Energy Storage and Recovery System for Lift

摘要

The elevator, from the grid side, is an impulsive load. Most of the energy used is lost during braking and/or deceleration phases. There are different ways to recover the loosen energy, but only one way is really convenient in terms of cost and efficiency: store and recovery the energy. An energy storage system requires having an accumulator that performs in an optimal way: high efficiency, bidirectional, long life, quick response time. The advantages of using an energy storage system for such application are: lower engaged power, higher efficiency due to recovery of breaking energy and energy continuity during blackout to finish the race.
