The invention discloses a charging method and charging system for a rail transit vehicle. The charging method includes the following steps: controlling an on-board unit to establish a microwave communication connection with a trackside unit; receiving query information sent by a station control unit through the microwave communication connection; Query information to obtain the first state information of the energy storage device; send the first state information to the station control unit through the microwave communication connection, so that the station control unit controls the power supply equipment to charge the energy storage device according to the first state information. Therefore, the charging method of the embodiment of the present invention can not only make the charging of rail transit vehicles convenient and reliable, but also facilitate operation, and optimize the charging process of rail transit vehicles.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a charging method for rail transit vehicles, a vehicle-mounted central control unit, a station control unit and a charging system for rail transit vehicles. Background technique [0002] Rail transit vehicles usually use flexible catenary to take power, and use pantograph or shoe-rail contact charging. This way of taking power is arranged with a power grid along the way, and the way of taking power and investment costs are generally high. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. [0004] For this reason, the first object of the present invention is to propose a charging method for rail transit vehicles, which can not only make the charging of rail transit vehicles convenient and reliable, but also facilitate operation and optimize the charging process o...
