[0033]Belowfigure 1A cooling management system 100 of a vehicle-loaded stack 200 in accordance with an embodiment of the present invention is described.
[0034]According to an embodiment of the present invention, the cooling management system 100, including: a vehicle power source 1, a cooling water pump 2, a regulating circuit 4, and a controller 5. Specifically, the cooling water pump 2 has a coolant outlet 21 and a coolant inlet 22, a cooling conduit 3 is connected between the coolant outlet 21 and the coolant inlet 22, and the cooling conduit 3 is used to cool the car electric pile 200. The coolant is output by the cooling pipe 3, and the coolant is input, and the coolant is imported, thereby forming a complete cycle of cooling circuit, which in turn can realize the recyclable cooling system, and cool down the car electric pile 200, to ensure the car The cooling effect of the electric pile 200 is, and the vehicle-loaded 200 guarantees the optimal use performance by controlling the temperature control of the car electric pile 200.
[0035]Such asfigure 1As shown, the adjustment circuit 4 is connected between the vehicle power source 1 and the cooling water pump 2, and the vehicle power source 1 is powered by the adjustment circuit 4, and the adjustment circuit 4 is used to adjust the voltage of the cooling water pump 2.
[0036]Specifically, the vehicle-loaded vehicle inside the vehicle is used to generate heat, and the cooling cooling temperature of the vehicle carrier electric pile 200 is realized by using a liquid cooling inside the vehicle, and the cooling water pump 2 is transported, while the vehicle power supply 1 The output voltage and current value are fixed, so it is necessary to provide the adjustment circuit 4 between the cooling water pump 2 and the vehicle power source 1, and adjust the output voltage and current of the vehicle power source 1 to satisfy the output voltage and current to satisfy the cooling water pump 2. It is to be used, ie the output voltage and current of the vehicle power supply 1 cannot exceed the value of the cooling water pump 2, and cannot be lower than the numerical value required to operate in the cooling water pump 2, ensuring the stable operation of the cooling water pump 2 of the vehicle.
[0037]Further, the model of the cooling water pump 2 is different, and the voltage and current value required to operate are also different. According to the cooling management system 100 of the vehicle-loaded stack 200 according to the embodiment of the present invention, the cooling water pump 2 can be replaced, and there is no need to carry on the vehicle. The value of the power source 1 or the layout of the entire vehicle is substantially modified, and only the output voltage and current of the vehicle power source 1 can be adjusted according to the value of the replaced cooling water pump 2 by adjusting the circuit 4. Thereby, the replacement of the cooling water pump 2 of the vehicle also improves the selection range of the cooling water pump 2 of the vehicle, and reduces the overall R & D cost, there is no need to modify the overall layout or device inside the vehicle, reduce the internal modification of the vehicle. cost.
[0038]Further, such asfigure 1As shown, the controller 5 is connected to the adjustment circuit 4, and the controller 5 is used to control the interworking between the vehicle power source 1 and the cooling water pump 2. From this, it is understood that by controller 5 can control the power supply and power off of the cooling water pump 2 to achieve the control of the cooling function of the vehicle-loaded pile 200, the automation of the vehicle is realized, and the degree of automation of the vehicle is improved.
[0039]According to an embodiment of the present invention, the voltage and current output by adjusting the vehicle power source 1 to the cooling water pump 2 by adjusting the circuit 4 by adjusting the circuit 4 to the cooling water pump 2. To ensure the stable operation of the cooling water pump 2. Further, by adjusting the circuit 4, the output voltage and current of the vehicle power source 1 can be adjusted to a variety of types of cooling water pumps 2, even if the cooling water pump 2 of different models can be replaced, the cooling water pump 2 can be stabilized between the cooling water pump 2 and the vehicle power supply 1. In cooperation, there is no need to replace the structural device inside the vehicle's vehicle power source 1 or the interior of the vehicle, and the overall applicability of the cooling management system 100 of the vehicle-loaded pile 200 is lowered, and the overall modification cost of the internal structure of the vehicle-replacing the vehicle is replaced. Further, it also reduces the company's research and development costs.
