What is the use of the car power adapter
Control motor, protection motor, position detection
The main uses of automotive power adapters include motor control, motor protection and position detection.
Control motor : power adapter as a brushless DC motor controller, through the integrated power conversion circuit, microprocessor and signal processing unit, can accurately control the motor, real-time monitoring of motor status, to ensure dynamic safety, and solve the past monitoring and control problems .
Protection motor : The driver contains a power amplifier circuit to amplify the command of the controller and drive the motor to perform the task. At the same time, multiple protection mechanisms are built in, such as over current, over voltage and under voltage protection, to ensure that the motor works in a safe range .
Position detection : photoelectric encoder is a kind of high-precision sensor. Through photoelectric conversion technology, the rotating position of the motor is converted into a pulse signal, which provides real-time position information for the controller to ensure the stable and efficient operation of the power system .
In addition, the power adapter also has the following functions:
Versatility : Some high-end car chargers generally include 2 USB interfaces, which can charge two digital products .
safety : has overload protection, short circuit protection, high voltage input protection and high temperature protection and other multiple safety protection functions .
communication function : communicates with BMS through high-speed CAN network, determines whether the battery connection status is correct, obtains battery system parameters, and monitors the battery data in real time before and during charging .
