Example of conversion work items

The list below has been presented by Flavio Odorici during the project meeting on May 20 as one of the possible set of design issues and project work items entailed by a gasoline vehicle conversion into electric.

Although the project design choices are still to be defined and agreed, the list below represents a useful starting point and a design definition working tool. The upcoming project meeting will have the objectives to take decisions on the key design choices, deliver a definitive project item list and define the work packages to be assigned to the project teams.
