Description

Technical Field

[0001] The present invention relates to the field of charge and discharge control of new energy vehicles, and in particular to a method and system for continuous charge and discharge control of new energy vehicles. Background Art

[0002] With the development and increasing number of electric vehicles, as well as the large-scale development of renewable energy, V2G (vehicle-to-grid) technology is a key technology for realizing the control of charging and discharging of new energy vehicles. It can realize the interaction of electric energy between electric vehicles and the grid after the electric vehicles are connected to the grid, make full use of the energy storage function of the on-board power battery, play the role of peak shaving and valley filling, promote the consumption of renewable energy and improve the stability of grid operation. The V2G technology used in the control of charging and discharging of new energy vehicles requires users to actively participate in the grid regulation process. The vehicle end charges from the grid during the off-peak period and discharges to the grid during the peak period, realizing the two-way flow of energy between electric vehicles and the grid, which can effectively reduce the investment in home or building energy storage infrastructure, meet the development requirements of smart grids, and better promote the consumption of renewable energy.

[0003] At present, V2G technology is quite mature in the control of charging and discharging of new energy vehicles. However, at this stage, it can only complete a single manually set charging or discharging action, that is, the user actively selects the charging and discharging mode (charging or discharging) of this operation. Once started, the charging and discharging mode cannot be switched during the execution process. If switching is required, it is necessary to stop the current charging and discharging process and restart it. The inconvenience of switching the charging and discharging mode makes the user experience poor, and they cannot actively participate in the grid regulation process, relieve the grid pressure, and help improve the stability of grid operation.

[0004] This is the shortcoming of the prior art. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a continuous charging and discharging control method and system for new energy vehicles, which are used to avoid users from switching charging and discharging modes, improve users' charging and discharging experience, and further promote users to actively participate in the grid regulation process, so as to alleviate grid pressure and improve the stability of grid operation.

[0019] Then, it is retrieved in real time whether the charging and discharging period of the current time has changed. If it has changed, the charging and discharging mode and charging and discharging power control value of the charging and discharging period after the change are extracted, and the vehicle is charged and discharged in the charging and discharging period after the change based on the extracted charging and discharging mode and charging and discharging power control value.

If they are equal, directly use the charging and discharging power control value required by the current vehicle as the charging and discharging power control value of the target vehicle corresponding to the current target charging and discharging period. If they are not equal, adjust the charging and discharging power control value of the current target charging and discharging period, and use the adjusted charging and discharging power control value of the vehicle as the charging and discharging power control value of the vehicle in the current target charging and discharging period;

If they are equal, directly use the charging and discharging power control value required by the current vehicle (i.e., the vehicle currently to be charged) as the charging and discharging power control value of the target vehicle corresponding to the current target charging and discharging period. If they are not equal, adjust the charging and discharging power control value of the current target charging and discharging period, and use the adjusted charging and discharging power control value of the vehicle as the charging and discharging power control value of the vehicle in the current target charging and discharging period;

[0135] A. Through remote start, four charging and discharging control modes are realized: single charging, single discharging, platform hosting, and user-defined;

[0136] B. Local startup realizes two charging and discharging control modes: single charging and single discharging;

[0137] C. Local startup realizes the charging and discharging control mode hosted by the platform.

[0138] D. Local startup realizes user-defined charge and discharge control mode. Figure 2 As shown, the above scenario A specifically includes the following steps:

[0139] Step A 1. After the charging gun is inserted into the vehicle, the user uses the APP (installed in the smartphone) to scan the preset startup QR code;

[0140] Step A2: The APP prompts the user to select a charge and discharge mode (the APP displays four options: single charge, single discharge, platform hosting, and user-defined). If the user selects the user-defined mode, the APP also prompts the user to enter the charge and discharge load control curve information;

[0141] Step A3: The network terminal prompts the user to select the minimum SOC for discharging, the maximum SOC for charging, and the time to pick up the vehicle;

[0142] Step A4: After the user has made his selection, he clicks the start charging and discharging button to send a start command to the charging platform, which then sends the command to the charging pile.

