EV Fleet Management: With vs Without Telematics ROI Comparison
1. Without Telematics
Cost Savings
Fleets operating without telematics miss out on cutting energy costs by up to 45%. This happens because charging often takes place during peak-rate windows instead of taking advantage of cheaper off-peak tariffs.
The absence of utilisation data can lead to unnecessary expenses. For example, workplace EV charging installation costs make up 60% to 80% of total project expenses. When these installations are underused, the cost per charge averages £316.92, compared to just £4.55 for optimised, high-use setups. Without proper demand forecasting, businesses may invest in costly DC rapid chargers starting at £30,000 each, rather than more economical AC ports priced at around £1,100. Additional costs arise when upgrading power supplies - for instance, moving from single-phase to three-phase power can cost between £4,500 and £6,000. Without smart load balancing, exceeding the site's electrical capacity could make such upgrades unavoidable.
Emma Smith from Ratio EV notes: "Positioning charge points too far from the electrical supply often incurs unnecessary costs, while poor site planning can lead to ongoing inefficiencies".
These inefficiencies not only increase costs but also affect the overall performance of operations.
Operational Efficiency
Relying on manual processes leads to higher downtime and labour costs. Without automated load balancing, businesses risk overloading their electrical supply, which can result in system failures. Maintenance becomes more time-consuming and expensive as operators need to visit sites physically, rather than using remote diagnostics.
Battery health also suffers without proper monitoring. The "80/20 rule" - maintaining charge levels between 20% and 80% - helps protect lithium batteries from chemical stress.
According to Super B, "The high-voltage charging increases chemical stress inside the battery, which over time reduces its lifetime, so if you don't need the 100% capacity, don't charge it unnecessarily".
Without telematics to monitor the state-of-charge, batteries degrade faster, shortening the lifespan of the vehicle's most expensive component.
Additionally, logging business versus private mileage for Benefit in Kind (BIK) tax purposes becomes prone to errors without automated tracking.
Fleet-Trak warns: "The threat of non-compliance with HMRC can cause stress for management, and sometimes it can even cost the company more money than had the benefits been paid in the form of a higher salary".
Long-Term ROI
The lack of energy savings and operational inefficiencies significantly impacts long-term ROI. Data shows that nearly 80% of charging activity occurs at just 30% of stations, as the remaining 70% often suffer from poor utilisation due to the absence of data-driven forecasting. Without telematics, businesses cannot identify underperforming charge points or adjust their infrastructure to maximise efficiency.
Reactive maintenance adds to costs, as issues are addressed only after they occur.
Mer highlights: "Most of the costs connected to EV chargers are often related to the day-to-day operating expenses, not the capital outlay".
These ongoing expenses, combined with missed opportunities for government grants like the Workplace Charging Scheme, extend payback periods well beyond the typical 3 to 6 years seen in efficiently managed installations.
