[0034] Currently, jump starters are mainly used to provide emergency starting power for various devices, especially when the battery is depleted or malfunctioning. They can quickly provide starting current to ensure the device starts normally, hence their common use in field rescue. However, in related technologies, jump starters may malfunction or be damaged under excessively cold or hot conditions, severely impacting the user experience.

[0035] Based on this, the present invention provides a starting power supply. By creating a cavity in the temperature conductor to house the battery pack, the temperature of the batteries can be evened out, preventing individual batteries from overheating. Furthermore, by placing the battery pack against the inner wall of the cavity, the efficiency of temperature conduction can be effectively improved. Since the temperature of the battery pack is evened out through the temperature conductor, electronic semiconductors can be mounted on the outside of the temperature conductor. Whether the electronic semiconductors are used for cooling or heating, the battery pack can be cooled or heated through the temperature conductor. By placing a temperature measurement module on the surface of the battery pack, the temperature measurement module can accurately obtain the temperature of the battery pack. Subsequently, the control module can accurately control the operating state of the electronic semiconductors based on the temperature data obtained by the temperature measurement module, enabling the starting power supply to operate normally in extreme temperature regions and improving the user experience.

[0036] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0037] Reference Figure 1 , Figure 1 A partial schematic diagram of the starting power supply provided in an embodiment of this utility model.

[0038] It is understood that the power supply includes a housing, a battery pack 200, a temperature conductor 100, a temperature measurement module, a temperature control module, and a control module U1. The temperature conductor 100 is installed inside the housing and has a cavity for housing the battery pack 200. If there is a gap between the battery pack 200 and the cavity, the heat transfer efficiency between them will decrease. Therefore, the battery pack 200 can be brought into contact with the inner wall of the cavity to reduce the gap, thereby improving the heat transfer efficiency between the battery pack 200 and the temperature conductor 100. The temperature conductor 100 can balance the temperature of each battery in the battery pack 200. The temperature measurement module is located on the surface of the battery pack 200 and is in direct contact with it, allowing it to accurately obtain the temperature of the battery pack 200. The control module U1 can then accurately obtain the temperature data of the battery pack 200 through the temperature measurement module. The electronic semiconductor 300 can cool or heat according to different current flows. If the electronic semiconductor 300 is in direct contact with the battery, it may cause the battery pack 200 to overheat locally, thus damaging the battery. Therefore, the electronic semiconductor 300 can be installed on the side of the temperature conductor 100 away from the battery pack 200 and in contact with the temperature conductor 100, so that the battery pack 200 can be cooled or heated through the temperature conductor 100. The control module U1 is connected to the temperature measurement module, the electronic semiconductor 300, and the battery pack 200, so that the control module U1 can control the current flow of the electronic semiconductor 300 according to the temperature data obtained by the temperature measurement module. The electronic semiconductor 300 can cool or heat according to different current flows. For example, the forward conduction of the electronic semiconductor 300 is for heating, and the reverse conduction of the electronic semiconductor 300 is for cooling.

[0039] It should be noted that the battery pack 200 can be composed of a single battery. When the battery pack 200 has only one battery, the temperature conductor 100 has only one receiving cavity.

[0040] It should be noted that the battery pack 200 is composed of multiple batteries of the same shape and size. In some embodiments, the shape of the inner wall of the receiving cavity is the same as the shape of the side of the battery, wherein the side of the battery that abuts against the side wall of the receiving cavity is the side of the battery.

[0041] It should be noted that the battery pack 200 is composed of multiple batteries of the same shape and size, and the temperature conductor 100 has multiple receiving cavities, each containing at least one battery. For example, Figure 1 The battery pack 200 consists of four batteries. The temperature conductor 100 has four accommodating cavities, each containing one battery, to improve temperature transfer between the multiple batteries. Furthermore, as... Figure 2 As shown, Figure 2 This is a partial schematic diagram of a starting power supply provided in another embodiment of the present invention. The battery pack 200 consists of four batteries. The temperature conductor 100 has two receiving cavities, and each receiving cavity contains two batteries, wherein the two batteries in each receiving cavity are in contact with each other.

