The battery performance may be reduced due to the excessively high or low battery temperature, and it is very important to closely monitor the battery temperature in order to maintain the battery performance, and the use of the thermistor for monitoring, controlling and compensating the temperature in the battery is suitable. The thermistor functioning as the temperature monitoring function is a Negative Temperature Coefficient (NTC) thermistor.
Generally, an adapter battery for supplying power to an electrical device has at least a positive terminal, a negative terminal, and a thermistor terminal, the positive terminal of the adapter battery and the negative terminal of the adapter battery are used for electrically connecting with the electrical device to supply power to the electrical device, and the thermistor terminal of the adapter battery is electrically connected with the thermistor of the adapter battery.
The electric equipment comprises an anode battery end, a cathode battery end and a thermistor end, wherein the anode battery end of the electric equipment is used for electrically connecting the anode end of the adaptive battery, and the cathode battery end of the electric equipment is used for electrically connecting the cathode end of the adaptive battery so as to receive the working voltage provided by the adaptive battery. The thermistor end of the electric equipment is connected with a pull-up resistor, and the thermistor end of the electric equipment is clamped at a high level. Under normal conditions, the thermistor end of the electric equipment is used for being electrically connected with the thermistor end of the adaptive battery so as to be connected with the thermistor of the adaptive battery, therefore, the temperature of the adaptive battery is monitored, and corresponding protection actions are executed according to the temperature of the adaptive battery obtained through monitoring. Specifically, under the condition that the thermistor end of the electric equipment is electrically connected with the thermistor of the adaptive battery, when the temperature of the adaptive battery changes, the resistance value of the thermistor of the adaptive battery also changes, so that the voltage of the thermistor is different, and the voltage of the thermistor end of the electric equipment is different. Therefore, the electric equipment can obtain the temperature of the adaptive battery at the moment through the voltage of the thermistor end of the electric equipment according to the characteristic of the thermistor of the adaptive battery. It should be noted that the size of the pull-up resistor at the thermistor end of the device to be tested can be determined according to the characteristics of the thermistor adapted to the battery, and the characteristics of the thermistor can be a resistance-temperature table of the thermistor, a temperature-resistance relation curve or any characteristics which can be used for indicating the relation between the resistance and the temperature of the thermistor. It should be noted that it is conventional in the art for the powered device to determine the temperature of the adapter battery based on a voltage signal at the thermistor terminal of the powered device.
In order to ensure the performance of the adaptive battery or the performance of the electric equipment, a research and development staff can set a protection function as required before the electric equipment leaves a factory, for example, under the condition that the temperature of the adaptive battery of the electric equipment is higher than 70 ℃, the electric equipment executes shutdown operation to avoid the temperature of the adaptive battery from continuously rising, and under the condition that the temperature of the adaptive battery of the electric equipment is lower than 30 ℃ below zero, the electric equipment refuses charging operation.
As shown in fig. 1, the present high and low temperature commissioning test system includes a device under test 110, an adapter battery 120 of the device under test, and an incubator 130. Specifically, the device under test 110 is an electric device that needs high and low temperature debugging, the positive battery terminal 112 of the device under test is electrically connected to the positive electrode of the adaptive battery 120, the negative battery terminal 114 of the device under test is electrically connected to the negative electrode of the adaptive battery 120, and the thermistor terminal 116 of the device under test is electrically connected to the thermistor 122 of the adaptive battery 120. The device to be tested 110 and the adaptive battery 120 are located inside the incubator 130, the stable temperature of the adaptive battery is the target test temperature by adjusting the set temperature of the incubator 130, and whether the corresponding protection action (such as shutdown action) is executed by the device to be tested 110 when the temperature of the adaptive battery 120 is the target test temperature is further verified, so that whether the device to be tested 110 is qualified is judged. However, since it takes a certain time for the adapter battery 120 to reach the target test temperature, the above-mentioned debugging test using the incubator 130 is inefficient. Further, when the temperature of the incubator 130 is set to the target test temperature, after the temperature of the incubator 130 is stabilized, there may be an error between the actual temperature of the adaptive battery and the target test temperature due to various reasons, so that the temperature of the adaptive battery 120 is not matched with the target test temperature, and the high and low temperature debugging test result is unreliable. Meanwhile, the incubator 130 has a high cost, which results in a high and low temperature debugging and testing cost.