[0040]Such asfigure 1As shown, the adjustment circuit 4 includes a drive transistor 41, a first adjustment element 42, a second adjusting element 43, and the first adjustment element 42 are connected in series between the driving transistor 41 and the controller 5, and the source and vehicle load of the transistor 41 are driven. The power supply 1 is coupled, the drain of the drive transistor 41 is coupled to the second adjustment element 43, and the cooling water pump 2 is connected to the drain of the driving transistor 41.
[0041]Specifically, between the controller 5 and the driving transistor 41, the adjustment controller 5 can be implemented to the current and voltage of the drive transistor 41 by connecting the first adjustment element 42. The source of the drive transistor 41 is coupled between the vehicle power source 1, and the drain of the driving transistor 41 is coupled to the second adjusting element 43, and the cooling water pump 2 is connected to the drain of the driving transistor 41, it can make the second adjustment The line of the element 43 is in parallel with the line of the cooling water pump 2, whereby the circuit in which the second adjusting element 43 is located can be shared by the circuit of the cooling water pump 2, so that the vehicle power supply 1 can be delivered to the cooling The electrical energy of the water pump 2 passes through the driving transistor 41 and the second adjustment element 43, thereby realizing the control of the output voltage and current of the vehicle power source 1, adapting the output power and the voltage of the vehicle power source 1 and the cooling water pump 2 to ensure the cooling water pump 2 Stable operation.
[0042]Further, such asfigure 1As shown, both the first adjustment element 42, and the second adjustment element 43 are adjustable resistors. That is, the first adjustment element 42 and the second adjusting element 43 may be a tonable resistor, i.e., by adjusting the resistance value of the adjustable resistor, to the cooling water pump 2 for the vehicle power supply 1 by adjusting the resistance value of the adjustable resistor. The voltage and current intensity so that the voltage and current supplied to the cooling water pump 2 meet its standard.
[0043]Alternatively, the resistance value of the adjustable resistor can be adjusted by manually adjusting, and may be adjusted by the controller 5 to perform adjustment of the resistance value of the adjustable resistor of the first adjustment element 42 and the second adjustment element 43, so that Convenient and fast adjustment is delivered to the current and voltage value of the cooling water pump 2. Further, after replacing the cooling water pump 2 of different models, quickly perform the current and voltage regulation of the use parameters of the new cooling water pump 2, convenient and fast.
[0044]Such asfigure 1As shown, the adjustment circuit 4 further includes: optically coupled 44, and the optical coupling 44 is connected in series between the controller 5 and the first adjustment element 42. The controller 5 can be effectively separated from the adjustment circuit 4 by optically parked 44, so that the feedback current can be effectively prevented from being too larger-cutting the controller 5, resulting in damage to the controller 5.
[0045]Specifically, when the feedback current is too large, the drive transistor 41 can be damaged. When the drive transistor 41 is damaged, the input current to the controller 5 may be present. The voltage received by the controller 5 needs to be less than or equal to 5V, and the input current requires less than or equal to 4 mA. If the current or voltage received by the controller 5 exceeds the rated voltage or current value, the controller 5 will be broken down. In order to better protect the controller 5, it is necessary to add light coupling 44 between the controller 5 and the first adjustment element 42, thereby acting as a protection controller 5.
[0046]Such asfigure 1As shown, the cooling management system 100 of the in-vehicle electric stack 200 of the present invention further includes a feedback circuit 6, and the feedback circuit 6 is connected between the controller 5 and the cooling water pump 2 to convey the operating parameters of the cooling water pump 2 to the control. The device 5. When the controller 5 is required to cool downward, the controller 5 operates, and the cooling water pump 2 is operated, and the coolant is transported to the cooling conduit 3, and the cooling cooling of the vehicle-loaded electric stack 200 is realized. When the cooling water pump 2 operates, it can be sent to the controller 5 by the feedback circuit 6 to facilitate feedback to the condition of the vehicle-loaded pile 200 to facilitate the real-time control of the cooling water pump 2.
