt on RF signals is provided. The apparatus includes: an RCU, and at least one combiner unit and multiple phase shifters connected to the RCU. Each of the at least one combiner units is connected to a different serial port on the RCU and connected to at least two RF modules; receives, at each time, an electrical tilt signal from one of the RF modules, and sends the electrical tilt signal to the RCU. The RCU receives the electrical tilt signal from each combiner unit, and drives, according to the electrical tilt signal, a first phase shifter that corresponds to a first RF module to move.
