Abstract
The invention discloses an elevator driving method and a bidirectional dynamic solar elevator system. A photovoltaic battery used to provide power for an elevator. When the power supply is insufficient, a colloid storage battery is used to supplement the power. After discharging of the colloid storage battery reaches a maximum discharging depth, an elevator power supply system is switched to a power grid to provide the power. According to the invention, a solar driving elevator system can be fully used. The elevator can not stop operating because the power is off or the power is cut so that stability of the elevator can be increased.
