The mobile power supply management system is respectively connected with the monitoring module, the charging module and the discharging module and is used for managing and controlling the monitoring module, the charging module and the discharging module.

Referring to fig. 2 and 3, an embodiment of the present invention provides a mobile power supply adjustment control method, where an execution body of the mobile power supply adjustment control method is a mobile power supply management system, and the method mainly includes the following steps:

Step S100: and monitoring the running state of the mobile power supply module based on the power-on signal, wherein the running state comprises a charging state and a discharging state.

It will be appreciated that the mobile power management system involves a whole vehicle domain controller (VCU), a mobile power management system and a water cooling system controller (TMS).

The whole vehicle domain controller (VCU) is a core controller for controlling the whole vehicle, and realizes the management of a mobile power management system, an electric drive system, a water cooling system controller (TMS) and the like through buses or hard wires, and the torque required to be output is calculated mainly according to the real-time electric quantity of the mobile power module, and the low-voltage power on and off of the whole vehicle are controlled.

When a whole vehicle domain controller (VCU) controls low-voltage and high-voltage power on and off of the whole vehicle, the method mainly comprises the following steps: key power-up, dc/ac charging, remote control, and other power-up wake-up modes.

In the power-on process, firstly, the whole vehicle domain controller is awakened by a key signal, a network signal or a charging cc signal hard wire, after the starting, a CAN message for requesting to close an HVIL loop enabling line and a necessary 12V low-voltage relay is sent, the state of the HVIL loop is monitored, and then the DCU, the DC/DC and the mobile power management system are awakened.

And then the whole vehicle domain controller requests to close the main relay, the mobile power management system sequentially closes the main negative relay and the pre-charging relay, after the bus voltage reaches the threshold value, the pre-charging is judged to be successful, then the main positive relay is closed, the pre-charging relay is opened, and the high-voltage power-on is completed at the moment.

For example, when the whole-vehicle-domain controller receives a key signal, the whole-vehicle-domain controller is firstly awakened and starts self-checking, the self-checking content comprises whether a fault is reported in the power-on process, whether the low-voltage power storage source voltage is in a normal range and the like, after the self-checking is passed, a control node of the local area network is awakened through a CAN message or a KL15 hard wire, namely the whole-vehicle-domain controller wakes a water-cooling system controller (TMS) through the hard wire, the water-cooling system controller is communicated with a mobile power management system and a whole-vehicle-domain controller (VCU) through a power CAN, and meanwhile, the water-cooling system controller is communicated with a compressor, a water pump, an electronic fan, a DC/DC and other water-cooling units through an internal CAN. The mobile power supply management system sends a control instruction to the water cooling system controller, and the water cooling system controller controls each part of the water cooling unit to execute corresponding actions so as to realize cooling of the mobile power supply module.

In a normal power-down flow, when the whole-vehicle-domain controller detects that a key signal is closed, a hard-wire signal is closed or a network wake-up signal is stopped, the whole-vehicle-domain controller immediately requests a DCU to leave a working mode, a power device rapidly reduces power, then the whole-vehicle-domain controller requests a DC/DC to leave the working mode, then the whole-vehicle-domain controller requests a mobile power management system to disconnect a high-voltage relay, after the mobile power management system finishes responding, the whole-vehicle-domain controller disconnects an HVIL loop and a low-voltage relay, and each node enters the power-down dormancy flow.

It should be noted that, the water cooling system controller is also electrically connected with a sensor, and the sensor may include a water inlet temperature sensor, a water outlet temperature sensor, a liquid level sensor, an evaporation temperature sensor or a ring temperature sensor, etc., and the water outlet temperature sensor is used for monitoring the water outlet temperature of the water cooling pipeline. The mobile power supply management system is also electrically connected with a heating relay, and the heating relay is used for controlling the heating assembly to work so as to heat the mobile power supply module.

Step S200: and when the running state is determined to be the charging state, entering a corresponding charging working mode according to the temperature range of the mobile power supply module.

