A battery powered industrial truck includes means to determine and/or display at least two parameters indicative of the energy available in the battery. The parameters may be determined from measurement of the time profile of the battery voltage. They may be a measure of the charge which can be removed from the battery under ideal discharge conditions i.e. the open terminal or state of charge voltage, Vsoc and the charge which can be removed when the vehicle is in operation (under load) i.e. battery condition voltage VCON. Both parameters may be indicated to the vehicle driver on an illuminated segment bar chart display 1. |
