NTC thermistors are often used in temperature detection, temperature control, temperature protection and other applications.
In summary, NTC is an important thermistor, whose resistance value decreases with the increase of temperature, and is widely used in the field of temperature detection and control.
NTC thermistors are widely used in various electrical equipment and electronic products. Its main functions include temperature detection, temperature control and current limit. For example, in electronic equipment, NTC can be used to monitor the temperature inside the device to prevent damage due to overheating; In battery applications, it can play a role in preventing overheating and protecting the safety of the battery when charging.
NTC thermistors are widely used in a variety of electronic devices, especially in cases where temperature needs to be measured and controlled. For example, they are commonly used in battery protection, temperature measurement, and control systems. Because of its ability to fineThe ability to sense temperature and respond quickly has become an integral part of modern electronics. Technical features: Compared with traditional temperature measurement methods, NTC thermistors have higher accuracy and response speed.
Application of thermistors in the automotive industry: The automotive industry is now replacing the space industry as the driver of sensor technology advances. Thermistors are widely used to test the temperature of air conditioners, engines, and water tanks in automobiles, and now there are many new applications. High requirements are now put forward for the thermistor industry: smaller size, higher stability, better high-temperature test performance, and so on. inProtection, temperature protection, short circuit protection, foreign body protection, overshoot protection, magnetic field protection and other functions. In particular, the temperature protection design, because the magnetic field produces heat after the temperature, when the magnetic field is constantly generated when charging, the temperature will be higher and higher, so the temperature protection is installed in the NTC thermistor to monitor and protect the wireless charging, it is to monitor the temperature around the coil.
2, buried in the charging circuit and the battery next to the temperature detection of the temperature NTC thermistor, and MCU together, you can track the instantaneous temperature change of wireless charging work.
3, wireless fast charging is byIC monitoring measures the voltage of the charging system, while NTC (negative temperature coefficient thermistor) is responsible for detecting the internal temperature of the system, preventing excessive temperature from causing excessive heat inside the wireless charger system to burn components and other safety problems, and can control components in the case of excessive temperature to reduce power, so as to achieve the effect of reducing temperature.
4, as far as possible to improve your wireless charging conversion efficiency optimize the control algorithm to enhance your heat dissipation effect plus heat sink or air cooling. The general wireless charging scheme will have a temperature control circuit and NTC thermistor, this function is mainly to prevent the circuit from workingThe heat generated in the process is too high, burning components and so on.
5, for high-power wireless charging roads such as new energy buses and new energy load trucks, whether they use constant current or constant voltage charging, due to high charging voltage and large charging flow, a constant power type NTC thermistor can be set at the input voltage entrance of the transmitter. To prevent or weaken the harmful impact of surge current on four MOS tubes, increase the life of MOS tubes and reduce the failure rate during charging.
6, the general wireless charging scheme will have a temperature control circuit and NTC thermistor, whichThis function is mainly to prevent the circuit from generating too much heat in the process of working, burning components, etc., and can also control the power components after generating too much heat, reduce the power, thereby reducing the temperature, this function is very important. Therefore, the wireless charging of the qi standard is originally the use of electromagnetic induction to generate current and promote the circuit to work.
Improve your wireless charging conversion efficiency as much as possible, optimize the control algorithm, enhance your heat dissipation effect, add heat sink or air cooling. General wireless charging scheme will come withTemperature control circuit and NTC thermistor, this function is mainly to prevent the heat generated by the circuit in the process of working too high, burn components and so on.
It is normal for the phone to heat up during wireless charging, but overheating can be dangerous. Wireless charging technology uses the principle of magnetic coupling to transfer power between the transmitter and the receiver. In this process, part of the electrical energy will be converted into heat, causing the phone and charger to heat up. This is a common phenomenon of wireless charging and does not mean there is a danger.
Wireless charging heating is a normal phenomenon, but there is a certain temperature range, generally in the descriptionIt will be noted in the book, and it is recommended to read the instructions carefully before use. There are a variety of standards for wireless charging, and you need to check which charging standard your phone supports before buying.
The secondary winding is broken, the wireless charging coil has two windings, one is the main winding, one is the secondary winding, after the secondary winding is damaged, it will cause the main winding to heat, and the output has no voltage.
Generally there is heat when charging the mobile phone at normal room temperature, the heat does not exceed 60℃ is a normal phenomenon, it will not damage the battery. The characteristic of wireless charging is that there is no limitation of charging cable, and there is a random one when chargingThe feeling of throwing, making people feel that picking up and putting back will hurt the battery very frequently, in fact, it is mainly affected by the nickel-metal hydride battery a long time ago.
