Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of new energy vehicle battery temperature sensors, and more specifically to a new energy vehicle battery temperature sensor and a use method thereof. Background Art
[0002] The temperature sensor is one of the commonly used sensing devices for the internal temperature of new energy vehicle batteries. The common temperature sensor mainly consists of a power transmission device, a connecting wire group, a sensing mechanism, a power supply device, and a control system. The specific process of the temperature sensor monitoring the internal temperature of the new energy vehicle battery is as follows: the sensing mechanism is connected to the power supply device and the control system through the power transmission device and the connecting wire group so that it can perform temperature monitoring operations normally; The sensing mechanism mainly monitors the internal temperature through the internal thermal resistor, and the working principle of the monitoring is: the thermistor is made of semiconductor materials, most of which have a negative temperature coefficient, that is, the resistance decreases as the temperature increases. Therefore, the specific value of the internal temperature of the new energy vehicle battery can be determined by the change in resistance; At the same time, the small size of thermistors is an advantage. They can stabilize quickly and will not cause heat load. However, they are also very fragile, and large currents will cause self-heating. Since thermistors are resistive devices, any current source will cause heat on them due to power. Power is equal to the product of the square of the current and the resistance; therefore, a small current source should be used. If the thermistor is exposed to high heat, it will cause permanent damage. In the existing technology, the thermistor is fixed inside the new energy vehicle battery. Therefore, when the internal temperature of the new energy vehicle battery is at a continuous high temperature, it will cause certain damage to the sensing mechanism, which will lead to certain economic losses. Therefore, the market is in urgent need of a temperature sensor that can protect itself according to high temperature changes. Summary of the invention

9. The method for using a new energy vehicle battery temperature sensor according to claim 1, characterized in that: The steps include: Step 1: During operation, the connection line group (102) is connected to the interior of the new energy vehicle to facilitate power supply to the temperature sensor (103) and transmission of temperature data L monitored by the temperature sensor (103), and the temperature data L is transmitted to the interior of the monitoring system (4) for real-time monitoring; Step 2: During operation, the lifting mechanism (3) controls the temperature sensor (103) to move to the inside of the new energy vehicle battery. During the movement, the temperature sensor (103) is pressed against the limit bracket (203) and the limit rubber pad (204), driving them to rotate. At the same time, when the temperature sensor (103) moves to a specified position inside the new energy vehicle battery, the limit bracket (203) drives the limit rubber pad (204) to be pressed against the surface of the temperature sensor (103) under the drive of the second torsion spring column, thereby achieving the function of limiting and fixing the temperature sensor (103). After the temperature sensor (103) reaches the designated position, the refueling sealing plate (202) drives it to be in an open state, so as to facilitate monitoring of the internal temperature of the new energy vehicle battery. When the internal temperature of the new energy vehicle battery is in a continuously high temperature state, the monitoring system (4) drives the temperature sensor (103) to move to the top of the housing (201), and at the same time, the sealing plate (202) is driven by the first torsion spring column (205) to return to the original position, thereby driving the sealing plate (202) and the housing (201) to form a partition structure, thereby achieving the function of protecting the temperature sensor (103); Step 3: The monitoring system (4) controls the electric hydraulic column (302) to input a corresponding current so as to drive the protective shell (304), the limit plate (308), the card slot compartment (309) and the temperature sensor (103) to move up and down. When the internal temperature of the new energy vehicle battery needs to be monitored, the electric hydraulic column (302) controls the protective shell (304), the limit plate (308), the card slot compartment (309) and the temperature sensor (103) to move to the inside of the new energy vehicle battery to collect temperature data L. When the monitoring system (4) detects that the internal temperature data L of the new energy vehicle battery exceeds the normal temperature data within 10-30 minutes, the electric hydraulic column (302) controls the protective shell (304), the limit plate (308), the card slot compartment (309) and the temperature sensor (103) to move to the top of the housing (201) so as to achieve the effect of protecting the temperature sensor (103) in real time.
