Implementing a workplace electric vehicle (EV) charging scheme involves strategic decisions that can significantly impact daily operations and future sustainability goals. Here are effective approaches to maximize the benefits:
Tailor Infrastructure for Long-term Needs
Installing EV chargers demands careful planning tailored to specific organizational needs. Naomi Nye, Sales Head at Drax Electric Vehicles, emphasizes the importance of customization: "There's no universal formula for charger installation. It's about understanding fleet requirements, existing infrastructure, and long-term goals." Factors like parking availability and vehicle usage patterns dictate charger type and quantity, impacting costs significantly.
Choosing the right charger type is crucial. For instance, slower AC chargers suffice for vehicles parked overnight, while faster chargers are essential for fleets with shorter dwell times between trips. Costs vary widely; a 7kW double-headed post costs approximately £1,500, while rapid units can exceed £35,000.
Managing power demand is critical. Solutions like load management systems balance charging speeds based on available power, ensuring efficient use without overloading the site. Alternatively, upgrading substations increases site capacity but requires substantial investment, recently mitigated by regulatory changes.
Integrate Renewable Energy and Storage
Organizations can enhance sustainability by integrating renewable energy sources and battery storage systems into their EV chargers. This approach not only reduces carbon footprints but also optimizes electricity costs. Solar panels, coupled with battery energy storage systems (BESS), allow excess solar energy to charge EVs overnight, reducing grid dependency and costs.
Nigel Dent, Sales Head at Connected Energy, highlights the benefits: "BESS maximizes renewable energy utilization, offsetting grid electricity and meeting decarbonization targets." Smart BESS solutions adjust to electricity tariffs, charging during off-peak hours and discharging during peak demand, thus lowering operational costs.
Expand Access for Greater Efficiency
Opening workplace charging facilities to external fleets and the public enhances cost-effectiveness and community support. Paul Hollick, Chair of the Association of Fleet Professionals (AFP), discusses the benefits: "Shared charging infrastructure promotes operational flexibility and efficiency." Digital platforms manage access and payment, ensuring seamless integration and priority access for primary users.
Several organizations have successfully implemented shared charging models. For example, Welch's Transport installed a 150kW supercharger accessible to external fleets, enhancing infrastructure utilization and supporting local electrification efforts.
Ensure Robust Aftercare for Minimal Downtime
Maintaining charger reliability is crucial for uninterrupted fleet operations. Graham Rowlands, Managing Director at Devitech, emphasizes proactive maintenance: "Selecting reliable chargers and complying with Smart Charging Regulations are essential." Remote monitoring and regular maintenance prevent downtime, ensuring chargers operate optimally.
Additionally, training fleet managers as first responders and integrating OCPP-compliant chargers facilitate efficient troubleshooting and maintenance.
