Make a switch

CJ Lang and Son is part of the Spar network and runs a 180,000 sq ft multi-temperature distribution centre in Dundee. A busy operation, delivering between 300,000 and 400,000 cases per week across different temperature regimes requires a logistics operation of 3 shifts per day over 24 hours, 6 days a week. 

This makes the need for their fleet of 40 reach trucks, counter balance, assembly trucks, loading trucks and powered pallet trucks from Toyota to be readily available at all times. Some of the MHE also used secondary batteries to keep the vehicle running during the shift operations.

Having recently replaced their whole fleet of manual handling equipment to more modern equipment and technology, they found that their existing battery charging infrastructure, a mixture of older 50 Hz and High Frequency (HF) technology, was inadequate and inefficient for their latest MHE fleet. 

Distribution director Colin Chapman began his search for a new battery charging solution. “I liked how Fronius’ charging concept aligned to our MHE replacement strategy and CSR programme. We set up a trial and data capture unit in early 2020 and the results proved the concept.”

Selectiva 4.0 battery chargers were installed as a trial at the Dundee distribution centre. Its Ri charging process adapts individually to the condition of each battery, its state of charge and age of the batteries. This ensures a cooler, gentler and more energy efficient charge.

In order to cope with the different temperature zones, the “temperature controlled charging” option was installed. With this option, the charging voltage is adapted according to the temperature of the battery therefore providing sustainable protection and increasing the battery’s service life.

Having installed 37 Selectiva 4.0 battery chargers, CJ Lang expect to reduce its CO2 emissions by 265,000 kg and reduce energy costs and associated battery top up costs by around £100,000 in the next five years.