[0047]Specifically, the cooling water pump 2 operates, and the coolant is transported into the cooling conduit 3, and the cooling conduit 3 performs cooling heat dissipation on the vehicle electric pile 200, and the state parameters of its own operation are passed through the feedback circuit 6 during the cooling water pump 2. Feedback to the controller 5, thereby controlling the operation of the cooling water pump 2 by the controller 5.
[0048]For example, when the cooling water pump 2 is stably operated, cooling and cooling is performed on the vehicle carrier 200, and when the temperature of the vehicle carrier 200 is lowered, the cooling water pump 2 feeds back the operating state parameters to the controller 5, and the controller 5 can control the cooling water pump. 2 The speed of the coolant is reduced to reduce the power consumption of the cooling water pump 2.
[0049]For example again, when the temperature of the vehicle carrier 200 is reduced to a certain value, the controller 5 can control the cooling water pump 2 after operating for 1 minute, after cooling the vehicle-loaded pile 200, stop running for 1 minute, then runs 1 minute to the vehicle-loaded vehicle 200 is cooling, then stop running for 1 minute, so reciprocated, it can guarantee cooling cooling to the car electric pile 200, and can effectively reduce the power consumption of the cooling water pump 2, save energy.
[0050]Such asfigure 1As shown, the feedback circuit 6 includes a first signal line 61, a second signal line 62, a first resistor 63, and a second resistor 64; wherein one end of the first signal line 61 is grounded, the other end of the first signal line 61 is connected. The cooling water pump 2, the first resistor 63 and the second resistor 64 are connected in series, and one end of the second signal line 62 is connected to the first signal line 61 between the first resistor 63 and the second resistor 64. The other end of the second signal line 62 is connected to the controller 5.
[0051]Specifically, one end of the first signal line 61 is connected to the cooling water pump 2, and the other end of the first signal line 61 processes the end portion after sequentially connecting the first resistor 63 and the second resistor 64, and the first resistance is connected in series The position between the 63 and the second resistor 64 is connected to the controller 5 through the second line, thereby forming a closed circuit.
[0052]By providing the first resistor 63 and the second resistor 64 in the feedback circuit 6, the output voltage and current of the cooling water pump 2 can be lowered when the cooling water pump 2 feeds back itself to the controller 5, and the output voltage and current of the output voltage and the current can be lowered. The parameters of the controller 5 are satisfied, preventing the voltage or current excessive pressure on the controller 5, resulting in damage to the controller 5.
[0053]Such asfigure 1As shown, the cooling management system 100 of the in-vehicle electric stack 200 of the present invention further includes a temperature detecting member 7, a temperature detecting member 7 for detecting the temperature of the vehicle carrier 200, and the temperature detecting member 7 is used to feed back the test results. Controller 5.
[0054]The temperature of the vehicle carrier 200 can be observed by the temperature detecting member 7, and the operating state of the vehicle carrier electric pile 200 can be observed, and the controller 5 can control the cooling water pump 2 by filling the temperature data of the vehicle-loaded electric stack 200 of the controller 5. Opening, after the temperature of the vehicle carrier 200 exceeds a certain value, the temperature of the car electric stack 200 is cooling.
[0055]Such asfigure 1As shown, the temperature detecting member 7 is connected to the cooling water pump 2, and the cooling water pump 2 transmits the detection result to the controller 5 through the CAN data line 8. The temperature detecting member 7 is connected between the cooling water pump 2, and after the temperature detection of the vehicle carrier 200, the temperature parameter information of the vehicle-loaded stack 200 is transmitted to the cooling water pump 2, and the cooling water pump 2 will carry the vehicle electric pile 200. The temperature information is fed back to the controller 5 via the CAN data line 8, and can also be controlled by the controller 5 to control the cooling and cooling treatment of the vehicle electric stack 200.
[0056]Further, the temperature detecting member 7 is plural, and the plurality of temperature detecting members 7 are spaced on the vehicle-loaded stack 200. The temperature information of the plurality of positions of the vehicle carrier electric stack 200 can be detected by the temperature information of the vehicle carrier 200 to ensure the accuracy of the temperature detection information of the vehicle carrier power stack 200, and it can be easier to facilitate the controller 5. The control cooled water pump 2 cools cooling effect on the vehicle-loaded pile 200.
