Interrupt Controller for DC charging pile microcontrollers: Guardian to ensure real-time response

In the complex control logic of DC charging piles, the interrupt controller of the microcontroller is the core component that ensures that the system can respond to critical events in real time. It is responsible for managing interruption requests from various parts of the charging pile and ensuring that these requests are handled in a timely and correct manner.

Main component

Concept:

The interrupt controller is a special module inside the microcontroller that receives, identifies, and prioritizes interrupt requests from different parts of the charging pile. These requests may come from external events, such as user input, changes in sensor readings, or internal events, such as timer overflow. The interrupt controller ensures that in the event of an emergency or important event, the microcontroller can pause the current task and turn to deal with these interruptions, thus ensuring the stable operation of the charging pile and user safety.

Function:

1. Real-time response: The interrupt controller allows the microcontroller to respond quickly to emergency situations, such as overload protection or user emergency shutdown requests, ensuring safe charging.

2. Event processing: It processes events from various sensors and user interfaces of charging piles, such as current and voltage anomalies, gun lock state changes, etc.

3. Priority management: The interrupt controller allocates different priorities according to the urgency of the event to ensure that the higher-priority event is processed first.

4. Interrupt nesting: Support the interrupt nesting function, that is, when processing an interrupt, if a higher priority interrupt request occurs, the processor can interrupt the processing of the current interrupt and turn to the processing of a higher priority interrupt.

Working Principle:

1. Interrupt request recognition: When a certain part of the charging pile needs the attention of the processor, it will send an interrupt request signal to the interrupt controller.

2. Priority determination: The interrupt controller determines which interrupt requests need to be processed immediately according to the preset priority rules.

3. Interrupt service routine Call: Once an interrupt request is identified as requiring immediate processing, the interrupt controller suspends the current task of the microcontroller and invokes the appropriate Interrupt service routine (ISR) to handle the event.

4. Return to the main program: After the execution of the interrupt service program is completed, the microcontroller will return to the interrupted task and continue the previous work.

Sum up

Through this working principle, the interrupt controller of the DC charging pile microcontroller ensures that the charging pile can operate stably and safely, and can respond quickly to various emergency situations. It is an indispensable part of the charging pile microcontroller, providing a solid foundation for the intelligence and automation of the charging pile.

DC CHARGING PIlE SERIES

DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
