Elevator power system having plural storage apparatuses
First Claim
1. A power supplying system for an elevator having an elevator car capable of stopping at two vertically spaced locations, comprising:
- a first electric storage apparatus provided at each of said vertically spaced locations for storing thereinto electric power derived from a commercial power supply;
a charging apparatus for charging the electric power derived from the commercial power supply to each of the first electric storage apparatuses and for controlling a current when the electric power is charged into each of the first electric storage apparatuses;
a second electric storage apparatus mounted at the elevator car for storing thereinto electric power used to operate an appliance of the elevator car; and
a power supplying apparatus for supplying the electric power derived from one of the first electric storage apparatuses to the second electric storage apparatus when the elevator car is stopped at one of the vertically spaced locations corresponding to the one of the first electric storage apparatuses.