It can be understood that the temperature of the mobile power supply module can change in the charging process, and the mobile power supply management system selects to enter different charging working modes according to the temperature range of the mobile power supply module. For example, the lowest temperature value of the mobile power module is denoted as Tmin, the highest temperature value of the mobile power module is denoted as Tmax, and when Tmin is less than 3 ℃ and Tmax is less than 40 ℃, the mobile power management system enters a pure heating mode. When Tmin is more than or equal to 3 ℃ and Tmin is less than 15 ℃ and Tmax is less than 40 ℃, the mobile power management system enters a charging-while-heating mode. When Tmin is more than or equal to 15 ℃ or Tmax is more than or equal to 40 ℃, the mobile power management system advances and retreats from the heating mode to enter the pure charging mode. When Tmin is more than or equal to 15 ℃ and Tmax is more than or equal to 40 ℃, the mobile power management system enters a cooling-while-charging mode.

Step S300: and when the running state is determined to be a discharging state and the speed of the vehicle meets the preset running condition, entering a corresponding discharging working mode according to the temperature range of the mobile power supply module.

It can be understood that the temperature of the mobile power supply module also changes during the discharging process, but unlike the charging process described above, when the mobile power supply module is determined to discharge, it is necessary to determine whether the vehicle speed of the vehicle satisfies the preset operating condition, and when the vehicle speed of the vehicle satisfies the preset operating condition, the mobile power supply management system selects to enter different discharging modes according to the temperature range of the mobile power supply module. The device can ensure that the mobile power supply module is accurately cooled in the driving process of the vehicle, avoid the cooling unit for starting the mobile power supply module to cool the mobile power supply module in the stopping process, avoid the starting of the cooling unit or the heating system when the cooling unit or the heating system does not need to work, reduce the energy consumption and the working time of the mobile power supply management system to a certain extent, and prolong the service life of the cooling unit and the endurance mileage of the whole vehicle.

For example, when Tmin is less than or equal to 3 ℃ and Tmax is less than or equal to 40 ℃, the mobile power management system enters a discharge-while-heating mode; continuously heating, and when Tmin is more than or equal to 3 ℃ or Tmax is more than or equal to 40 ℃, withdrawing the mobile power management system from heating, and entering a normal discharge mode; when Tmin is more than or equal to 3 ℃ and Tmax is more than or equal to 40 ℃, the mobile power management system enters a discharge-while-refrigeration mode.

According to the mobile power supply regulation control method provided by the embodiment of the invention, the running state of the mobile power supply module is monitored based on the power-on signal; when the running state is determined to be a charging state, entering a corresponding charging working mode according to the temperature range of the mobile power supply module; and when the running state is determined to be a discharging state and the speed of the vehicle meets the preset running condition, entering a corresponding discharging working mode according to the temperature range of the mobile power supply module. The system can carry out refined control aiming at different working modes (namely different working conditions), not only can improve the reliability and the safety of the mobile power supply module, but also can prolong the service life of the cooling unit, and avoid the starting of the cooling unit or the heating system in the mobile power supply management system when the cooling unit or the heating system does not need to work so as to reduce the energy consumption and the working time of the mobile power supply management system.

Optionally, referring to fig. 4, fig. 4 is a schematic flow chart of driving control provided in an embodiment of the present invention. In some embodiments of the present invention, when determining that the operation state is the discharge state and the vehicle speed satisfies the preset operation condition, the method includes:

Step S301: and when the running state is determined to be the discharging state, acquiring the charge proportion of the mobile power supply module.

Step S302: when the charge ratio of the mobile power supply module is larger than or equal to the preset ratio, whether the speed of the vehicle meets the preset operation condition or not is monitored, and the speed of the vehicle is determined to meet the preset operation condition.

After the traveling crane is at high voltage, the mobile power management system continuously detects the charge ratio (SOC) of the mobile power module, when the charge ratio of the mobile power module is lower than 20%, the traveling crane is forbidden to heat, and meanwhile, the mobile power management system continuously detects the speed of the vehicle.

