[0023] Currently, the commonly implemented charging method for electric vehicles has the problem of low charging rate of the battery at low temperatures or at the end of charging (high charge state).

[0024] In view of the above problems, the embodiment of the present application provides a vehicle charging control method, which can monitor the charging current value when the vehicle is charging, and send a pulse charging request to the electric drive system when the battery system determines that the charging current value meets the first target trigger condition, so that the electric drive system performs the pulse charging task according to the pulse charging request, thereby providing a discharge pulse through the deep coordination of the battery system and the electric drive system to eliminate charging polarization. It is beneficial to improve the charging rate, thereby achieving a breakthrough in the performance of low temperature and charging terminal.

[0025] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0026] Figure 1 It is a flow chart of a vehicle charging control method shown in an embodiment of the present application.

[0027] See also Figure 1 , a vehicle charging control method, the method comprising: Step 101 : When the vehicle is being charged, the battery system monitors the charging current value.

[0028] During the charging process of an electric vehicle, the charging rate will decrease at the end of the charging period (high charge state) and in a low temperature environment. The charging rate decrease will be manifested as a decrease in the charging current value. In this step, the battery system can monitor the charging current value.

[0029] Step 102 : In response to the battery system determining that the charging current value meets the first target trigger condition, the battery system sends a pulse charging request to the electric drive system.

[0030] Pulse charging is the process of charging a battery with intermittent (non-continuous) current pulses, where each pulse consists of a short period of high current and a longer period of power failure (or low current).

[0031] In this step, the first target trigger condition refers to the charging current value monitored by the battery system being less than a preset threshold value. The threshold value can be set according to the vehicle electric drive performance, such as the threshold value = 80% of the maximum discharge capacity of the electric drive.

[0032] In this step, for example, the battery system can determine whether pulse charging is required according to the current of its own map.

[0033] For example, when the charging current value is less than the set threshold, pulse charging is required, and the battery system sends a pulse charging request to the electric drive system. For example, during the fast charging process, the charging current value will decrease in a low temperature environment or at the end of charging. When the charging current value is detected to be less than the threshold, the fast charging mode is switched to the pulse charging mode to request the charging pile to output current.

[0034] Step 103 , in response to the electric drive system receiving the pulse charging request, the electric drive system performs a pulse charging task according to the pulse charging request.

[0035] In this step, the electric drive system of the entire vehicle can be reused. After receiving the pulse charging request, the electric drive system performs the pulse charging task, thereby providing a discharge pulse to eliminate charging polarization.

[0036] The vehicle charging control method of the embodiment of the present application can monitor the charging current value when the vehicle is charging, and send a pulse charging request to the electric drive system when the battery system determines that the charging current value meets the first target trigger condition, so that the electric drive system performs the pulse charging task according to the pulse charging request, thereby providing a discharge pulse through the deep coordination of the battery system and the electric drive system to eliminate charging polarization. This is conducive to improving the charging rate, thereby achieving a performance breakthrough in low temperature and charging terminals.

[0037] In some embodiments, the electric drive system performs a pulse charging task according to a pulse charging request, including: determining a rotor position angle of the motor; the electric drive system controls the on and off of a bridge arm according to the rotor position angle and the pulse charging request to perform the pulse charging task.

[0038] It can be understood that the electric drive system in this example can control the on-off of the bridge arm to perform the pulse charging task according to its own state such as the rotor position angle and the pulse charging request. The reason for determining the rotor position angle of the motor is to avoid generating torque, thereby avoiding the jitter caused by the torque. By controlling the on-off of the bridge arm, the rotor angle approaching zero torque is achieved to control the current direction in the pulse charging task, so that the magnetic field generated by the current approaches to be parallel to the magnetic field of the rotor itself.

[0039] The bridge arm on-off refers to the on and off state control, the purpose of which is to change the flow path of the current in the bridge arm.

[0040] Figure 2 is a pulse charging topology diagram shown in the embodiment of the present application. Figure 2 , when the electric drive system performs pulse discharge on the battery system, such as through Figure 2 The middle bridge arm is turned off to control the current direction, such as the current flows through Q1 into Q4 or Q6, or Q3 into Q2 or Q6, etc.

