Embodiment Construction

[0026] The present invention will be further described below in conjunction with embodiment. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0027] Charging interface settings and working principle : A standard charging socket is set at the front and rear of the car (the standard can be dominated by the power industry), which is convenient for parking and charging, and increases the convenience of using the wire harness.

[0028] The charging port can provide a special charging pile for charging, and the charging start needs a key to start (started by the on-board metering device). Payment, the metering device records the charged electricity, and this part of the electricity will not be charged for subsequent driving) or post-payment mode (real-time payment is made by the CPU card inserted into the on-board metering device during vehicle driving)....

Abstract

The invention discloses an electric energy metering and charging system for an electric vehicle with a hybrid mode of plugging in and swapping electricity. Charging interfaces are provided at the front and rear of the electric vehicle, and the charging interface adopts charging piles or commercial power charging modes for charging, and is metered by the vehicle. The device records the charged power; in the charging pile charging mode, the charging pile is activated by the key, and the charging mode is charging charging mode or post-payment mode; in the mains charging mode, the power is provided by the socket, and this part of the power will no longer pay. There are multiple slots on the electric vehicle; the battery usage fee is deducted from the CPU card inserted into the on-board metering device according to the proportion of electricity. The invention solves the problem of accurate billing under different charging and battery replacement modes, can guide users to use the slow charging mode of their own parking spaces, and reduces the impact on the power grid; it is convenient to introduce different entities to participate in the investment and construction of charging equipment, charging piles and battery replacement stations , to promote the development of vehicle battery and charging equipment technology.

Description

technical field [0001] The invention relates to an electric energy metering and charging system for a plug-in-electricity-swapping mixed-mode electric vehicle, belonging to the technical field of electric power metering. Background technique [0002] The existing electric vehicle (pure electric) technology mainly adopts the pure plug-in mode and the plug-in hybrid mode (battery-swapping technology cars basically have a plug-in mode). [0003] The simple plug-in mode has the problems of long charging time and large fluctuations in charging load (fast charging mode), which has a large impact on the power grid, which brings obstacles to the popularization and application of electric vehicles. [0004] The battery-swapping and plug-in hybrid mode has higher operational convenience. The battery-swapping station can be arranged in the same way as ordinary gas stations, and the battery-swapping time can be controlled; parking spaces can be equipped with slow-charging equipment, and...