[0143] Step A5: After receiving the start command, the charging pile starts in charging mode. After successful start, the vehicle information is sent to the charging platform; the vehicle information includes the vehicle SOC (remaining power) and BMS (battery management system) information;

[0144] Step A6: The charging platform generates charging and discharging load control curve information and sends it to the charging pile;

[0145] Step A7: Within 2 minutes after the charging pile is successfully started, before receiving the charge and discharge load control curve information, the voltage is output at the vehicle's required voltage and the current is output at zero current; if the charging pile still does not receive the charge and discharge load control curve information 2 minutes after the charging pile is successfully started, the charging is performed at the vehicle's required voltage and required current;

[0146] Step A8: After receiving the charge and discharge load control curve information, the charging pile retrieves the charge and discharge time period at the current time, then extracts the charge and discharge mode and charge and discharge power control value of the retrieved charge and discharge time period from the charge and discharge load control curve information, and charges and discharges the vehicle according to the extracted charge and discharge mode and charge and discharge power control value; then, it retrieves in real time whether the charge and discharge time period at the current time has changed, and if it has changed, extracts the charge and discharge mode and charge and discharge power control value of the changed charge and discharge time period, and performs charge and discharge of the vehicle in the changed charge and discharge time period according to the extracted charge and discharge mode and charge and discharge power control value.

[0147] For example, the current charging power control value is 30kW for charging, and the monitoring period changes. The changed period requires the charging and discharging mode to be discharge, and the discharge power control value is 10kW, then the power module is re-controlled to perform a 10kW discharge action. Step A9: The charging pile monitoring reaches the stop condition, such as: reaching the pick-up time, the vehicle actively terminates, or the charging pile fails, and the charging and discharging action is stopped.

[0148] Step A10: Considering the differences among vehicles and the inaccuracy of the load control curve generation, during the charging and discharging process of each time period, the vehicle may reach the minimum or maximum SOC limit set by the user even though the time period has ended. In combination with the charging and discharging requirements corresponding to each time period, the corresponding charging input or discharging output action can be performed with zero current control.

[0149] Step A11: If the charging pile receives new charge and discharge load control curve information during the charge and discharge control process, the latest data shall prevail, that is, the charge and discharge of the corresponding vehicle shall be controlled according to the latest received charge and discharge load control curve information.

[0150] like Figure 5 As shown, the above scenario B specifically includes the following steps:

[0151] Step B 1. After the charging gun is inserted into the vehicle, the user uses the near field interaction method (local card swiping or local Bluetooth activation) to perform local authentication activation;

[0152] Step B2: After authentication, the charging pile screen prompts the user to select the charging and discharging mode (single charging, single discharging, platform hosting, user-defined);

[0153] Step B3: After the user selects the single charge or single discharge mode, the charging pile screen prompts the user to select the minimum discharge SOC, the maximum charge SOC and the time to pick up the car. Specifically, when the user selects the single charge mode, the charging pile screen prompts the user to select the maximum charge SOC and the time to pick up the car; when the user selects the single discharge mode, the charging pile screen prompts the user to select the minimum discharge SOC and the time to pick up the car;

[0154] Step B4: After the selection is completed, the user clicks the start button to start the device;

[0155] Step B5: The charging pile is started in charging or discharging mode directly according to the single charging mode or single discharging mode selected by the user;

[0156] Step B6, single charge mode, the charging pile outputs the maximum charging SOC, the minimum discharging SOC, the vehicle pick-up time, and the vehicle required voltage and current according to the user input; single discharge mode, the charging pile controls the voltage to be always less than the required voltage, and inputs the charging pile according to the required current;

[0157] Step B7: When the charging pile monitoring reaches the stop condition, for example, reaching the SOC lower limit or upper limit, the vehicle actively terminates, or the charging pile fails, the charging and discharging action is stopped.

[0158] like Figure 3 As shown, the above usage scenario C specifically includes the following steps:

[0159] Step C 1. After the charging gun is inserted into the vehicle, the user uses the near field interaction method (local card swiping or local Bluetooth activation) to perform local authentication and activation;

[0160] Step C2: After authentication, the charging pile screen prompts the user to select the charging and discharging mode (single charging, single discharging, platform hosting, user-defined);

[0161] Step C3: The user selects the platform hosting mode. After the user selects the platform hosting mode, the charging pile screen prompts the user to select user configuration information: minimum SOC for discharge, maximum SOC for charge, and pick-up time;

[0162] Step C4: After the selection is completed, the user clicks the start charging and discharging button to start the charging pile;

[0163] Step C5: The charging pile is started in charging mode. After successful startup, the user configuration information and vehicle information (including SOC, BMS information, etc.) are sent to the charging platform;

[0164] Step C6: The charging platform generates charging and discharging load control curve information and sends it to the charging pile;

