Electrification of transport is gaining significant momentum worldwide and whether the fleet is a commercial fleet, a municipality fleet or a bus fleet, they all share common challenges in transitioning to an electric future. Here we explore those common themes and how depot digital solutions are key to successfully navigating the transition.<\/p>\n<\/div><\/div>\n\n

Fleets today are still predominantly fossil fuel based and the challenges and players are well known<\/h2>\n<\/div><\/div>\n\n
\n

Although the electrification transition is rapidly expanding fleets are still predominantly fossil fuel based. Such an ecosystem has been formulated over decades with well known and optimized components. It is typically based on diesel or petrol fuel which is relatively stable in price. The vehicles themselves use a technology which is over a hundred years old and is well understood in terms of operational parameters. The refueling infrastructure is relatively simple being pumps and fuel tanks and the time taken to refuel is measured in minutes. Most operators have well established and optimized vehicle and driver scheduling which is mediated by a series of interlocking IT systems for fleet management, depot management etc. This is the existing structure and can be seen below pictorially. What is really interesting though is what happens when we take this existing ecosystem and now consider the transition.<\/p>\n<\/div><\/div>\n\n

\n
<\/div>\n<\/div><\/div>\n\n
\n

Future fleets have a more complex ecosystem full of new players and new challenges<\/h2>\n<\/div><\/div>\n\n
\n

The challenges start with the change of fuel, from diesel to electric. Whilst diesel fuel was relatively stable in price, electricity costs can change rapidly during the day. This is due to the introduction of time of use tariffs where electricity is typically cheaper at night, more expensive around the early evening when people return home and solar dips. In many paces there are also \u201cdemand charges\u201d where power is more expensive at key times, again typically around early evening. In addition, it is now possible to consider using storage, on site generation, microgrids and virtual power plants to augment the grid connection. Whilst the vehicle cabin has not significantly changes its power train is completely different based on electrical motors drawing energy from a lithium ion battery. This brings in complexity related to range anxiety, route planning, driving optimization amongst others. The battery in the vehicle needs to be charged and this requires a charging infrastructure and associated electrical infrastructure. This charging infrastructure for a depot consists of the chargers and multiple front ends or dispensers for each charger. The technology of the charging infrastructure is very different to the diesel refueling infrastructure and requires different maintenance procedures. The chargers themselves need to be coordinated and scheduled and this scheduling needs to be coordinated with the vehicle and driver scheduling to ensure that each vehicle has ht right amount of energy, at the right time to complete its mission. And finally the new aspects of energy management and charging management required in an eDepot need to interface with the existing IT and the operational processes within the depot. But these challenges are not insurmountable and the complexity can be cut away by considering the key challenges and then addressing these with Digital solutions.<\/p>\n<\/div><\/div>\n\n

\n
<\/div>\n<\/div><\/div>\n\n
\n

The key challenges and how they can be addressed<\/h2>\n<\/div><\/div>\n\n
\n

There are three key challenges which if addressed can considerably increase the transition success for a fleet. First of these is maintenance of the charging infrastructure. In a typical fleet depot there may be hundreds of these, and it is impossible to monitor these by physically \u201cwatching\u201d them. There has to be a monitoring system in place which connects the chargers and relays their status so that they can be viewed remotely. Such a system should ideally be configured so that alerts can also be pushed via email or SMS to service teams or similar. Many faults can be cleared by resetting the charger, so the monitoring system should also be capable of sending remote commands to the chargers so avoiding the need for \u201cboots on the ground\u201d to clear faults. This connectivity also allows a rich datasphere to be developed, historical data can be analyzed to deliver valuable operational insights, detailed machine data can be evaluated to make troubleshooting more efficient.<\/p>\n<\/div><\/div>\n\n

\n

The second key challenge is around variable energy costs and grid connections. By controlling the charging using load management and energy management it is possible to significantly reduce the power demands and electricity costs for a depot. In my experience based on simulations of several real world fleet depots the power needs of a depot can be reduced by between 40 \u2013 50% when using optimized charging. Electricity costs see a typical saving of 15 \u2013 25% when using the optimized charging for the depots considered. These are key levers in making the business case for a depot. Power requirements for the depots drive the electrical infrastructure costs. Increased power requirements cost more and are a major driver of the depot capital expenditure. On the operating side electricity costs are the major driver of operating costs for the fleet so managing these are crucial. Digital solutions for charging and enemy management will be needed to control the charging schedules and associated energy flows in the depot. The good thing is that these build on the monitoring solution discussed earlier by bringing in the ability to control the chargers and overlaying this with layers of intelligence to manage the charging and energy. For more information on load management and why its important can be found here >>><\/a><\/p>\n<\/div><\/div>\n\n

\n

Lastly there is the need to integrate the energy and charge management into the existing depot operations. This covers not only the integration of the involved IT systems but also integration of the operational processes. Ideally, this starts before any chargers have been commissioned in the planning phase. The operations of the depot should be considered holistically together with the charging and energy management. In respect to the digital services it is essential that the charging and energy management systems can interface easily with the existing IT systems. This requires the digital solutions to be developed with an architecture that supports an open ecosystem whilst ensuring cybersecurity.<\/p>\n<\/div><\/div>\n\n
