It’s crucial to make sure shared EV chargers are used securely and efficiently. Having access control in place means only authorised users can use the chargepoints. Access control solutions include RFID cards and mobile apps. These systems authenticate users before giving them access, protecting both the infrastructure and user data. 

Access control systems can also support accurate billing and usage tracking. 

Introducing a booking system for shared charging infrastructure can optimise charger use and help avoid schedule conflicts between users. 

With a booking system users can plan their charging sessions in advance. This makes sure they use chargepoints efficiently, especially during peak demand periods. This also allows users to charge at times that fit their needs, reducing downtime and improving operational productivity. 

Many booking systems also include features like notifications and reminders, which encourage users to stick to their scheduled time slots. These minimise delays and improve the efficiency of the shared infrastructure.  

When developing shared charging sites, you should consider the energy requirements and engage with the distribution network operator (DNO). You’ll need a detailed assessment of the site’s power availability to determine whether the existing grid infrastructure can support the planned chargepoints. This should account for the site’s electrical capacity, the anticipated load from the chargers, and any additional cabling or substations. 

Engaging with the DNO early in the planning process is crucial, especially for large-scale hubs requiring high-power chargers. It’s important to find out whether grid reinforcement is necessary and to give clarity on timelines and costs. Addressing these considerations early on helps prevent delays and will make sure the hub meets both current needs and future demand. 

Protecting user privacy is vital when managing data in shared electric vehicle charging systems, particularly under the General Data Protection Regulation (GDPR). To comply, you’ll need robust privacy protocols in place to safeguard personal information. This information includes user identities, charging history, and payment details. 

Measures such as data encryption, secure authentication methods, and regular security audits can help prevent unauthorised access or data breaches. These practices not only protect user privacy but also build trust and transparency between users and operators. 

By meeting GDPR, you’ll support the charging infrastructure to operate responsibly. It also helps you avoid fines and legal complications. 

To make sure your shared charging infrastructure operates reliably you’ll need to develop a maintenance plan. The plan should include regular inspections, routine maintenance, and timely repairs to keep all charging stations operating at peak efficiency.  

Preventative maintenance helps you identify and address potential issues before they lead to significant disruptions. This minimises downtime and makes sure users can rely on the charging facilities. 

In addition, offering 24/7 customer support means you can promptly resolve user queries and technical issues. With dedicated support staff available around the clock, users can get help with troubleshooting, scheduling conflicts, or payment concerns. This means they can access charging facilities without unnecessary delays. 

To make shared charging infrastructure a success, you’ll need to develop a fair and transparent pricing structure with site partners, such as public sector organisations and CPOs. A collaborative approach will help the pricing model meets the needs of all stakeholders. 

Pricing strategies could include: 

• Flat fees for unlimited access. 

• Pay-per-use rates for occasional users. 

• Set tariffs for specific user groups. 

• Variable tariffs that can be adjusted based on demand.  

To improve accessibility, you can set up a way to ‘whitelist’ non-paying users, such as emergency services or essential public service vehicles. For example, NatureScot’s shared chargers have a ‘whitelist’ of authorised vehicles. 

You can also streamline payments by using chargeback solutions, such as fuel cards from providers like Allstar or BP. These tools simplify the billing process, helping users to manage their payments and ensuring operators are paid on time. Chargepoint owners can use chargeback systems to monitor costs by user or department, allowing them to automate billing and reduce admin overheads.  

Sorting out liability and insurance helps you to mitigate the risk of damage during charging sessions. Adequate insurance coverage protects both users and operators from financial liabilities. This guarantees secure and reliable charging for everyone.
