The technical vehicle is composed of motorcar chassis, autobody, power set, voltage transforming and regulating system, voltage and current limiting system, DC rectification system, charging control system and rise and fall enable working platform system. If transit trolley with super capacitance takes long-distance transport, the technical vehicle can go with it and supplies electric energy to it. If transit trolley is broken down caused by shortage of electricity, the technical vehicle can charge it to resume normal operation. If charging station is in failure, the technical vehicle can be as temporary charging station. The rise and fall enable working platform system is in use for installing and maintaining charging stations. |
