To control the energy used by the
warehouse truck fleet at its newest
distribution centre at Magna Park,
Milton Keynes, retailer John Lewis
Partnership has implemented a
combination of PowerNet battery
and power management systems
from EnerSys Motive Power.

The installation automatically
manages battery allocation to ensure
balanced utilisation, minimises
energy consumption and prevents
battery systems from drawing too
much power when overall demand
in the warehouse is above
predetermined limits. This ensures
other services are not disrupted and
avoids the need for costly additional
electrical infrastructure to keep the
installation within budget.

As the system runs on a standard
PC and is completely configurable in
software, it can be set up with a wide
range of user-defined parameters to
provide a unique set of performance
characteristics.
