In the next years the utility companies will offer more and more electricity tariffs whose pricing is based on the market principle of supply and demand. These so-called dynamic tariffs take into account the overall energy balance: variable amounts of electricity produced from PV and wind energy compared to fluctuating electricity consumption.
The bCUBE receives the current exchange electricity prices as well as forward-looking electricity price forecasts for the next 48 hours.
Based on this information in combination with the forecast local energy consumption, the system determines optimal charging times where energy is actively drawn from the energy supplier and temporarily stored in the battery. The goal here is to charge the battery with purchased electricity when prices are low so that the energy required in the house can be drawn from the battery again later when prices are high.
