SEM is an energy storage system for elevators, that allows to recover the kinetic energy of the cabin during the braking phase, and the potential energy during the descending phase, that can be used during acceleration and rising phases.
How does it work?
The system is composed by an electronic control part and an energy accumulator (flywheel).
SEM allows to control the energy flow between the elevator and the electricity grid, through the energy storage into the accumulator, improving the absorption and power conditions.
Through the energy storage and its collection for a future use, we get that the instantaneous power required by the elevator and its movements, is not entirely supplied by the grid, but partly comes from the accumulator.
Used power reduction (- 75%)
Energy consumption reduction ( – 45%)
Saving on your bill 43%
