Because of the electrical mobility evolution, there are a lot of Li-ion battery packs worldwide that are most of the time not being used. They can however be used in powering 3 phase household appliances (Vehicle 2 Home) or return electricity to the grid (Vehicle 2 Grid) at peak hours. The reason why this system is not economically viable yet, is because the Li-ion battery pack's life cycle is significantly reduced when charged/discharged a lot with low power quality (high inrush current, ripple) electricity, provided by current inverters and DC/DC converters.
The TAPAS boards are perfect for our battery cycle life tests. We already gathered life-cycle data from other experiments so we could compare this to the performance of the TAPAS boards.
Our idea is to test the high power quality capabilities of the TAPAS inverter board whether the cycle life degradation in a Li-ion cell and a Li-ion battery pack from a variable DC solar power supply. We would need two TAPAS boards (battery functions both as a load and a source):
But we would not stop there. We would also combine the TAPAS board with an external relay and Wifi board (z.B. ESP8266). This would allow flexible switching between charging and discharging based on:
The team consists of myself and 3 fellow electrical engineering graduate students. We already developed a flexible switching unit hardware board (with overvoltage protection circuit and a MOSFET per relay, controlled by an MCU)
We have a time schedule of 1 month for this idea.
If wanted, we can provide more information as we would love to start working with the TAPAS boards.
this idea will get two TAPAS dev kits