[0042] Reference Figure 3 and Figure 4 , Figure 3 This is a circuit diagram of the temperature control module provided in an embodiment of the present invention. Figure 4 A circuit diagram of the control module provided in an embodiment of this utility model.

[0043] Understandably, the temperature control module also includes transistor Q1, first diode D1, relay SW1, first resistor R1, second resistor R2, third resistor R3, first capacitor C1, second capacitor C2, third capacitor C3, fourth capacitor C4, and fifth capacitor C5. Relay SW1 includes a control terminal and a switching terminal. The control terminal includes a first connection point and a second connection point, and the switching terminal includes a third connection point, a fourth connection point, a fifth connection point, a sixth connection point, a seventh connection point, and an eighth connection point. The two ends of the first resistor R1 are connected to the temperature control terminal PTC-SW / EN of the control module U1 and the base of transistor Q1, respectively. The first end of the second resistor R2 is connected between the base of transistor Q1 and the first resistor R1, and the second end of the second resistor R2 is grounded. The collector of transistor Q1 is connected to the positive terminal of the first diode D1 and the control terminal, respectively. The first connection point and the first terminal of the first capacitor C1 are connected. The first terminal of the third resistor R3 is connected to the negative terminal of the first diode D1, the second connection point of the control terminal, and the second terminal of the first capacitor C1. The second terminal of the third resistor R3 is connected to the battery pack 200 and the eighth connection point of the switch terminal. The battery pack 200 is also connected to the third connection point of the switch terminal, the first terminal of the second capacitor C2, and the first terminal of the third capacitor C3. The second terminals of the second capacitor C2 and the second terminals of the third capacitor C3 are grounded. The fourth and seventh connection points of the switch terminal are grounded. The fifth connection point of the switch terminal is connected to the first terminal of the fourth capacitor C4, the first terminal of the fifth capacitor C5, and the first terminal of the electronic semiconductor 300. The sixth connection point of the switch terminal is connected to the second terminal of the fourth capacitor C4, the second terminal of the fifth capacitor C5, and the second terminal of the electronic semiconductor 300. Among them, the fourth capacitor C4 and the fifth capacitor C5 are filter capacitors.

[0044] It should be noted that in the initial state, transistor Q1 is in the off state, and the control terminal of relay SW1 is not energized. At this time, the fifth and seventh connection points of the switch terminal are connected, and the sixth and eighth connection points of the switch terminal are connected. If the battery pack 200 supplies power to the electronic semiconductor 300, the operating current provided by the battery pack 200 flows into the second terminal of the electronic semiconductor 300 through the eighth connection point of the switch terminal, and then flows from the first terminal of the electronic semiconductor 300 into the fifth connection point of the switch terminal, forming a current loop. If it is necessary to switch the operating state of the electronic semiconductor 300, the control module U1 can send a high-level signal to the base of transistor Q1 through the temperature control terminal PTC-SW / EN, thereby turning on transistor Q1 and activating the control terminal of relay SW1. At this time, the third and fifth connection points of the switch terminal are connected, and the fourth and sixth connection points of the switch terminal are connected. The operating current provided by the battery pack 200 flows into the first terminal of the electronic semiconductor 300 through the third connection point of the switch terminal, and then flows from the second terminal of the electronic semiconductor 300 into the sixth connection point of the switch terminal, forming a current loop. By controlling the on / off state of the control terminal of relay SW1, the connection mode of the switch terminal is changed, thereby supplying forward or reverse power to the electronic semiconductor 300, achieving the switching between heating and cooling. For example, when the fifth and seventh connection points of the switch terminal are connected and the sixth and eighth connection points are connected, the electronic semiconductor 300 is in heating mode; when the third and fifth connection points of the switch terminal are connected and the fourth and sixth connection points are connected, the electronic semiconductor 300 is in cooling mode. The electronic semiconductor 300 is a PTC semiconductor with both heating and cooling functions.

