Structure and handling of the trolley

3.2 Power supply modes

Two different power supply modes are available for running the detection system:
a) Operating via batteries/accumulators
b) Operating via mains

3.2.1 Operating via battery

For operating the trolley via battery/accumulator, a Lithium-ion based accumulator with 24 V DC and a minimum capacity of 100 Ah is required to operate the trolley for at least 6 hours.

The accumulator is located in an aluminum housing. The lid of the housing hosts an ODUMac connector which connects the battery with the electronics.

Batteries have been chosen and are provided by the user which are easily available on the local market. The trolley requires a supply voltage of 24 V DC. The batteries used for this trolley are from the company “energysource”. Two LEDs on top of the battery provide information on the charging and capacity status. Using light guides and a plastic interface for the LEDs on the battery, the corresponding status is visible from the outside of the housing via battery level indicator.

In case the battery has to be exchanged, three quick clamps can easily be opened to get access to it. The battery is firmly fixed in the housing by threaded bars and brackets. They can easily be opened. Batteries with maximum dimensions of 250 x 225 x 500 mm (H x W x D)
are suitable for the housing.
