Embodiment Construction

[0035] The present invention will be described in further detail below through specific embodiments in conjunction with the accompanying drawings, but the implementation and protection of the present invention are not limited thereto.

[0036] Such as figure 1 As shown, the present embodiment is a semi-vehicle fast charging device for an electric bus, including a ground part and a vehicle part arranged on the electric bus. The ground part includes a step-down transformer and an AC filter circuit, and the vehicle part includes a motor controller, a DC filter Circuits and high-voltage batteries, the three-phase AC output from the three-phase AC power grid is isolated and stepped down by the step-down transformer, and then filtered through the AC filter circuit, and the motor controller performs AC-DC conversion on the filtered three-phase AC to DC, DC After being filtered by the DC filter circuit, the high-voltage battery is quickly charged.

Abstract

The invention discloses a semi vehicle-mounted rapid charging method and charging device of a power-driven bus. The power-driven bus comprises a motor controller and a high-voltage battery and is characterized in that three-phase alternating current output from a three-phase AC power grid is isolated and bucked and then is filtered, the motor controller is used for AC-DC conversion on the filtered three-phase alternating current to direct current, the high-voltage battery is rapidly charged after the direct current is filtered, a simple, convenient and flexible charging mode of a vehicle-mounted charger can be inherited, the volume cost limitation is also overcome, the charging current at the same power level of a non-vehicle-mounted charger is provided, the charging flexibility of the power-driven bus is improved, the adaptability and the activity space of the power-driven bus are expanded, the comprehensive performance is more excellent, and the industry development of the power-driven bus is promoted.

Description

Technical field: [0001] The invention relates to a half-vehicle fast charging method for an electric bus and a charging device thereof, belonging to the technical field of electric vehicle charging. Background technique: [0002] Contact chargers are mainly divided into two types: on-board chargers and off-board chargers. The on-board charger is a charger that is fixedly installed on the electric vehicle. The charging method is simple and flexible. The supporting charging station has less investment, but the charging speed is slow and the time is long. The reason is that the available space on the electric vehicle is small, and at the same time, in order to reduce the weight of the electric vehicle, when making the on-board charger, try to ensure that the on-board charger is small in size and light in weight. Due to volume and cost issues, high-power on-board chargers with hundreds of amperes of current cannot be used in electric buses. [0003] The off-board charger needs...