In some embodiments of the present invention, monitoring whether a vehicle speed of a vehicle satisfies a preset operating condition and determining that the vehicle speed of the vehicle satisfies the preset operating condition includes:

step S303: determining that the speed of the vehicle reaches a first preset speed for the first time, and monitoring whether a second speed of the vehicle in a preset time is lower than the second preset speed;

Step S304: the determining that the speed of the vehicle meets the preset running condition is as follows: the second vehicle speed within the preset time is lower than the second preset vehicle speed.

When the speed of the vehicle reaches 20km/h for the first time, continuously monitoring whether the second vehicle speed of the vehicle in the preset time is lower than the second preset speed, and when the speed of the vehicle is higher than 1km/h for 5 minutes, monitoring the temperature of the mobile power supply module by the mobile power supply management system, and entering a corresponding discharging working mode according to the temperature range of the mobile power supply module.

When the vehicle speed of the vehicle is less than 20km/h for the first time, that is, before the vehicle speed of the vehicle is less than 20km/h, the running heating or cooling is prohibited. In the process of power-on circulation, when the speed of the vehicle lasts for 5 minutes and is lower than 1km/h, the vehicle is in a parking stop state or has a parking trend, and the heating or cooling of the vehicle is stopped. Ensure that the vehicle is in driving in-process, cool down to portable power source module accurately, avoid stopping the cooling unit of in-process start portable power source module to cool down to portable power source module, can avoid cooling unit or heating system to start when need not the during operation, reduce portable power source management system's energy consumption and working length to a certain extent to life-span and the continuation of journey mileage of whole car of extension cooling unit.

With continued reference to fig. 4, in some embodiments of the present invention, entering a corresponding discharge operation mode according to a temperature range of the mobile power module includes:

when the minimum temperature value of the mobile power supply module is smaller than or equal to a first preset temperature value and the maximum temperature value of the mobile power supply module is smaller than or equal to a second preset temperature value, a discharge-while-heating working mode is entered;

When the minimum temperature value of the mobile power supply module is larger than or equal to a first preset temperature value or the maximum temperature value of the mobile power supply module is larger than or equal to a second preset temperature value, a normal discharge working mode is entered;

And when the lowest temperature value of the mobile power supply module is greater than or equal to a first preset temperature value and the highest temperature value of the mobile power supply module is greater than or equal to a second preset temperature value, entering a refrigeration and discharge working mode.

Specifically, when Tmin is less than or equal to 3 ℃ and Tmax is less than or equal to 40 ℃, the mobile power management system enters a discharge-while-heating mode, which is shown by the fact that the mobile power management system closes a heating relay, and a discharge-while-heating loop is formed. At this time, the mobile power management system allows the discharge current to be the current lookup value of-8.5A, and the power value is the total current required by heating.

And continuously heating the mobile power supply module, and when the Tmin is more than or equal to 3 ℃ or the Tmax is more than or equal to 40 ℃, exiting the heating mode by the mobile power supply management system, and entering the normal discharging mode.

When Tmin is more than or equal to 3 ℃ and Tmax is more than or equal to 40 ℃, the mobile power management system enters a discharge-while-refrigeration mode.

In some embodiments of the present invention, the mobile power supply adjustment control method further includes:

in a discharge working mode during refrigeration, when a preset fault level exists in the water cooling system controller, judging whether a high-voltage relay in the water cooling system controller is closed or not;

When the high-voltage relay is determined to be closed, sending a target temperature of the mobile power supply module to a water cooling system controller, and monitoring the water outlet temperature of the water cooling unit based on the target temperature and sending the water outlet temperature to a mobile power supply management system by the water cooling system controller;

based on the received outlet water temperature, one of a cooling mode, a self-circulation mode, and a continuation previous setting mode is requested to be set.

Specifically, when the mobile power management system enters a discharge-while-cooling mode, the mobile power management system continuously monitors the fault level of the water cooling system controller, the fault level is divided into three levels, namely, a first-level fault level, a second-level medium fault level and a third-level serious fault level, and when the fault level of the water cooling system controller is monitored to be the second-level or the third-level, the static mobile power management system requests the water cooling system controller to start the corresponding mode.

