[0002] The principle of new energy vehicles is to use electric motors instead of electric motors for driving. Electric motors can efficiently generate torque over a fairly wide speed range. The power source provides electrical energy to the drive motor of the electric vehicle, and the motor converts the electrical energy of the power source into mechanical energy, which is then used to drive the wheels and working devices through a transmission device or directly.
[0003] Currently, low temperatures significantly affect the activity of the power supply, reducing its discharge capacity and consequently decreasing the vehicle's range. Utility Model Content

[0028] Please see Figures 1 to 4 The vehicle power monitoring device in this embodiment includes a monitoring component, a preheating component, and a temperature regulating component.
[0029] The monitoring component includes a control chip 11 and a temperature sensor 12 connected to each other. The temperature sensor 12 is used to monitor the temperature of the vehicle power supply 20 in real time. The temperature sensor 12 is installed in the housing of the vehicle power supply 20. The housing has a through slot for facilitating the wiring of the temperature sensor 12 and other equipment. The control chip 11 is used to control the preheating component and the temperature regulating component based on the data monitored by the temperature sensor 12, so as to heat the vehicle power supply 20 through the preheating component and the temperature regulating component.
[0030] In this embodiment, the monitoring component further includes a temporary power supply 13, which supplies power to the control chip 11, temperature sensor 12, and preheating component. The preheating component is connected to the temporary power supply 13 via an electrical switch 33. The temporary power supply 13, control chip 11, and temperature sensor 12 are connected to form a first circuit, and the temporary circuit, electrical switch 33, and preheating component are connected to form a second circuit. The first circuit is connected in parallel with the second circuit. The control chip 11 is connected to the electrical switch 33, and the control chip 11 controls the opening or closing of the electrical switch 33 based on the data monitored by the temperature sensor 12, thereby controlling the idle or working state of the preheating component. It should be noted that a protective resistor 14 is connected between the temporary power supply 13 and the control chip 11, and the protective resistor 14 is used to limit the current of the first circuit.
[0031] In this embodiment, the preheating component includes a heating resistance wire 31 and a thermal insulation layer 32. The heating resistance wire 31 is arranged around the vehicle power supply 20, and the middle part of the heating resistance wire 31 is spirally arranged along the outer side of the vehicle power supply 20. The two ends of the heating resistance wire 31 are respectively connected to the temporary power supply 13 and the electric switch 33 through corresponding wires. The thermal insulation layer 32 has a semi-enclosed structure and a U-shaped cross-section. The thermal insulation layer 32 and the outer side of the vehicle power supply 20 enclose a receiving space, and the heating resistance wire 31 is located in the receiving space. The arrangement of the thermal insulation layer 32 helps to reduce the escape of heat. It is understood that, in order to facilitate the passage of wires, a through hole for inserting wires is provided on the thermal insulation layer 32.
[0032] It should be noted that before the vehicle is started, when the temperature sensor 12 detects that the temperature is lower than the first temperature control threshold recorded in the control chip 11, the control chip 11 will control the power switch 33 to turn off, and the temporary power supply 13 will supply power to the heating resistor 31. The heating resistor 31 will convert electrical energy into heat energy to preheat the vehicle power supply 20.
[0033] In this embodiment, the temporary power supply 13 is connected to the vehicle power supply 20 through the protection circuit 21 so that the vehicle power supply 20 can charge the temporary power supply 13. The protection circuit 21 is used to prevent the temporary power supply 13 from being underpowered or overloaded. Both the temporary power supply 13 and the vehicle power supply 20 are connected to the battery management system on the vehicle for real-time monitoring and management.
[0034] In this embodiment, the temperature control component includes a temperature control water tank 41 and three water pipes. One end of each of the three water pipes is connected to an electric three-way valve 45, and the other end of each of the three water pipes is connected to the temperature control water tank 41. The electric three-way valve 45 is connected to the control chip 11. Any two water pipes can be connected to the temperature control water tank 41 to form a water circulation structure. Specifically, the three water pipes are a first water pipe 42, a second water pipe 43, and a third water pipe 44. The first water pipe 42 and the second water pipe 43 are connected to form a water circulation structure around the electric motor. The second water pipe 43 and the third water pipe 44 are connected to form a water circulation structure around the vehicle power supply 20. The first water pipe 42 and the second water pipe 43 are connected to form a water circulation structure around the vehicle power supply 20 and the electric motor.
[0035] In this embodiment, the temperature control component also includes a first water pump and a second water pump. The first water pipe 42 is connected to the temperature control water tank 41 through the first water pump, and the second water pipe 43 is connected to the temperature control water tank 41 through the second water pump. Both the first water pump and the second water pump are connected to the control chip 11. The control chip 11 is also used to control the operation of the electric three-way valve 45, the first water pump and the second water pump based on the data monitored by the temperature sensor 12.
[0036] It should be noted that in low-temperature environments and before the vehicle is started, the vehicle power supply 20 is preheated by the heating resistance wire 31. When the vehicle is started, the motor works, converting electrical energy into mechanical energy and generating heat. The control chip 11 controls the electric three-way valve 45 to connect the first water pipe 42 and the third water pipe 44, forming a water circulation structure around the vehicle power supply 20 and the motor. The control chip 11 controls the first water pump to work, and the first water pump box transports water from the temperature regulating water tank 41 around the water circulation structure of the vehicle power supply 20 and the motor. The heat generated by the motor is transferred to the vehicle power supply 20 through the water in the circulation structure to further heat and keep the vehicle power supply 20 warm.
[0037] It should be noted that in a high-temperature environment, when the temperature detected by the temperature sensor 12 is higher than the second temperature control threshold recorded in the control chip 11, the electric switch 33 is turned on, the heating resistor 31 does not work, the control chip 11 controls the electric three-way valve 45 to connect the second water pipe 43 and the third water pipe 44, and controls the second water pump to work, so as to deliver water to the water circulation structure surrounding the vehicle power supply 20, which is beneficial to cooling the surrounding environment of the vehicle power supply 20.
[0038] In addition, in other embodiments, the electric three-way valve 45 and the first water pump are also connected to the vehicle's control system. When the temperature sensor 12 used to monitor the motor detects that the motor is overheating, the control system controls the electric three-way valve 45 to connect the first water pipe 42 and the second water pipe 43, and controls the first water pump to work. The first water pump delivers water to the water circulation structure formed by the connection of the first water pipe 42 and the second water pipe 43 to perform water cooling operation on the motor.
[0039] In practical implementation, the temperature of the vehicle power supply 20 is monitored in real time by the temperature sensor 12. Based on the data monitored by the temperature sensor 12, the control chip 11 controls the preheating component and the temperature regulation component to adjust the temperature of the vehicle power supply 20. When the temperature sensor 12 detects that the temperature of the vehicle power supply 20 is low, the control chip 11 controls the preheating component to work to preheat the vehicle power supply 20 and improve its discharge capacity. When the vehicle starts, the motor generates heat, which is transferred to the water circulation structure to further heat and keep the vehicle power supply 20 warm, thereby improving the problem of reduced power discharge capacity and reduced vehicle range when the vehicle power supply 20 is in a low-temperature environment.
[0040] It should be noted that the above implementation process is only to illustrate the feasibility of this application, but it does not mean that the vehicle power monitoring device of this application has only the above-mentioned unique implementation process. On the contrary, as long as the vehicle power monitoring device of this application can be implemented, it can be included in the feasible implementation scheme of this application.
