ARROW EV Architecture
Polaris and others down the electric utility / SxS route , its interpretation of " adjacent segments " would see it " extending the Arrow architecture and EV systems to more distant 2W segments and related powersports categories ." It is clearly not for nothing that LiveWire is being birthed as an EV manufacturer , rather than a specifically motorcycle , scooter or PTW business . www . LiveWire . com
• At the heart of the LiveWire platform will be a " highly differentiated proprietary scalable modular EV system " that will allow LiveWire to be " fast to market and adaptive to future vehicle configurations ." This is claimed to deliver " lower investment for new models , lower incremental parts development ," and to give greater flexibility to respond to evolving regulations .
• The detail contained in the appendix of the investor prospectus is illuminating , and way more detailed than most OEMs are prepared to be - many are still treating their EV research as being alchemy meeting smoke and mirrors .
• Battery [ no mention of Swappable Tech at this stage ]
• Leading cell chemistry with optimized energy , performance and life , internally validated in real world accelerated characterization .
• High volume 21700 format cells enable rapid adoption of multiple suppliers ’ advancements .
• Standardized building blocks support broad range of motorcycleoptimized shapes and system voltages ( 50 / 100 / 350 / 400 +).
• Flexible thermal management approach air , liquid or refrigerant manufacturing and assembly equipment and processes optimized for modularity / scalability across full portfolio .
Power Electronics
• Integrated inverter and onboard charger with shared cooling circuit , minimizing complexity , connections , size and mass .
• Reduced number of ( and common ) microprocessors .
• Optimized cooling system liquid or air-cooled .
• Motor [ never call it an engine in EVs !]
• Increased power density with proprietary magnetics and direct-drive design .
• Common scalable configuration across portfolio , tailored to each application for desired performance and maximum efficiency .
• Housing fully integrated into chassis and suspension to optimize space , stiffness and weight with internal high voltage connections .
• Manufacturing and assembly equipment and processes optimized for modularity / scalability across full portfolio ; air or liquid-cooled , as needed per application .