When the fault level of the water cooling system controller is monitored to be smaller than or equal to a first-level fault level, the first-level fault level is a preset fault level, at the moment, the mobile power management system continuously detects whether the state (TMS_ TMSRLYSTATE) of the high-voltage relay inside the water cooling system controller is closed, and when the state (TMS_ TMSRLYSTATE =0) (not closed state) is reached, the static mobile power management system requests the water cooling system controller to start a corresponding mode.

When tms_ TMSRLYSTATE =1 (closed state). The mobile power management system defaults to send the target temperature BMS_ TARGETTEMP of the mobile power module to the water cooling system controller to be 20 ℃, and simultaneously, the mobile power management system continuously detects the water outlet temperature Tin (TMS_ OutWaterTemp) sent by the water cooling system controller.

When Tin is more than or equal to 15 ℃, the mobile power management system requests the setting mode as follows: the cooling mode, i.e. "BMS request set mode" (bms_ TMSStModeReq) =1 (cooling mode).

When Tin is less than 15 ℃ and Tin is more than or equal to 10 ℃, namely Tin is more than or equal to 10 ℃ and less than 15 ℃, the mobile power management system requests the setting mode to continue the setting before setting. For example, when the previous mode of the water cooling system controller (TMS) is the shutdown mode or the self-circulation mode, the mobile power management system requests the water cooling system controller (TMS) to start the self-circulation (bms_ TMSStModeReq =3: self-circulation mode); when the previous mode of the water cooling system controller (TMS) is the cooling mode, the mobile power management system requests the water cooling system controller (TMS) to continue cooling.

When Tin is less than 10 ℃, the mobile power management system requests to set the mode as follows: the self-circulation mode, namely, the mobile power management system requests the water cooling system controller (TMS) to start self-circulation (bms_ TMSStModeReq =3: self-circulation mode).

In some embodiments of the present invention, it is determined that the maximum temperature value is equal to or less than a third preset temperature, or when a power-down signal is received, the water cooling system controller is requested to enter a standby mode.

When the highest temperature Tmax of the mobile power supply module is less than or equal to 36 ℃ or the mobile power supply management system enters a power-down state, the mobile power supply management system requests the water cooling system controller (TMS) to set the mode as standby (bms_ TMSStModeReq =0).

When the high-voltage contactor inside the water cooling system controller (TMS) is closed, the water cooling system controller (TMS) is in a non-refrigeration state, no under-voltage alarm exists, the SOC is more than 5%, and the water cooling system controller (TMS) has no secondary or tertiary faults, the mobile power management system requests the water cooling system controller (TMS) to start self-circulation and close self-circulation, namely, when the conditions are met, the mobile power management system can request the water cooling system controller (TMS) to start self-circulation and close self-circulation.

The starting conditions are as follows: the highest temperature and the lowest temperature Deltat of the mobile power supply module are more than or equal to 8 ℃.

The closing conditions are: the highest temperature and the lowest temperature Deltat of the mobile power supply module are 0 ℃ or the water cooling system controller (TMS) enters a refrigeration mode or the water cooling system controller (TMS) has secondary or tertiary faults.

In some embodiments of the present invention, when determining that the running state is a charging state, entering a corresponding charging operation mode according to a temperature range of the mobile power module includes:

And when the power-on signal is determined to be a direct current signal, entering a corresponding quick-charging working mode according to the temperature range of the mobile power supply module. The direct current signal charging is commonly called as 'quick charging', the input voltage adopts three-phase four-wire AC 380V plus or minus 15 percent, the frequency is 50Hz, and the output is adjustable direct current. Because the direct current signal is charged by adopting a three-phase four-wire system, the power is larger (60 kw, 120kw, 200kw and even higher), and the charging speed is faster.

