When it comes to Li-Ion batteries, you don’t want to mess around. On top of that my design incorporated a PTC fuse, and on top of that I had a current sensing circuit monitored by the microcontroller that controlled the board. This battery pack had its own overvoltage, undervoltage, and overcurrent protection circuitry.

I recently developed a product that used three 18650 cells.

If you came here from an internet search because your battery just blew up and you don’t know how to put out the fire, then use a regular fire extinguisher if it’s plugged in to an outlet, or a fire extinguisher or water if it is not plugged in. Posted in Arduino Hacks, Transportation Hacks Tagged arduino nano, battery management, battery monitor, marine, NRF24, TFT display Whether you’re tracking battery voltages or temperatures reported by your BLE thermometers, a centralized dashboard that can collect and visualize that data is a handy thing to have.

The software isn’t using the onboard NRF24 radio yet, though with code space quickly running out on the Arduino Nano, there’s some concern about getting it implemented.Īs we said the first time we covered this project, you don’t need to have a boat to learn a little something from the work has put into his monitoring system. There’s still a good chunk of screen real estate available, so he’s currently brainstorming other visualizations or functions to implement. With the help of a newer and faster TFT display library, he’s created a more modern user interface complete with a color coded rolling graph to show voltages changes over time. Under the hood he’s also made some notable software improvements. The printed enclosure also allowed for the addition of some niceties like an integrated 7805 voltage regulator to provide a solid 5 V to the electronics, as well as a loud piezo beeper that will alert him to problems even when he can’t see the screen. He’s now addressed those points with his 3D printer, and in the write-up provides a few tips on shipboard ergonomics when it comes to mounting a display you’ll need to see from different angles. Recent log entries on the project’s Hackaday.io page detail some of the changes made since the last time we checked in, and describe the successful first test of the system on the water.Ĭertainly the biggest issue that was preventing from actually using the monitor previously was the lack of an enclosure and mounting system for it. In this case, only recently put the necessary finishing touches on his monitor and got it installed on the boat.

Sometimes a project unexpectedly goes from having your full attention to winning an all-expense-paid trip to the back burner. While it was still a work in progress, it seemed things were progressing along quickly.īut we know how it is. With dedicated batteries for starting the engines, cranking over the generator, and providing power to lights and other amenities, the device had to keep tabs on several banks of cells to make sure no onboard systems were dipping into the danger zone. A little over a a year ago, we covered an impressive battery monitor that was designing for his boat.