[0045] It should be noted that the connection port between the battery pack 200 and the temperature control module is P+.

[0046] It should be noted that the power supply also includes a protection module, which includes a second electrostatic discharge (ESD) protection device. One end of the second ESD protection device is connected to the first protection terminal KEY1 of the control module U1, and the other end is grounded. By setting up the second ESD protection device, the control module U1 can be protected from damage caused by electrostatic discharge.

[0047] It should be noted that the protection module also includes a third electrostatic discharge (ESD) protection device. One end of the third ESD protection device is connected to the second protection terminal KEY2 of the control module U1, and the other end is grounded. By setting the second and third ESD protection devices, the control module U1 can be protected from damage caused by electrostatic discharge.

[0048] It should be noted that the power supply also includes an LED module, which comprises LED diodes connected to the indicator terminal of the control module U1. The control module U1 can control the LED diodes to display different colors according to the operating state of the electronic semiconductor 300. The indicator terminal of the control module U1 is either the LED1 port or the LED2 port. For example, when the electronic semiconductor 300 is in heating mode, the LED diodes light up red; when the electronic semiconductor 300 is in cooling mode, the LED diodes light up green. The housing can have mounting holes for the LED diodes, allowing the user to visually understand the operating status of the electronic semiconductor 300.

[0049] Reference Figure 5 , Figure 5 A circuit diagram of the temperature measurement module provided in an embodiment of this utility model.

[0050] Understandably, the temperature measurement module includes a thermistor NTC1, a fourth resistor R4, and a sixth capacitor C6. The first end of the fourth resistor R4 is connected to the power supply terminal NTC-VDD of the control module U1, and the second end of the fourth resistor R4 is connected to the first end of the thermistor NTC1. The second end of the thermistor NTC1 is connected to the ground terminal NTC-GND of the control module U1. The connection point between the thermistor NTC1 and the fourth resistor R4 is the first terminal. The detection terminal NTC_AD of the control module U1 is connected to the first terminal. The first end of the sixth capacitor C6 is connected between the detection terminal NTC_AD of the control module U1 and the first terminal, and the second end of the sixth capacitor C6 is grounded. Since the thermistor NTC1 is connected to the ground terminal NTC-GND of the control module U1, it forms an independent ground terminal that is not affected by external power supply ripple. Therefore, the detection terminal NTC_AD of the control module U1 can perform voltage correction by combining the power supply terminal NTC-VDD and the ground terminal NTC-GND of the control module U1, thereby improving the accuracy of the detection terminal NTC_AD of the control module U1 and thus improving the accuracy of the control module U1 in acquiring temperature data.

[0051] It should be noted that the thermistor NTC1 can be a thermistor with a negative temperature coefficient.

[0052] It should be noted that the thermistor NTC1 is disposed on the surface of the battery pack 200. For example, the battery pack 200 consists of four batteries, namely a first battery, a second battery, a third battery, and a fourth battery, and the thermistor NTC1 can be disposed on the surface of the second battery or the third battery. Furthermore, in some embodiments, the temperature measurement module is divided into a first temperature measurement module and a second temperature measurement module, i.e., it has a first thermistor and a second thermistor. The first thermistor can be disposed on the surface of the second battery, and the second thermistor can be disposed on the surface of the third battery.

The second terminal of resistor R5 is connected to the input terminal of step-down chip U2. The first terminal of the first electrostatic discharge (ESD) protection device ESD1 is connected between the fifth resistor R5 and the input terminal of step-down chip U2. The second terminal of the first ESD protection device ESD1 is grounded. The first terminal of the seventh capacitor C7 is connected between the fifth resistor R5 and the input terminal of step-down chip U2. The first terminal of the eighth capacitor C8 is connected to the output terminal of step-down chip U2. The output terminal of step-down chip U2 is also connected to the power input terminal VDD of control module U1.
