Title:
AUTOMATIC CHARGING METHOD AND DEVICE OF AUTOMATED GUIDED VEHICLE
Document Type and Number:
WIPO Patent Application WO/2008/066052
Kind Code:
A1
Abstract:
Automatic charging method and device for an automated guided vehicle (AGV) which can
carry out automatic charging quickly while enhancing safety at charging. A
power supply unit (1) is provided with a power supplier/controller (6) for radiating
electromagnetic energy converted from AC power (4) when the AGV (2) arrives at
a charge waiting position, and stopping radiation of electromagnetic energy
upon receiving an automatic charge completion signal (5). The AGV (2) is provided
with a a charge controller (10) which converts electromagnetic energy received
from the power supplier/controller (6) through electromagnetic induction coupling
into DC power (8) that is then supplied to a parallel circuit of a battery (3) and
a capacitor (9), and which transmits the automatic charge completion signal
(5) to the power supplier/controller (6) by radio upon charge completion of the
capacitor (9). Automatic charging is completed when charging of the capacitor (9)
to be charged in a short time is completed thus quickly completing automatic charging
of the AGV involving positional restriction, but the battery (3) is charged from
the capacitor (9) afterwards. Since charging power is converted into electromagnetic
energy and supplied to the AGV (2) in noncontact, the live part is not exposed in
the power transmission line for charging, thus enhancing safety at charging.