And when the power-on signal is determined to be an alternating current signal, entering a corresponding slow charging working mode according to the temperature range of the mobile power supply module. The alternating current signal charging is commonly called as slow charging, when the alternating current signal is charged, the output single-phase/three-phase alternating current is converted into direct current through the vehicle-mounted charger to charge the vehicle-mounted mobile power supply module, the power is generally smaller (7 kw, 22kw, 40kw and other power is available), and the charging speed is generally slower.

Further, when the power-on signal is determined to be a direct current signal, entering a corresponding quick-charging working mode according to the temperature range of the mobile power supply module, including:

And when the lowest temperature value of the mobile power supply module is smaller than the fourth preset temperature value and the highest temperature value of the mobile power supply module is smaller than the fifth preset temperature value, entering a fast-charging pure heating working mode or a fast-charging heating mode.

And when the lowest temperature value of the mobile power supply module is larger than or equal to a fourth preset temperature value or the highest temperature value of the mobile power supply module is larger than or equal to a fifth preset temperature value, entering a pure quick-charging working mode.

And when the lowest temperature value of the mobile power supply module is greater than or equal to a fourth preset temperature value and the highest temperature value of the mobile power supply module is greater than or equal to a fifth preset temperature value, entering a quick charging and heating working mode.

Specifically, the whole vehicle domain controller (VCU) wakes up the water cooling system controller (TMS) after power is obtained, the mobile power management system firstly judges whether a charging signal exists after power is obtained, and if the charging signal exists, the current charging signal is judged to be a direct current charging signal or an alternating current charging signal; if the charging signal is not available, judging whether the vehicle is in a driving state or a parking state currently through the vehicle speed signal and the Ready signal.

When the charging signal is a direct current charging signal, the mobile power management system detects the temperature of the mobile power module after entering a direct current charging flow, the lowest temperature of the mobile power module is recorded as Tmin, and the highest temperature of the mobile power module is recorded as Tmax.

In the case of Tmin < 15℃and Tmax < 40℃being satisfied:

When T_min < 3 ℃ and Tmax < 40 ℃, the mobile power management system enters a pure heating mode. The mobile power management system goes through the power-on process firstly, then controls the heating relay to be closed, and requests the total heating current to be 8.5A.

When T_min is more than or equal to 3 ℃, T_min is less than 15 ℃ and Tmax is less than 40 ℃, the mobile power management system enters a charging and heating mode. The mobile power management system controls the main negative relay to be closed, so that a charging and heating loop is formed, and the current required by the mobile power management system is the current charging current +8.5A (heating demand current).

And continuously heating the mobile power supply module, and when the Tmin is more than or equal to 15 ℃ or the Tmax is more than or equal to 40 ℃, exiting the heating mode by the mobile power supply management system, and entering the pure charging mode.

And when Tmin is more than or equal to 15 ℃ and Tmax is more than or equal to 40 ℃, the mobile power management system enters a cooling and charging mode.

When the mobile power management system enters a charging and refrigerating mode, the mobile power management system continuously monitors the fault level of the water cooling system controller, the fault level is divided into three levels, namely a first-level fault level, a second-level medium fault level and a third-level serious fault level, and when the fault level of the water cooling system controller is monitored to be the second-level or the third-level, the static mobile power management system requests the water cooling system controller to start a corresponding mode.

When the fault level of the water cooling system controller is monitored to be smaller than or equal to a first-level fault level, the first-level fault level is a preset fault level, at the moment, the mobile power management system continuously detects whether the state (TMS_ TMSRLYSTATE) of the high-voltage relay inside the water cooling system controller is closed, and when the state (TMS_ TMSRLYSTATE =0) (not closed state) is reached, the static mobile power management system requests the water cooling system controller to start a corresponding mode.

When tms_ TMSRLYSTATE =1 (closed state). The mobile power management system defaults to send the target temperature BMS_ TARGETTEMP of the mobile power module to the water cooling system controller to be 20 ℃, and simultaneously, the mobile power management system continuously detects the water outlet temperature Tin (TMS_ OutWaterTemp) sent by the water cooling system controller.

