##**Project name**: Energy-Saved Smart Kettle
##**Team Members**(3): Yuen Sun, Boxiang Zhao, Naomi Peng
##**Problem**: Nowadays, people are living a fast-paced life and most of us love to drink a cup of coffee or tea but probably give up because it could be time-consuming. Why not having something that can save us time from boiling water? We are always trying to improve the efficiency of everything. We do not want to waste our time on useless things. For example, it takes a few minutes to wait for the kettle to be full and boil and it is annoying. In addition, people have different requirements for the temperature of the water and when the water is too hot, they need to wait for it to cool down and when the water is too cold they need to boil it again. We are thinking of designing a smart kettle that could help people to spend less time on these useless things.

##**Solution Overview**:
-First, the smart kettle would be able to load a specific amount of water so that it won’t cause overflow and fire. We will be using a sensor that could sense how much water left in the kettle. So that we can ensure that exactly the amount of water will be boiled as needed.

-Second, a temperature sensor would be used to measure the temperature of the water in the kettle and display it on an LCD screen. In addition, the remaining time for the water to reach the target temperature.

-Last, different from the traditional way to keep warm, which is maintaining the water at a specific temperature, say 40 °C, we are modifying the features that we will only reheat to water to 40 °C when the temperature drops to 30°C. This is a good way to save electricity.

##**Solution Component**:
-Weight sensor is to measure the water amount in the kettle.
-Temperature sensor is to measure the temperature of the water.
-Water pump is to load water into the kettle from a water tank.
-Arduino is used to control and process the signal received from sensors.

##**Criterion for Success**
-Be able to display the remaining time to reach the target temperature, the displayed time should be close to the real needed time.
-Be able to refill the water automatically.
-Be able to reheat the water back to the target temperature.

The goal of this project is to design a low cost BMS (Battery Management System) system that is flexible and modular. The BMS must ensure safe operation of lithium ion batteries by protecting the batteries from: Over temperature, overcharge, overdischarge, and overcurrent all at the cell level. Additionally, the should provide cell balancing to maintain overall pack capacity. Last a BMS should be track SOC(state of charge) and SOH (state of health) of the overall pack.

To meet these goals, we plan to integrate a MCU into each module that will handle measurements and report to the module below it. This allows for reconfiguration of battery’s, module replacements. Currently major companies that offer stackable BMSs don’t offer single cell modularity, require software adjustments and require sense wires to be ran back to the centralized IC. Our proposed solution will be able to remain in the same price range as other centralized solutions by utilizing mass produced general purpose microcontrollers and opto-isolators. This project carries a mix of hardware and software challenges. The software side will consist of communication protocol design, interrupt/sleep cycles, and power management. Hardware will consist of communication level shifting, MCU selection, battery voltage and current monitoring circuits, DC/DC converter all with low power draws and cost.
