The engine is known as the heart of the car. We all know that the operation of the engine requires oil to maintain lubrication, but there is also a particularly important liquid in the engine, which is antifreeze.With the continuous development of science and technology, new energy vehicles have become the future trend, and motors will replace engines in the future. It is worth noting that although a pure electric vehicle has only a motor, the high speed operation of the motor will inevitably generate a certain degree of high temperature due to the wear of the rotor bearing and the air. The battery is charged and discharged to generate heat and needs to be cooled. When the temperature is low, the battery needs to be heated to ensure Battery performance. In addition to the motor controller,DC/DCThe heat generated by the work also needs antifreeze cooling, so new energy vehicles are also inseparable from antifreeze.

Therefore, when we maintain the car on a daily basis, we mustTimely addition and timingReplacement, How to detect car antifreeze? Let me introduce the advantages and disadvantages of the two detection methods.

The simple control of liquid level control is to use the float level sensor, because this method is a simple and ancient detection method, and the price is relatively cheap. Its working principle is mainly to drive the float through the rise and fall of the water level. The magnet inside the float will also fall with the rise. In the process of rising and falling, the magnet will drive the reed switch to open and close, thus controlling the liquid level. It is a mechanical detection. The detection accuracy is easily affected by buoyancy, the repetition accuracy is poor, and different liquids need to be recalibrated. It is not suitable for viscous or impurity-containing liquid, which is easy to cause the floating ball to be blocked. Therefore, it is known that the float type liquid level sensor is easily affected by the water level and other factors, its accuracy is low, and the reliability is also low. After using for a period of time, it is easy to cause the phenomenon of floating ball stuck. In addition, the float type has the disadvantages of large volume, large installation space, complex installation process, loose structure and difficult cleaning. It is not very suitable for the detection of automobile freezing liquid.

The photoelectric liquid level sensor is based on the reflection of light in the two media to determine whether there is liquid or no liquid at this position. The two media are air and liquid. When the sensor head is exposed to the air, it belongs to the anhydrous state, and the light is directly reflected back to the receiver of the sensor; when the liquid is immersed in the sensor head, it belongs to the water state, and the light is refracted in the liquid, and only a small amount or no light is reflected back to the receiver. The sensor outputs different level signals according to these two states. According to the photoelectric liquid level characteristics, it is installed on a certain scale of the box body. If the antifreeze is too small, an alarm will be issued. Remind the owner of timely maintenance
