Embodiment Construction

[0027] 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.

[0028] 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.

[0029] 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 electrical energy metering and fee charging system of an electric automobile with a charging and electricity-switching mixed mode. The head and tail of the electric automobile are provided with charge interfaces; a charge pile or commercial power charging mode is adopted for the charge interfaces to charge, and a vehicle-mounted metering device is used for recording charged electricity; under a charge pile charging mode, a charge pile charging is started by virtue of a cryptographic key, and the fee charging mode is a charge fee charging mode or a post-paid mode; under a commercial power charging mode, a socket is used for providing electricity, and the electricity charge is not needed to be paid during following running; the electric automobile is provided with multiple slots; the battery service fee is debited from a CPU (Central Processing unit) card inserted into the vehicle-mounted metering device according to the electricity proportion. The system can be used for solving the accurate billing problem under different charge and electricity switching modes, guiding a user to use an own berth slow-charge mode, and reducing the impact to an electric network; different entities can be conveniently introduced to participate in investment and construction of charging equipment, charge piles and electricity switching stations, and the development of a vehicle battery and charging equipment technology is promoted.

Description

[0001] technical field [0002] 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 [0003] 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). [0004] 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. [0005] 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 equip...
