Description

Technical Field

[0001] The present invention relates to the field of charging technology, and in particular to a vehicle charging management method and related equipment. Background Art

[0002] At present, there are generally two ways to charge electric vehicles, namely fast charging and slow charging. The current slow charging is to convert the low-current AC power output by the charging pile through the on-board charger OBC, and input the converted low-current DC power into the vehicle's power battery. The charging power is determined by the OBC power, and there are usually several power modes of 7kW, 11kW and 22kW. When fast charging, the AC-DC converter is connected to the charging pile, and the charging pile can directly output DC power. Since the converter is external to the charging pile, the output charging power is greater. Compared with the AC-DC conversion through the OBC built into the vehicle, the required charging time is shorter.

[0003] However, since fast charging will cause certain losses to the battery, users usually choose slow charging when it is not necessary, so the low current charging function is essential. However, the current slow charging of electric vehicles is still achieved through the on-board OBC, which cannot realize the arbitrary switching of charging power. In addition, the on-board OBC has the problems of high installation cost, large space occupation, fixed output power, and inability to flexibly adjust. Summary of the invention

[0045] The embodiments will be described in detail below, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following embodiments do not represent all implementation methods consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims. In the several embodiments provided in the embodiments of the present application, it should be understood that the disclosed devices and methods can also be implemented in other ways, and the device embodiments described below are merely exemplary.

[0046] The present application provides a vehicle charging management method, comprising:

[0047] Step S110: In response to a slow charging start instruction of the vehicle, the slow charging power of the vehicle is obtained, wherein the slow charging is a charging operation with a charging power lower than 30 kW.

[0048] It should be noted that, since charging with a charging power lower than 30 kW takes a longer time, the charging operation with a charging power lower than 30 kW can be determined as slow charging.

[0049] Exemplarily, the above-mentioned slow charging instruction can be issued when the vehicle is connected to a charging power source, or it can be a start-up instruction issued by the driver to switch from fast charging to slow charging based on the driver's usage needs during the charging process of the vehicle. The above-mentioned slow charging can be set based on a preset maximum slow charging power, and can be divided into different charging power levels based on different charging times.

[0050] Step S120: Obtain the output power of the charging pile.

[0051] For example, the vehicle's BMS battery management system can establish a communication connection with the charging pile to obtain the output power of the charging pile. It can also be determined by the vehicle's BMS battery management system by obtaining the input power through the power interface when the vehicle is connected to a power source.

[0052] Step S130: When the output power of the charging pile is greater than the slow charging power, a power adjustment instruction is sent to the charging pile, where the power adjustment instruction includes the slow charging power.

[0053] For example, the vehicle's BMS battery management system can establish a communication connection with the charging pile, and send a signal to the charging pile to adjust the output power to slow charging power. The vehicle's BMS battery management system can also establish a communication connection with the smart terminal of the driver of the vehicle to which it belongs, and notify the driver to manually adjust the output power of the charging pile.

[0054] According to some embodiments, when the output power of the charging pile is greater than the slow charging power, sending a power adjustment instruction to the charging pile includes:

[0055] Obtain the type information of the above charging pile;

[0056] Based on the type information of the charging pile, determining the power change threshold information of the charging pile;

[0057] Based on the power change threshold information of the charging pile, a power adjustment instruction is sent to the charging pile, and the power adjustment instruction also includes the power change threshold information of the charging pile.

[0058] Exemplarily, the target charging pile can be imaged through the vehicle's on-board imaging system. Based on the image acquisition information, at least one of the nameplate and appearance of the charging pile can be identified through an image recognition algorithm to obtain the type information of the charging pile. The vehicle's BMS battery management system can also establish a communication connection with the charging pile to obtain the type information of the charging pile, wherein the above-mentioned type information may include the maximum instantaneous output current, maximum instantaneous output power, maximum instantaneous current, maximum instantaneous power, safe operating current and safe operating power of the charging pile. Based on the above-mentioned type information of the charging pile, the power change threshold of the charging pile can be determined.

[0059] By determining the power change threshold of the charging pile, a power adjustment instruction can be issued to the charging pile based on the above power change threshold to prevent the instantaneous output current and / or instantaneous output power of the charging pile from exceeding the change threshold of the charging pile, causing damage to the charging pile, causing danger and property loss.

[0060] According to some embodiments, the sending of a power adjustment instruction to the charging pile based on the power change threshold information of the charging pile includes:

[0061] Determining a target power adjustment rate of the charging pile based on the power change threshold information of the charging pile and the slow charging power of the vehicle;

[0062] Based on the target power regulation rate of the charging pile, a power regulation instruction is sent to the charging pile, and the power regulation instruction also includes the target power regulation rate of the charging pile.

