SmartVolt

SmartVolt (Battery Management System Competition)

EVENT INFO

• Team composition: Team of 2 - 4 members
• Mode: Online+Offline

• Objective: 

In the first phase(Online), teams must design a Battery Management System (BMS) to monitor, protect, and optimise a high-voltage battery pack in an electric vehicle. The BMS should ensure the safety and reliability of the battery while staying within specified voltage, current, and temperature limits. Teams must demonstrate the BMS's functionality through tests that show its ability to handle faults, balance cells, and provide real-time monitoring in a simulated or actual EV environment. In the second phase(offline), teams must create their designed system using given components. The list of those components will be emailed to the selected candidates. Note that the code required to run the system and an overall report should be submitted in the second phase.

• Parameters to be Measured and Displayed in real-time: 

1. State Of Charge (SOC) 
2. State Of Health (SOH) 
3. Individual Cell Voltage (if multiple cells) and Pack Voltage 
4. Charge and Discharge Current 
5. Cell Temperature 
6. Number of charge/discharge cycles completed 

• Required Features: 

1. Fault Detection: 

The BMS should be able to detect faults like high temperature, over-discharging, overcharging, excessive current discharge, cell voltage imbalance (if multiple cells) and alert using a buzzer or by blinking an LED. 

1. Master Disconnect: 

The BMS should have a Master Disconnect feature, which completely isolates the battery from the rest of the system when a fault is detected. It should trigger if there’s an overvoltage, undervoltage, overcurrent, or overheating. This helps prevent damage or dangerous situations like fires. The disconnect can be either mechanical or electronic. After activation, the system may need to be reset before reconnecting the battery. 

• Judging Criteria: 

1) Participants will be awarded points based on whether the system works and how accurate the readings are.

2) Functionality and Performance:  BMS should monitor voltage, current and temperature well. It should quickly respond to the issues like overvoltage,  undervoltage, overheating, or overcurrent. 

3) The program should be simple and well-commented. Use of libraries is encouraged.  

4) The report should be concise and well-documented. 

5) Extra points are to be given for multi-cell BMS. 

6) Extra points to be given for a dedicated GUI for display or a display unit. 

• Things to bring:  

1) A model made in software. 

2) A report on the design of the system.
