Charging-discharging converter of electric vehicle battery pack

Abstract

The invention discloses a charging-discharging converter of an electric vehicle battery pack, and belongs to the technical field of electric energy. The converter is mainly composed of a power grid, afull-bridge converter, a bidirectional DC / DC, a storage battery, a DSP control unit and a panel display, and is characterized in that the power grid is connected with the full-bridge converter, the full-bridge converter is connected with the bidirectional DC / DC, and the bidirectional DC / DC is connected with the storage battery; the power grid, the full-bridge converter, the bidirectional DC / DC and the storage battery are all connected with the DSP control unit, and the display panel is connected with the DSP control unit. According to the charging-discharging converter of the electric vehiclebattery pack, when the electric vehicle battery pack needs to be charged, the converter is connected with a standard mains supply alternating current socket through a cable to charge the electric vehicle battery pack, and the plug and charge is achieved; when a vehicle runs outside or a family is powered off, the electric vehicle battery pack is used as a standby power supply, and the standard alternating-current electric energy is generated through the converter.

Description

Technical field [0001] The invention relates to a charge and discharge converter for an electric vehicle battery pack, belonging to the technical field of electric energy. Background technique [0002] The increase in the total number of vehicles has made exhaust gas one of the most important sources of air pollution in modern cities, leading to the rapid consumption of a large amount of non-renewable energy. In the environment of vigorously developing energy conservation and emission reduction and promoting the development of low-carbon economy, energy-saving and environmentally-friendly new energy vehicles represented by electric vehicles have received attention and promotion. At the same time, the related service areas for electric vehicles also need to develop rapidly. In order to meet the energy demand of electric vehicles in the market, it is necessary to build charging piles on a large scale, but the application of charging piles has not been fully popularized, and the con...