[0041] For example, any of Q1 to Q6 may have two states, 0 for off and 1 for on, and there are 6 bits, that is, 2 to the sixth power states. For example, Q1 is off and Q2 is on, Q3 is off and Q4 is on, Q5 is off and Q6 is on, thus forming mutual exclusion. One bridge arm is one bit, that is, 8 states, which can be represented by 000, 001, and 010 respectively. Then, according to the rotor angle, one of the 8 vectors is selected to control the on and off of the bridge arm to determine the direction of current flow.

[0042] The vehicle charging control method of the embodiment of the present application can avoid the generation of torque by controlling the on-off of the bridge arm to determine the direction of current flow, thereby avoiding the jitter caused by the torque.

[0043] In some embodiments, the pulse charging request includes an interval period parameter, a bus pulse current amplitude parameter, and a bus pulse current duration parameter; the electric drive system controls the on-off of the bridge arm to perform the pulse charging task according to the rotor position angle and the pulse charging request, including: the electric drive system determines the duty cycle of the on-off of the bridge arm according to the interval period parameter, the bus pulse current amplitude parameter, and the bus pulse current duration parameter, and performs the pulse charging task according to the duty cycle.

[0044] The interval period parameters can be preset based on the battery chemical characteristics, the bus pulse current amplitude parameters can be adjusted and determined according to the output capacity of the charging pile, and the bus pulse current duration parameters can be dynamically optimized and determined.

[0045] In the circuit, the "duty cycle of the bridge arm on and off" refers to the proportion of the time that a bridge arm (branch) in the bridge circuit is in the on state to the entire signal cycle. It is a key parameter for controlling the switching behavior of the bridge arm and directly affects the output characteristics of the circuit (such as voltage, current, power, etc.).

[0046] The duty cycle of the bridge arm on and off = duration of bus pulse current / interval period × 100%.

[0047] The duty cycle describes the proportion of the time that the bridge arm is "powered on" and "powered off" in a complete cycle. For example, if the duty cycle is 50%, it means that the bridge arm is powered on for 1 second and powered off for 0.5 seconds. If the duty cycle is 100%, it means that the bridge arm is continuously turned on; if it is 0%, it means that it is always turned off.

[0048] Figure 3 is a schematic diagram of a pulse discharge current shown in an embodiment of the present application, Figure 4 is a schematic diagram of the current waveform shown in the embodiment of the present application, see Figure 3 and Figure 4 The electric drive system periodically outputs pulse discharge current according to the request of the battery system. The bus current waveform of the battery system is superimposed into a pulse charging current waveform based on the output of the charging pile and the pulse discharge of the electric drive system.

[0049] For example, the interval period parameter is 1 second, the bus pulse current amplitude parameter is 200A, and the bus pulse current duration parameter is 0.1 second. The electric drive system obtains the above three parameter information, performs discharge according to its own rotor position angle, and confirms which vector performs 0.1 second discharge. The bus pulse current amplitude is realized by the duty cycle to achieve an effective current of 200A.

[0050] The electric drive system determines the duty cycle of the bridge arm on and off according to the actual request and its own characteristics, and performs the pulse charging task according to the duty cycle to achieve a current waveform close to the expected current waveform of the battery system.

[0051] Figure 5 It is another flow chart of the vehicle charging control method shown in an embodiment of the present application.

[0052] See also Figure 5 , the vehicle charging control method further includes: Step 501: The vehicle controller monitors a first temperature value corresponding to the battery system and a second temperature value corresponding to the electric drive system.

[0053] Step 502 , in response to the vehicle controller determining that the first temperature value and the second temperature value meet the second target trigger condition, the vehicle controller executes a heating task of the battery system.

[0054] The first temperature value refers to the temperature value of the battery, and the second temperature value refers to the water temperature value of the electric drive circuit.

[0055] The vehicle controller monitors the first temperature value corresponding to the battery system and the second temperature value corresponding to the electric drive system, and when the vehicle controller determines that the first temperature value and the second temperature value meet the second target trigger condition, the heating task of the battery system is executed, thereby utilizing the waste heat of the electric drive to heat the battery, allowing the battery to change the low temperature environment, which is conducive to further improving the charging rate.

[0056] In some embodiments, in response to the vehicle controller determining that the first temperature value and the second temperature value meet the second target trigger condition, the vehicle controller performs a heating task for the battery system, including: when the first temperature value is respectively less than the second temperature value and the threshold, determining that the first temperature value and the second temperature value meet the second target trigger condition; and connecting the circuit of the battery system in series with the circuit of the electric drive system.

