Embodiment 1

[0022] Embodiment 1: The card reader is installed in the electric vehicle. figure 1 It is a functional block diagram of the system, which is composed of a main control unit, a display unit, a power measurement unit, an electrical connector, a self-test status indicator, a trigger switch and a DC power supply. The electrical connector adopts figure 2 The data line power line integration method shown, image 3 It is the structure diagram of this charging pile.

[0023] The charging workflow is as follows Figure 4 . Specifically: the driver finds a charging pile with a status of "equipment is free and available", inserts the card in the car, and gets off the car to plug in the electrical connector. At this time, the data connection between the charging pile and the on-board power control system has been connected, but the power cord is disconnected, the charging pile itself is powered by the mains, and the on-board power control system is supplied by the remaining power of ...

Embodiment 2

[0024] Embodiment 2: The card reader is set on the charging pile. Figure 5 A schematic diagram of the system. The specific charging process is the same as that of Embodiment 1, and will not be described in detail.

[0025] The charging pile charging system involved in the present invention is suitable for construction in cities, certain districts of cities, counties, towns, and communities, and for participating in the construction of new rural areas. The charging pile charging system involved in the present invention is also suitable for intercity and townships , Charging network construction for various road traffic between villages and towns.

[0026] The charging pile charging system involved in the present invention can provide charging services for pure electric vehicles, gasoline-electric hybrid vehicles, and gas-electric hybrid vehicles.

[0027] The battery pack involved in the present invention may be a lithium-ion battery pack, a nickel-metal hydride battery pack...

Abstract

The invention relates to a charging method of charging pile for supplying charging service to an electromobile, which has the following steps of: 1) stopping an electromobile at the front of a workable charging pile, connecting the charging pile with mains supply, socketing an electric connector on a vehicle power control system arranged on the electromobile, and inserting a charging card into a card reader; 2) reading user information in the charging card by the charging pile, and detecting the availability of the charging card corresponding to the battery packs and the electromobile; 3) detecting the electric quantity remaining balance of the charging card, under the condition of continuous charging, collecting and detecting the imbalance degree between the battery packs and single batteries by a main control unit; if the imbalance degree exceeds a prior set value, giving the alarm display and prompting the balanced maintenance for battery packs timely by the main control unit; 5) in the charging process, displaying the charging accumulative total power consumption and the charging state alarm in a real time; and 6) and when the charge is ended, displaying the remaining balance of the charging card on a display unit, performing balance judgment between the battery packs and the single batteries, and displaying the imbalance degree state information. The charging system has the functions of real time collection of battery pack state information and real time balance treatment when the electromobile is charged, and has the advantages of reasonable human-computer interface, accurate electric quantity measurement, convenience of connection and good additional value-added function.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a charging method for a charging pile that provides charging services for electric vehicles. Background technique [0002] The development of electric vehicles is a huge systematic project, including the production of power battery packs, production of electric vehicles, construction of supporting charging networks, maintenance of complete vehicles and accessories, etc. Among them, the supporting charging network is an essential support system, similar to the gas stations of traditional fuel vehicles, and is a prerequisite for the promotion of electric vehicles. [0003] There are two ways to supplement the electric energy of electric vehicles: replacing the battery pack and charging the whole vehicle. Charging piles are the main equipment to provide convenient instant or parking space vehicle charging services, but the known charging piles are often only a kind o...
