An automatic battery charging apparatus for driverless transport vehicle is presented so as to enable disconnecting the charging source from the batteries when a certain pressure is reached in the interior of at least one battery. A pressure sensor provided inside the battery is set so that the contact of a relay opens when a certain interior pressure which is lower than the activating pressure for a safety valve provided on the battery. This prevents an excessive pressure build up in the battery interior caused, for example, by accidental over-charging, which would release damaging gases and corrosive vapors from the over-charged battery to the outside environment. |
