After introducing the company Jungheinrich, an overview of the main electric powertrain components will be given. It is then analysed what the various interfaces between those components are and what their function is. It will further be analyzed which hazards can arise if said interfaces are not properly aligned and synchronized. Next, the pros and cons of "hand-picking" powertrain components (motors, inverters, batteries and chargers) from individual suppliers vs. using a fully integrated powertrain system from a single supplier will be discussed. Finally it is argued that OEMs should concentrate project risks where they can be best understood and controlled.

• Key facts on how and why a fork lift manufacturer (Jungheinrich) is also a Tier1 supplier for electric powertrains
• Main components of electric powertrain and the key interfaces between them
• What issues and hazards mismatched interfaces between powertrain components can cause
• Pros and cons of “handpicked” powertrain components vs. full integrated powertrain systems
• How OEMs can control project and design risks for electric machines by focussing on their core skills
