Problems solved by technology

However, the current power supply method for wheel-mounted smart sensors on motor vehicles generally uses external small-capacity batteries, such as 1.2V / cell, etc., and it is difficult to achieve continuous and stable power supply for vehicle-mounted smart sensors, and it is more important to disassemble and replace batteries regularly. The most important thing is that the decline in power supply directly affects the data accuracy and transmission of related sensors, which has become a bottleneck in the development of vehicle-mounted intelligent monitoring technology.