[0063] Exemplarily, the power adjustment rate range of the charging pile can be determined by the power change threshold of the charging pile and the slow charging power of the vehicle. The power adjustment time range of the charging pile can be determined based on the power adjustment rate range of the charging pile. For example, if the power change threshold of the charging pile is 5kW, the output power of the charging pile is 200kW, and the slow charging power of the vehicle is 25kW, then the power adjustment rate range of the charging pile is 0.1~5kW / s, and the power adjustment time range of the charging pile is 35s~1750s. The above power adjustment time range can be sent to the vehicle management system, and the driver of the vehicle can independently set the target power adjustment time based on the above time range. The target power adjustment rate of the charging pile can be determined by the vehicle's BMS battery management system based on the above target power adjustment time.

[0064] Based on the power change threshold information of the charging pile and the slow charging power of the vehicle, the target power adjustment rate of the charging pile is determined, so that the charging pile can safely and stably adjust the output power and further protect the charging pile.

[0065] According to some embodiments, the method further comprises:

[0066] When the vehicle is in a fast charging state and receives a slow charging start instruction of the vehicle, obtaining a current fast charging power of the vehicle;

[0067] determining a target charging type for the vehicle based on a current fast charging power of the vehicle and a slow charging power of the vehicle;

[0068] Determining a target output power of the charging pile based on a target charging type of the vehicle;

[0069] Based on the target output power of the charging pile, a power adjustment instruction is sent to the charging pile, and the power adjustment instruction also includes the target output power of the charging pile.

[0070] Since the charging power of fast charging will change according to the charge amount of the power battery, when the battery power reaches the preset power, the fast charging power may be lower than the slow charging power. Therefore, further judgment is needed to determine the target output power of the charging pile, improve the charging quality, and avoid shortening the charging time and the battery protection effect. Frequent switching of the output power of the charging pile may cause damage to the charging pile.

[0071] According to some embodiments, determining the target charging type of the vehicle based on the current fast charging power of the vehicle and the slow charging power of the vehicle includes:

[0072] When the slow charging power is greater than or equal to the current fast charging power, determining the target charging type of the vehicle to maintain the fast charging state of the vehicle;

[0073] When the slow charging power is less than the current fast charging power, determining the target charging type of the vehicle to be switched to the slow charging state;

[0074] The above-mentioned determining the target output power of the above-mentioned charging pile based on the target charging type of the above-mentioned vehicle includes:

[0075] When the target charging type of the vehicle is to maintain the fast charging state of the vehicle, the target output power of the charging pile is the current fast charging power;

[0076] When the target charging type of the vehicle is to switch to the slow charging state, the target output power of the charging pile is the slow charging power.

[0077] By comparing the slow charging power and the current fast charging power, when the slow charging power is greater than or equal to the current fast charging power, it means that the power of the power battery is higher than the preset power, and charging with the current fast charging power is already in a low current charging state. At this time, switching to slow charging will increase the charging power, causing certain damage to the vehicle battery and charging pile. When the slow charging power is less than the current fast charging power, it means that the charging power is large. At this time, switching to slow charging can protect the vehicle battery. Therefore, based on the above slow charging power and the current fast charging power, determining the charging type can improve the protection effect on the battery.

[0078] According to some embodiments, the method further comprises:

[0079] determining a preset response duration for slow charging start and shut-off commands for the above-mentioned vehicle;

[0080] Within the preset response duration after responding to the slow charging start or stop command of the vehicle, no response is given to other charging stop or start commands of the vehicle.

[0081] Exemplarily, the preset response duration of the vehicle's slow charging start and shutoff instructions can be independently set by the driver of the vehicle, or the vehicle's BMS battery management system can collect and analyze the driver's slow charging instruction operation history information, and determine the preset response duration of the vehicle's slow charging start and shutoff instructions based on the above historical information. When the vehicle responds to the slow charging start instruction and starts slow charging, within the preset response duration, if a slow charging shutoff instruction, a fast charging start instruction, etc. is received, the vehicle does not need to respond, and can respond to the first charging instruction received after the preset response duration.

[0082] By setting the preset response duration, it is possible to avoid damage to the charging pile and battery caused by frequent switching of charging states due to incorrect operations, thereby protecting the charging pile and battery and extending their service life.

[0083] According to some embodiments, the method further comprises:

[0084] In response to the charging shutdown instruction of the vehicle, obtaining the initial output power of the charging pile;

[0085] Based on the initial output power of the charging pile, a power adjustment instruction is sent to the charging pile.

[0086] By obtaining the initial output power of the charging pile and adjusting the output power of the charging pile after the vehicle exits the charging state, the output power of the charging pile can be reset for subsequent use.

[0090] The second acquisition module 202 is used to obtain the output power of the charging pile;

[0091] The instruction module 203 is used to send a power adjustment instruction to the charging pile when the output power of the charging pile is greater than the slow charging power, and the power adjustment instruction includes the slow charging power.

[0092] A vehicle charging management device 200 can achieve Figure 1To avoid repetition, the various processes implemented in the method embodiment are not described here.
