In today’s fast-paced digital world, laptops have become indispensable tools. However, excessive charging can lead to overheating, which can significantly impact performance and battery life. In this blog post, we’ll explore a smart solution that leverages AWS services to automate laptop charging, prevent overheating, and optimize battery health. I do agree that Asus does provide premium support for a subscription, but this research and excercise was to brush up my brains and learn to create on aws with some useful solution. The solution is still in concept and once I start using it in production to the full extend, the shell scripts and cloudformation template will be pushed into github handle jthoma repository code-collection/aws
Understanding the Problem:
Overcharging can cause the battery to degrade faster and generate excessive heat. Traditional manual charging methods often lead to inconsistent charging patterns, potentially harming the battery’s lifespan.
The Solution: Automating Laptop Charging with AWS
To address this issue, we’ll utilize a combination of AWS services to create a robust and efficient automated charging system:
- AWS IoT Core: Purpose: This service enables secure and reliable bi-directional communication between devices and the cloud.
How it’s used: We’ll connect a smart power outlet to AWS IoT Core, allowing it to send real-time battery level data to the cloud.
Link: https://aws.amazon.com/iot-core/
Getting Started: Sign up for an AWS account and create an IoT Core project. - AWS Lambda: Purpose: This serverless computing service allows you to run code without provisioning or managing servers.
How it’s used: We’ll create a Lambda function triggered by IoT Core messages. This function will analyze the battery level and determine whether to charge or disconnect the power supply.
Link: https://aws.amazon.com/lambda/
Getting Started: Create a Lambda function and write the necessary code in your preferred language (e.g., Python, Node.js, Java). - Amazon DynamoDB: Purpose: This fully managed NoSQL database service offers fast and predictable performance with seamless scalability.
Link: https://aws.amazon.com/dynamodb/ - Amazon CloudWatch: Purpose: This monitoring and logging service helps you collect and analyze system and application performance metrics.
How it’s used: We’ll use CloudWatch to log system health and generate alarms based on battery level or temperature threshold. Also it helps to monitor the performance of our Lambda functions and IoT Core devices, ensuring optimal system health.
Link: https://aws.amazon.com/cloudwatch/
Getting Started: Configure CloudWatch to monitor your AWS resources and set up alarms for critical events.
How it Works:
- Data Collection: My Ubuntu system with the help of a shell script uses aws cli to send real-time battery level data to the cloud watch logs.
- Data Processing: Cloud watch metric filter alarms will trigger lambda function which is set for appropriate actions.
- Action Execution: The Lambda function sends commands to the smart power outlet to control the charging process.
- Data Storage: Historical battery level data is stored in Cloud Watch logs for analysis using Athena and further optimization.
- Monitoring and Alerting: CloudWatch monitors the system’s health and sends alerts if any issues arise.
Benefits of Automated Charging:
Optimized Battery Health: Prevents overcharging and undercharging, extending battery life.
Reduced Heat Generation: Minimizes thermal stress on the laptop.
Improved Performance: Ensures optimal battery performance, leading to better system responsiveness.
Energy Efficiency: Reduces energy consumption by avoiding unnecessary charging.
Conclusion
By leveraging AWS services, a sophisticated automated charging system that safeguards the laptop’s battery health and enhances its overall performance is reached. This solution empowers you to take control of your device’s charging habits and enjoy a longer-lasting, cooler, and more efficient laptop.
