Future Trends in North American Transit Fleet Electrification
Key Ideas
  • Battery-electric bus charge capacity is increasing, enabling longer travel distances on a single charge.
  • Higher-powered charging infrastructure will be needed to support batteries with increased capacity.
  • Efforts to reduce the weight of electric buses while increasing battery capacity are crucial for operational efficiency.
  • Technological advancements like wireless en-route charging and improved heat pump technology are shaping the future of transit electrification.
In North America, public transit agencies are increasingly transitioning to environmentally sustainable, zero-emission models through transit fleet electrification. The future of transit electrification in the region is highlighted by several key trends: - Battery capacity for electric buses is set to increase, allowing vehicles to travel longer distances on a single charge. Companies like Proterra are developing buses with larger onboard battery capacities. - The need for higher-powered charging infrastructure will arise to support batteries with increased capacity, necessitating advancements in grid connection power capacity. - As electric buses evolve, efforts to manage weight alongside increasing battery capacity will be crucial for operational efficiency, enabling longer routes between charges. - The adoption of wireless en-route charging technology is on the rise, aiming to recharge buses without wired connections. Standardization in charging equipment is essential for broad implementation. Other notable developments in transit electrification include improvements in electric heat pump technology to reduce energy consumption, the importance of a sustainable energy grid, and the potential growth of fuel-cell electric buses with the availability of 'green hydrogen'. Efficient fleet management software will play a key role in maximizing the effectiveness of electrified fleet charging operations.
