Abstract

The embodiment provides a general charger for a stabilized power supply stacked general electric automobile charging station. The generation charger comprises an input circuit, a transformation circuit, an output circuit, a voltage superposition module, a detection module, a control circuit and a communication module, wherein the transformation circuit is used for adjusting a voltage and a current inputted by the input circuit according to an instruction of the control circuit and then sending the voltage and the current after adjustment to the output circuit, the voltage superposition module is used for carrying out series superposition of the voltages inputted by the output circuit and an external DC stabilized power supply input module, the detection module is connected with the voltage superposition module and is used for sampling the voltage and / or the current, and the control circuit is used for controlling the output switch and the transformation circuit according to a detection result of the detection module and the information received by the communication module. The general charger is advantaged in that the general charger has the self-contained power supply and can be in series connection with the external stabilized power supply, voltage output is carried out after voltage superposition, so the output voltage can be flexibly changed through the charger, and adaptation to different electric automobiles is realized.

Description

technical field [0001] The invention belongs to the field of chargers, in particular to a universal charger for electric vehicles that can be stacked with a stabilized power supply. Background technique [0002] New energy electric vehicles have voltage and capacity requirements for the battery pack as a power source. The battery pack is often composed of thousands of single cells connected in series and parallel. The system voltage varies from tens of volts to hundreds of volts, and the capacity of the battery pack varies from tens of KWH to hundreds of KWH. [0003] The current charging station (pile) is an independent special device that provides charging voltage according to the battery pack voltage of the electric vehicle, and provides charging current according to the battery pack capacity of the electric vehicle. The charging station or charging pile is basically a special equipment for a specific electric vehicle, which has poor adaptability and is difficult to meet...
