Abstract

The invention provides a control device and a method thereof for a locomotive charger. In order to solve the problem that the existing locomotive charger has no temperature compensation function, and aiming at the charging control discontinuity of the charger, the invention is provided. The control device comprises a judgment unit, a voltage collection unit, a current collection unit, a floating charge control unit, a rapid charge control unit, a temperature collection unit, a voltage compensation unit and an execution unit, wherein the judgment unit is respectively connected with the voltage collection unit, the current collection unit, the floating charge control unit, the rapid charge control unit, the temperature collection unit, the voltage compensation unit and the execution unit. The invention has the advantages that the charge process can be controlled according to the temperature and the real-time voltage and current of an accumulator, and the charging is safer and more stable.

Description

technical field [0001] The invention relates to the field of electric locomotive charging, in particular to a control device and method for a locomotive charger. Background technique [0002] The charger on the electric locomotive mainly supplies power to the control system 110v and charges the battery, which is taken from the intermediate current of the auxiliary converter, and supplies power to the control device and the battery through charging. [0003] Chinese Patent Publication No. CN1725597A, an intelligent fast battery charger discloses a device for realizing battery charging control by using multi-level reference voltage control switches, but this scheme uses switch components to control, so that the control is discontinuous, so the battery monitoring response hysteresis, and the circuit structure is not suitable for high-voltage, high-frequency electric locomotive battery charging applications. [0004] Chinese Patent Publication No. CN1889323A, a temperature-sens...
