Embodiment Construction

[0025] refer to figure 1 , shows a cleaning machine, in this case a sweeping machine 10 . The sweeping machine includes an enclosed cab 12 , a hopper 14 , suction nozzles 16 and brushes 18 . The sweeping machine includes a right front wheel 20 , a left front wheel 21 , a right rear wheel (not shown) and a left rear wheel 23 . The wheels support the chassis 13 . The front wheels are steerably mounted to the chassis, and the rear wheels are non-steerably mounted to the chassis.

[0026] The rear wheels can be driven by the electric motor 55 (located between the rear wheels ( figure 1 not shown, see figure 2 )) selectively driven in forward or reverse direction. The brushes can be selectively driven by another motor (not shown). A fan (not shown) for sucking dirt through such a suction nozzle 16 is driven by another electric motor (not shown).

[0027] Mounted on the left side of the vehicle is a first battery pack 30 having an upper compartment 31 and a lower compartment...

Abstract

The invention discloses a method for operating an electric vehicle, comprising the following steps: (1) providing the electric vehicle; (2) arranging an electric load device on the electric vehicle; (3) placing a first battery having a first state of charge (4) disposing a second battery pack having a second state of charge lower than the first state of charge on the electric vehicle; (5) determining an initial state of charge of the first battery pack; (6) determining the initial state of charge of the first battery; (7) connecting the first battery to an electrical load device; (8) measuring the current from the first battery; (9) calculating the instantaneous state of charge of the first battery; ( 10) comparing the instantaneous state of charge of the first battery with the initial state of charge of the second battery; and (11) when the instantaneous state of charge of the first battery reaches a predetermined percentage of the initial state of charge of the second battery, The second battery pack is connected in parallel with the first battery pack.

Description

technical field [0001] The present invention relates to a method for connecting two battery packs in parallel with a load, in particular two battery packs mounted on a vehicle and supplying electric power to propel the vehicle and perform other functions of the vehicle. [0002] In particular, the vehicle may be a cleaning machine. Background technique [0003] Cleaning machines, in particular road cleaning machines or road sweeping machines are well known. The terms "road cleaning" and "road sweeping" are used broadly to include the cleaning and sweeping of other areas such as pedestrian areas, sidewalks, parking lots, and the like. Road cleaning machines are machines used to get dirt off the road and into hoppers. A road sweeping machine is a road cleaning machine designed to brush dirt off the road, usually towards or into a hopper. In many road sweeping machines, a suction pipe (or hose) is provided along with a floor following nozzle for sucking up sweeping dirt from...
