Abstract

An embodiment of the present application provides a universal charger for a general-purpose electric vehicle charging station with stacked regulated power supplies, including: an input circuit, a conversion circuit, an output circuit, a voltage superposition module, a detection module, a control circuit, and a communication module; According to the instructions of the control circuit, the voltage and current input by the input circuit are adjusted and then sent to the output circuit; the voltage superposition module is used for series superposition of the output circuit and the voltage input by the external DC stabilized power supply input module; the detection module and the voltage superposition The modules are connected and used for sampling the voltage and / or current; the control circuit is used for controlling the output switch and the conversion circuit according to the detection result of the detection module and the information received by the communication module. The invention provides a universal charger which includes its own power supply and can be connected in series with an external voltage-stabilizing power supply to superimpose the voltage and output it. Such a charger can flexibly change the output voltage to suit different electric vehicles.

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...