[0057] It is understandable that a large amount of heat will be generated when the electric drive system performs pulse charging tasks. In order to effectively utilize the waste heat, waste heat heating coordination can be enabled. The vehicle controller monitors the temperature of the battery and the water temperature of the electric drive circuit. When the water temperature of the electric drive circuit is higher than the temperature of the battery, and the temperature of the battery is lower than the preset threshold, the circuit of the battery system can be connected in series with the circuit of the electric drive system, and the water pumps of the battery system and the electric drive system circuit can be turned on at the same time, so as to use the waste heat of the electric drive system to heat the battery and avoid heat waste.

[0058] In some embodiments, the vehicle charging control method also includes: when the electric drive system performs a pulse charging task, the electric drive system monitors the working status; in response to the electric drive system determining that the working status does not meet the requirements for continuing to perform the pulse charging task, the electric drive system sends the working status to the bus to stop performing the pulse charging task.

[0059] It is understandable that when the electric drive system performs the pulse charging task, the electric drive system also needs to monitor its own working status, such as whether there is a fault and its own temperature information. It further determines whether its own status meets the execution of the pulse charging task and feeds back to the bus. If the electric drive system fails, the electric drive system sends the working status to the bus to stop executing the pulse charging task.

[0060] In order to better understand the present application, the content of the present application is further explained below in conjunction with the embodiments, but the present application is not limited to the following embodiments.

[0061] Initialization determines whether each vehicle system meets the conditions for pulse charging, such as initialization of each electronic control unit ECU, and response to electronic control unit ECU failure, including battery system, electric drive system, vehicle thermal management system, and vehicle control system.

[0062] After initialization and fault detection, the battery system determines whether pulse charging is required based on the current of its own fast charge map, bus current status, and electric drive system operating mode. When pulse charging is required, the electric drive system is requested to perform a discharge pulse current, which may include three parameters: interval period parameter, bus pulse current amplitude parameter, and bus pulse current duration parameter.

[0063] The electric drive system executes pulse discharge according to the request from the battery system to realize the bus pulse charging waveform required by the battery system; at the same time, it determines whether its own working state meets the requirements for pulse discharge and feeds back to the bus. The battery system collects the bus current value in real time to determine whether it has entered the pulse charging state. If the electric drive system feedback shows that it has not entered the pulse charging working state or the bus current actually shows that it has not entered the pulse charging state or does not meet the requirements for entering pulse charging, it exits the pulse charging map and switches to the fast charging map.

[0064] The vehicle control system determines whether the vehicle's thermal management system meets the requirements for pulse charging and decides whether to connect the waste heat generated by the electric drive system to the battery system circuit in series. For example, the waste heat generated by the electric drive system is transferred to the vehicle's water circuit, and the battery system is heated by connecting the battery system circuit and the electric drive system circuit in series.

[0065] Through the vehicle charging control method of the embodiment of the present application, it is possible to achieve a charging efficiency of 40% higher than that of traditional fast charging in an actual measured -20°C environment, and a charging speed of 30% higher than that of traditional fast charging at the end of charging (such as 90%-100% power), which is beneficial to extending battery life and contributing to the promotion of electric vehicles.

[0066] Corresponding to the aforementioned application function implementation method embodiment, the present application also provides a vehicle charging control system, an electronic device and corresponding embodiments.

[0068] See also Figure 6 The vehicle charging control system 600 of this embodiment includes a battery system 610 and an electric drive system 620 .

[0069] The battery system 610 is used to monitor the charging current value and send a pulse charging request to the electric drive system when it is determined that the charging current value meets the first target trigger condition.

[0070] The electric drive system 620 is used to perform a pulse charging task according to the pulse charging request when a pulse charging request is received.

[0071] The first target trigger condition refers to that the charging current value monitored by the battery system is less than a preset threshold.

[0072] During the charging process of electric vehicles, the charging rate will decrease at the end of charging (high charge state) and in low temperature environments. The reduced charging rate will be manifested as a reduced charging current value. The battery system can monitor the charging current value. When the charging current value is less than the set threshold, pulse charging is required, and the battery system sends a pulse charging request to the electric drive system. The electric drive system of the whole vehicle is reused. After receiving the pulse charging request, the electric drive system performs the pulse charging task, thereby providing a discharge pulse to eliminate charging polarization and improve charging efficiency.

[0073] The vehicle charging control system of the embodiment of the present application can improve the charging rate and help achieve performance breakthroughs in low temperature and charging terminals.
