Electric buses and trains are becoming an increasingly common sight. And it is all thanks to the concept of smart mobility, which refers to the integration of advanced technologies and innovative solutions into transportation systems to enhance efficiency, safety and sustainability.
Many towns and cities are investing in electric vehicle (EV) infrastructure to replace their ageing fleets of diesel-powered buses and trains, which are significant contributors to air pollution and greenhouse gas emissions.
This electrification of our public transport systems follows similar shifts in other sectors, driven by the need to reduce emissions, improve energy efficiency and embrace sustainable practices. Not only is this shift changing our daily commute, but it is also seeing progression in electronic components and manufacturing processes, which need to adapt in line with this new technology.
So, what role do electronics play in the electrification of public transportation? And what do electronics manufacturers need to consider when designing and producing these components?
The role of electronics in public transport systems
The move towards electrified public transportation is propelled by four key factors: environmental benefits, operation cost savings, government incentives and technological advancements.
Electric buses and trains produce zero tailpipe emissions, significantly reducing the carbon footprint of public transportation. Equally, although the initial investment in electric vehicles and infrastructure can be high, the operational costs are considerably lower compared to their diesel counterparts. Plus, electric transport systems have fewer moving parts, resulting in reduced maintenance costs and longer lifespans. Many governments are also offering subsidies, tax incentives and grants to encourage the adoption of electric public transportation — making it financially viable for cities to invest in electrification projects.
However, perhaps the most important factor in the progression of public transport electrification is technological advancements. For example, developments in battery technology are making electric vehicles more efficient and capable of longer ranges — crucial for the practicality and reliability of electric public transportation systems.
From the latest battery technology and energy management systems to power electronics and telematics, these electronic components are essential for optimising performance and ensuring sustainability…
Energy management systems (EMS)
EMS are crucial for monitoring and managing the energy consumption of electric buses and trains. These systems ensure energy is used efficiently, minimising waste and maximising the range of the vehicles. By integrating renewable energy sources, such as solar and wind, EMS can further enhance the sustainability of public transportation.
Power electronics
Power electronics, including inverters and converters, are essential for controlling the flow of electricity within the vehicle. These components ensure electric motors receive the appropriate amount of power, enhancing the performance and efficiency of the vehicle.
Battery management systems (BMS)
BMS are vital for monitoring and managing the health of the batteries in electric vehicles. These systems ensure batteries operate within safe parameters, extending their lifespan and reliability. BMS also play a crucial role in optimising the charging process, reducing downtime and improving the overall efficiency of the transportation system.
Telematics and connectivity
Advanced telematics systems enable real-time monitoring and data analysis of electric public transportation fleets. This connectivity allows operators to track the performance of the vehicles, identify potential issues before they become critical and optimise routes for energy efficiency.
Considerations for electronics manufacturers
When designing and producing components for electrified public transportation systems, electronics manufacturers and original equipment manufacturers (OEMs) must take several key considerations into account:
Reliability and durability
Public transportation systems operate under harsh conditions and require electronics that can withstand vibrations, temperature variations and prolonged use. As such, components must be reliable, durable and manufactured to the highest quality standards.
Energy efficiency
Maximising energy efficiency is crucial for reducing operational costs and improving the sustainability of electric public transportation. As a result, electronics manufacturers must focus on developing components that optimise energy usage and minimise losses.
Scalability
As cities expand their electric public transportation fleets, the scalability of electronic components will become even more vital. OEMs should, therefore, design and manufacture systems that can be easily scaled up to accommodate larger fleets and more extensive infrastructure.
Integration with renewable energy
To further enhance the sustainability of electric public transportation, OEMs should focus on developing systems that can seamlessly integrate with renewable energy sources. This integration will reduce reliance on fossil fuels and promote the use of clean energy.
Compliance with industry standards
Finally, electronics manufacturers must ensure their products comply with industry standards and regulations. This compliance is crucial for the safety, reliability and interoperability of electric public transportation systems.
The electrification of public transportation is a pivotal step towards achieving smart mobility and integrating renewable energy into our daily commutes. The role of electronics in this transformation cannot be overstated, as they are essential for optimising energy efficiency, reducing emissions and ensuring the reliability of electric buses and trains.