[0057]Belowfigure 1The overall operational flow of the cooling management system 100 of the vehicle-loaded power stack 200 described in the embodiment of the present invention will be described.
[0058]Such asfigure 1As shown, the controller 5 of the vehicle operates and can control the supply and stop of the in-vehicle power source 1 to the cooling water pump 2, and the controller 5 can control the operation and stop of the cooling water pump 2.
[0059]The optocoupler 44 can isolate between the controller 5 from the adjustment circuit 4 to prevent the circuit of the controller 5 due to the feedback current.
[0060]Further, the specification or other information of the cooling water pump 2 used by the vehicle can acquire the model number and various parameters of the cooling water pump 2, and can understand the voltage and current ranging range of the cooling water pump 2 stably operate.
[0061]By adjusting the first adjustment element 42 and the second adjusting element 43, the output voltage current of the in-vehicle power source 1 can satisfy the use requirement, in the cooling management system 100 of the vehicle-loaded stack 200 of the present invention, The first adjustment element 42 and the second adjustment element 43 use the adjustable resistance, that is, by adjusting the resistance value of the adjustable resistor, the output voltage and current size of the vehicle power source 1 on the cooling water pump 2 are realized, and the PWN output by the drive transistor 41 is output. The signal is satisfied with the voltage requirements of the cooling water pump 2, and it is necessary to satisfy the current requirements to ensure the stable operation of the cooling water pump 2.
[0062]It should be noted that in the cooling management system 100 of the vehicle-loaded stack 200 of the embodiment of the present invention, the drive transistor 41 can use a triode. Such asfigure 1It can be seen that the C pole of the triode is connected to the vehicle power supply 1, the B pole of the triode is connected to the first adjustment element 42, and the E pole of the triode is connected to the cooling water pump 2.
[0063]A plurality of temperature detecting members 7 can be provided around the vehicle-loaded pile 200, and the accuracy of the obtained temperature value can be guaranteed, during the vehicle operation, the cooling water pump 2 can acquire the temperature value of the vehicle-loaded electric pile 200 through the temperature detecting member 7, and Pass throughfigure 1The displayed CAN data line 8 transmits the temperature parameter information acquired by the temperature detecting member 7 to the controller 5.
[0064]When the temperature of the vehicle carrier pile 200 exceeds its stable operation, the temperature exceeds the set threshold, the controller 5 can transmit the PWM duty cycle signal, passed the signal to the cooling water pump 2 by the drive transistor 41, ie, as previous It is said that the PWN signal is output to the cooling water pump 2 by the E pole of the triode, so that the cooling water pump 2 is cooled to cool down.
[0065]At the same time, when the cooling water pump 2 is operated, it is fed back to the controller 5 by the feedback circuit 6, and the controller 5 can control the operation of the cooling water pump 2.
[0066]Specifically, such asfigure 1As shown, the cooling water pump 2 cools down the cooling temperature of the vehicle carrier 200, which is provided to the cooling pipe 3 in the vehicle-loaded pile 200, and the two ends of the cooling conduit 3 respectively with the cooling water pump 2, respectively, the coolant outlet 21 and the coolant The inlet 22 is connected, thereby forming a circuit between the cooling water pump 2 and the cooling conduit 3 to circulate the coolant circulation, and achieve cooling of the vehicle-loaded stack 200.
[0067]According to an embodiment of the embodiment of the present invention, a cooling management system 100 and a vehicle-mounted heat stack 200 of the vehicle-loaded power stack 200, and the cooling pipe 3 of the cooling management system are provided on the vehicle power stack 200. Such asfigure 1As shown, the cooling pipe 3 of the cooling management system can be wound on the vehicle-loaded stack 200, so that the conveying coolant of the cooling water pump 2 is output to the cooling pipe 3 through the coolant outlet 21, and achieve cooling cooling of the vehicle electric pile 200.
