Advantages and drawbacks of each solution
| Solution | Pros | Cons |
| Centralized | - Less expensive than the modular solution
| - The temperature of 8 cell groups cannot be acquired.
- Lots of wires.
- 3 different boards to design.
- The consumption of the acquistion/balancing board is not easy to predict.
- In James' configuration, the acquisition/balancing board cannot work without the Rpi. Can be a safety issue in case of Rpi crash.
- Complicated Rpi monitoring/balancing programm in James's configuration.
|
Modular
| - Wires are reduced to the maximum.
- Works autonomously.
- Perfect galvanic isolation.
- Easier test, troubleshooting and maintenance.
- Easily scalable solution
- BMS own consumption is easy to manage
| - More hardware.
- A little more programming effort on the microcontroller side.
- Costs more than the centralized solution.