When Tin is more than or equal to 15 ℃, the mobile power management system requests the setting mode as follows: the cooling mode, i.e. "BMS request set mode" (bms_ TMSStModeReq) =1 (cooling mode).

When Tin is less than 15 ℃ and Tin is more than or equal to 10 ℃, namely Tin is more than or equal to 10 ℃ and less than 15 ℃, the mobile power management system requests the setting mode to continue the setting before setting. For example, when the previous mode of the water cooling system controller (TMS) is the shutdown mode or the self-circulation mode, the mobile power management system requests the water cooling system controller (TMS) to start the self-circulation (bms_ TMSStModeReq =3: self-circulation mode); when the previous mode of the water cooling system controller (TMS) is the cooling mode, the mobile power management system requests the water cooling system controller (TMS) to continue cooling.

When Tin is less than 10 ℃, the mobile power management system requests to set the mode as follows: the self-circulation mode, namely, the mobile power management system requests the water cooling system controller (TMS) to start self-circulation (bms_ TMSStModeReq =3: self-circulation mode).

When the highest temperature Tmax of the mobile power supply module is less than or equal to 36 ℃ or the mobile power supply management system enters a power-down state, the mobile power supply management system requests the water cooling system controller (TMS) to set the mode as standby (bms_ TMSStModeReq =0).

When the high-voltage contactor inside the water cooling system controller (TMS) is closed, the water cooling system controller (TMS) is in a non-refrigeration state, no under-voltage alarm exists, the SOC is more than 5%, and the water cooling system controller (TMS) has no secondary or tertiary faults, the mobile power management system requests the water cooling system controller (TMS) to start self-circulation and close self-circulation, namely, when the conditions are met, the mobile power management system can request the water cooling system controller (TMS) to start self-circulation and close self-circulation.

The starting conditions are as follows: the highest temperature and the lowest temperature Deltat of the mobile power supply module are more than or equal to 8 ℃.

The closing conditions are: the highest temperature and the lowest temperature Deltat of the mobile power supply module are 0 ℃ or the water cooling system controller (TMS) enters a refrigeration mode or the water cooling system controller (TMS) has secondary or tertiary faults.

When the charging signal is an alternating current charging signal, the mobile power management system detects the temperature of the mobile power module after entering an alternating current charging flow, the lowest temperature of the mobile power module is recorded as Tmin, and the highest temperature of the mobile power module is recorded as Tmax.

When Tmin < 3 ℃ and Tmax < 40 ℃, the mobile power management system enters a pure heating mode. The mobile power management system goes through the power-on process firstly, then controls the heating relay to be closed, and requests to heat the total current of 8.5A.

Continuously heating the mobile power supply module, and when Tmin is more than or equal to 3 ℃ or Tmax is more than or equal to 40 ℃, exiting the heating mode by the mobile power supply management system, and entering a pure charging mode.

When Tmin is more than or equal to 3 ℃ and Tmax is more than or equal to 40 ℃, the mobile power management system enters a charging mode with a refrigerating side.

When the mobile power management system enters a charging and refrigerating mode, the mobile power management system continuously monitors the fault level of the water cooling system controller, the fault level is divided into three levels, namely a first-level fault level, a second-level medium fault level and a third-level serious fault level, and when the fault level of the water cooling system controller is monitored to be the second-level or the third-level, the static mobile power management system requests the water cooling system controller to start a corresponding mode.

When tms_ TMSRLYSTATE =1 (closed state). The mobile power management system defaults to send the target temperature BMS_ TARGETTEMP of the mobile power module to the water cooling system controller to be 20 ℃, and simultaneously, the mobile power management system continuously detects the water outlet temperature Tin (TMS_ OutWaterTemp) sent by the water cooling system controller.

When Tin is more than or equal to 15 ℃, the mobile power management system requests the setting mode as follows: the cooling mode, i.e. "BMS request set mode" (bms_ TMSStModeReq) =1 (cooling mode).
