A Guide to Repairing a Lithium Iron Phosphate Motorcycle Battery

Ā  Ā  Welcome to the Cell Doctor channel. In todayā€™s video, we will explore the process of repairing a lithium iron phosphate (LiFePO4) motorcycle battery that is currently non-functional. A friend of mine reported that this battery was short-circuited. Although it still shows some indication of life with two lines, the voltage measurement reads 9.7 volts. We need to determine if it can receive any power.

Ā  Initial Diagnosis

Ā Firstly, we checked the voltage, confirming it reads 9.7 volts. However, the battery does not draw any current, indicating an issue. To understand the problem, we need to open the battery and inspect its internal components. Typically, these batteries contain a Battery Management System (BMS), and the fault could either lie within the BMS or the cells themselves.

Ā  Opening the Battery

Ā Opening the battery was straightforward. Upon removing the lid, we observed the balancing leads. The board is marked SMT H04 S LED LDVD O, indicating that it includes an LED board and balancing wires. We measured the voltage on these wires to assess the condition of the cells. The cells are encapsulated in silicon, which makes access difficult. However, we attempted to charge the cells through the balancing leads to avoid complete disassembly.

Ā  Cell Voltage Inspection

Ā The voltage readings showed 3.3 volts for one cell and 0.2 volts for another, indicating that one of the cells is dead. Specifically, cell number two is non-functional, while the other cells seem to be in good condition. We attempted to charge the dead cell by setting the bench power supply to 3.6 volts and connecting the leads. Unfortunately, the cell did not draw any power, confirming it is indeed dead.

Ā  Deeper Investigation

Ā Given the dead cell, we needed to delve deeper. Carefully cutting the silicon around the cells, we ensured not to puncture the good cells to prevent any fire hazard. Once the silicon was sufficiently removed, we extracted the battery. With the cells exposed, we found that they are spot-welded together, complicating the repair process.

Ā  Identifying the Fault

Further inspection revealed that cell number two had disconnected from its neighboring cell, causing the battery to fail. This disconnection needed to be repaired by soldering the cells back together.

Ā  Repairing the Connection

Ā Soldering these types of cells can be tricky, but we managed to make a good connection on half of the tab. After ensuring the connection was secure, we reassembled the battery and isolated the terminals with Kapton tape. We then reconnected the LED board to check for voltage. The state of charge indicator showed full, indicating the repair was successful.

Ā  Final Testing

Ā We conducted a final series of tests to ensure the battery was functional. The voltage now read 13.3 volts, and the battery accepted a charge of 3 amps. Additionally, we performed a discharge test at 5 amps, which the battery handled without significant voltage drop. The ultimate test was placing the battery back in the motorcycle to confirm it starts the engine.

Ā  Conclusion

Ā This video tutorial demonstrated the process of repairing a lithium iron phosphate battery with a broken cell connection. These batteries, utilizing pouch cells, are common in high-current applications but are more challenging to repair than cylindrical cells. Nonetheless, the repair was successful.

Welcome to the Cell Doctor Channel: Mega CNC Software Update

Ā  Ā  Ā Hey everyone, welcome to a new video on the Cell Doctor Channel. Today, we’re diving into the latest updates for Mega CNC, the software I’ve developed for controlling the MegaCell Chargers. I’ve been working on some new features that many of you have requested, so let’s take a look at what’s changed since the last video.

Development and Deployment

Ā  Ā I’ve been replacing placeholders on the page with real data. The total sales displayed are from testing on my development machine, which is running on Windows. Although developing and submitting changes is easier on Windows, deployment works best on Ubuntu and the Raspberry Pi image. I’ll be updating this image in the coming days for those who need it.

Updating Procedure

Ā  Ā If you already have sales data in your database, I recommend following the update procedure described on the Git page. You need to log into your Raspberry Pi or Ubuntu machine via SSH. The default username and password for the Raspberry Pi image is MCCadmin and MCCisbest, respectively. You can change these if you wish. To update, navigate to Mega CNC, perform a git pull, and then sudo docker-compose down. Rebuild and make the necessary database migrations.

Database Changes

Ā  I’ve made several changes to the database:

  • A new entry called “database” now loads all cells by default.
  • You can filter cells based on the project you’re working on.
  • The database displays detailed information for each cell, including capacity, ESR, number of cycles, availability, and various temperature metrics during charging and discharging.

You can also manually add cells to the database, specifying details such as project, device type, voltage, capacity, ESR, and other parameters.

Battery Management

Ā  The main purpose of this software and the MegaCell Charger is to manage and utilize battery cells efficiently. Here’s a rundown of the new battery management features:

  1. Creating and Managing Batteries: You can create new batteries by specifying the series and parallel configuration. Once created, the software helps you manage these batteries efficiently.

  2. Scanning and Assigning Cells: Using a QR code scanner, you can easily scan and assign cells to a battery pack. The software automatically pulls the cell data from the database and optimally assigns cells to ensure a balanced pack.

  3. Balancing Cells: The software calculates the best combination of cells to create a balanced pack, minimizing the difference in capacity across strings of cells.

Advanced Features

Ā  For those familiar with building battery packs, the software offers advanced features like:

  • Swapping Cells: You can swap cells within a pack if needed. However, this feature is still under development, so it’s best to use it cautiously.
  • Detailed Data Display: The software provides detailed information about each cell, including graphs and temperature data.
  • Auto-Selection and Assignment: You can auto-select cells for a pack based on specific criteria, making the process quicker and more efficient.

Final Thoughts

Ā  Ā Thank you for following this project. If you have any questions or suggestions for new features, don’t hesitate to contact me. Check out the latest products and a detailed presentation page on our website for more information about the MegaCell Charger project.

Stay tuned for the next video, and happy battery building!

All the best, The Cell Doctor
