The idea for a standardized connection device for LEV components was born when ExtraEnergy prepared a battery test for Deutsche Post / DHL in 2002.
The project partners wondered what it would cost in terms of money and effort to change the battery supplier.
Deutsche Post at that time had 6,000 delivery pedelecs in daily use. If they changed battery technology, 6,000 battery chargers (50 EUR each) would have to be disposed of and replaced by new ones.
That would cost 300,000 EUR, just because the battery chargers were not compatible to different types of batteries (different chemistry / voltage).
A modern battery charger equipped with EnergyBus could have easily solved this problem. Once it is on the market it will charge batteries developed in the future if they use EnergyBus as well (backwards compatible). To buy such a battery charger will thus be a long-term investment.
The project partners agreed: Developing a standardized communication interface means saving huge amounts of money and rationalizing potentials and resources.