[0165] Step C7: within 2 minutes after the charging pile is successfully started, before receiving the charge and discharge load control curve information, output voltage at the vehicle required voltage and output current at zero current; if the charging pile still does not receive the charge and discharge load control curve information 2 minutes after the charging pile is successfully started, charge at the vehicle required voltage and required current;

[0166] Step C8: After receiving the charge and discharge load control curve information, the charging pile retrieves the charge and discharge time period at the current time, then extracts the charge and discharge mode and charge and discharge power control value of the retrieved charge and discharge time period from the charge and discharge load control curve information, and charges and discharges the vehicle according to the extracted charge and discharge mode and charge and discharge power control value; then, it retrieves in real time whether the charge and discharge time period at the current time has changed, and if it has changed, extracts the charge and discharge mode and charge and discharge power control value of the changed charge and discharge time period, and performs charge and discharge of the vehicle in the changed charge and discharge time period according to the extracted charge and discharge mode and charge and discharge power control value.

[0167] For example, the current charging power control value is 30kW for charging, and the monitoring time period changes. The changed time period requires the charging and discharging mode to be discharge, and the discharge power control value is 10kW, then the power module is controlled again to perform a 10kW discharge action.

[0168] Step C9: When the charging pile monitoring reaches the stop condition, for example, the vehicle pick-up time is reached, the vehicle terminates actively, or the charging pile fails, the charging and discharging action is stopped;

[0169] Step C 10. Considering the differences among vehicles and the inaccuracy of the load control curve generation, it is possible that the minimum or maximum SOC limit is reached, but the current period requires a discharge or charge action, so the input or output action is performed at zero current;

[0170] Step C 11. If new charge and discharge load control curve information is received during the charge and discharge process, the latest data shall prevail.

[0171] like Figure 4 As shown, the above scenario D specifically includes the following steps:

[0172] Step D 1. After the charging gun is inserted into the vehicle, the user uses the near field interaction method (local card swiping or local Bluetooth activation) to perform local authentication activation;

[0173] Step D2, after authentication is passed, the charging pile screen prompts the user to select a charge and discharge mode (single charge, single discharge, platform hosting, user-defined), the user selects the user-defined mode, and after the user selects the user-defined mode, the charging pile screen prompts the user to configure the charge and discharge load control curve information;

[0174] Step D3: After the user configures the charge and discharge load control curve information, the charging pile screen prompts the user to select the minimum discharge SOC, the maximum charge SOC and the pick-up time;

[0175] Step D4: After the selection is completed, the user clicks the start charging and discharging button on the charging pile screen to start the charging pile;

[0176] Step D5: The charging pile is started in charging mode. After successful startup, charging and discharging are performed according to the charging and discharging load control curve information configured by the user;

[0177] Step D6: After receiving the charge and discharge load control curve information, the charging pile retrieves the charge and discharge time period at the current time, then extracts the charge and discharge mode and charge and discharge power control value of the retrieved charge and discharge time period from the charge and discharge load control curve information, and charges and discharges the vehicle according to the extracted charge and discharge mode and charge and discharge power control value; then, it retrieves in real time whether the charge and discharge time period at the current time has changed, and if it has changed, extracts the charge and discharge mode and charge and discharge power control value of the changed charge and discharge time period, and performs charge and discharge of the vehicle in the changed charge and discharge time period according to the extracted charge and discharge mode and charge and discharge power control value.

[0178] For example, the current charging power control value is 30kW for charging, and the monitoring time period changes. The changed time period requires the charging and discharging mode to be discharge, and the discharge power control value is 10kW, then the power module is controlled again to perform a 10kW discharge action.

[0179] After receiving the charge and discharge load control curve information, the charging pile retrieves the charge and discharge load control curve information period of the current time, and extracts the charge and discharge mode and charge and discharge power of the period when changes occur, and performs the charge and discharge actions in sequence. For example, the current charging power control value is 30kW for charging, and the monitoring period changes. The charging and discharging mode of the changed period is required to be discharge, and the discharge power control value is 10kW, then the power module is re-controlled to perform a 10kW discharge action.

[0180] Step D7: When the charging pile monitors and reaches the stop condition, such as when the vehicle pick-up time arrives, the vehicle terminates actively, or the equipment fails, the charging and discharging action is stopped.

[0181] Step D8: Considering the differences among vehicles and the inaccuracy of the load control curve generation, it is possible that the minimum or maximum SOC limit is reached, but the current period requires discharge or charge action, so the input or output action is performed with zero current.
