Abstract

The invention provides a battery control circuit for a double-electrical-energy locomotive, comprising a dc switch, a charger, batteries and isolated conversion units. When an overhead contact system supplies power for traction, the batteries are discharged through the charger and the isolated conversion units; when the batteries supply power for traction, the locomotive is pulled by electrical energy of the batteries through the isolated conversion unit and the dc switch; and when the locomotive is in a regenerative breaking condition, the batteries are charged by feedback braking energy of a traction motor through the charger and the isolated conversion units. The battery control unit provided in the invention can realize battery charge and discharge of the double-electrical-energy locomotive and can utilize breaking energy generated by breakings of the traction motor. The dc switch is not required to be disconnected when the batteries store braking energy, thereby avoiding frequent actions of the dc switch with the applications of electrical breakings, ensuring reliability of the dc switch, and prolonging service life of the dc switch. In addition, the battery control circuit for the double-electrical-energy locomotive of the invention can realize circuit extension and circuit isolation conveniently.

Description

technical field [0001] The invention relates to the field of locomotives, in particular to a storage battery control circuit for dual electric energy locomotives. Background technique [0002] The dual-electric locomotive can work under the two energy systems of the AC catenary and the traction battery. The control circuit of the dual-electric locomotive is mainly focused on the vehicle circuit system, and less attention is paid to the charging and discharging circuit of the battery of the dual-electric locomotive. [0003] At present, the charging and discharging circuit of the on-board battery is mainly researched on the regenerative braking charging of electric vehicles. However, the battery capacity of electric vehicles is small, and its control circuit is not suitable for the high power requirements of the battery in the operation of railway dual-electric locomotives. However, in the dual-electricity track engineering vehicle that uses the battery-catenary as the energy...
