How Can Port Terminals Be Adapted To Electric Vehicles?

The growth in the electric vehicle (EV) market must be viewed by operators and logistics terminals as a business opportunity that they should seize upon. Adapting is relatively easy, since the technical solutions in terminal infrastructures primarily mean providing battery-charging facilities. The main challenge consists in identifying when to make the investment to adapt to EV in order to capture the highest unit flow possible. The primary question that terminals have to answer as they plan their strategy is: Invest and wait? Or wait and invest?

What really changes?

The point of departure for this analysis is the fact that, as confirmed by numerous manufacturers, brands want to keep control over the first complete battery charge, which should be done under controlled conditions at the dealership after the vehicle has been delivered. This means that during the transport phase, EVs will be minimally charged to allow for the logistics of distribution, just like combustion vehicles now come with a small amount of fuel in their tanks to allow for movements in the terminal. If this is so, there is no expectation that terminals will have to carry out massive charging operations of all the EVs that arrive there in the future but instead just maintenance operations to deal with potential dead batteries during the transport and field storage phases. This clearly distinguishes the short term (with lower flows of EVs, which are not expected to remain in the terminals for long) from the middle and long term (with increasing flows and with terminals and storage lots acting as regulating warehouses and long-term storage for EVs). In any event, the main investment that should be borne in mind to adapt terminal infrastructures is related to the charging stations in vehicle storage areas. Therefore, in the short term, just having mobile charging systems will be enough. These are solutions that can be scaled to the flows of EV transport through the terminal and require a minimal investment. When planing investments in charging infrastructures, attention should be paid to the middle term. According to the EV sales rates and production, forecasts predict that within ten years it will be necessary to install permanent charging stations to optimise the battery-charging process of vehicles as they go through the terminal. It should also be noted that if the change in terminal infrastructure is expected to be modest, it is expected to be minimal in middle-term operations. For the purposes of terminal infrastructures, the long term should be viewed as a continuation of the middle term. In the long term, the significant difference among terminals will lie in their ability to make the most of the technological advances in charging and control solutions which will allow operations to be optimised and the associated costs to be lowered.

What should be done in the short term?

The growth in EVs’ sales and manufacturing share, both worldwide and domestically, is expected to take off in around 2023 and 2025, respectively. For this reason, even though the planning should focus on meeting the needs stemming from the large flows in the period 2025-2030, the short term should focus on port terminals’ revolution in electric mobility. In this first stage, large flows of EVs which could affect the operational planning of the different terminals are not expected, and they will instead arrive mixed with the traditional flows. Therefore, action protocols segmented by vehicle type are not expected. Accordingly, as the first step in the adaptative process, it will be enough to implement charging solutions in the terminals that allow for quick, mobile actions and can be transported to the place where the contingency has been detected inside the terminal. These are portable recharging systems or technical assistance vehicles equipped with a capacity to supply 3-5 vehicles. The charging should be quick if the goal is to solve the problem within a few minutes. Symbol signaling a electric car charger [Image by Nicola Sznajder]

Evolving towards the middle term

The main changes in the terminal’s operations, as well as the investments needed to adapt its infrastructure, should be planned for the middle term. This is when the flow of EVs through the main logistics hubs both domestically and internationally is expected to reach its most representative rates. First, in the middle term, the flows transported should be segmented (import/export), even though the energy needs by flow may barely increase compared to the short term. The milestone in this timeframe is not the installed power but the planning of a dedicated network within the terminal to meet the needs associated with recharging electric vehicles.

Terminals should have zones with facilities for both kinds of cargo management (slow and fast) by adding fixed solutions to the mobile equipment implemented in the short term. There is not much variety of technical solutions in fixed equipment today. For this reason, the most economically and functionally competitive solution suggested consists in fixed posts which use alternating current with connection systems adapted to the most common connectors at the time (the connectors used are expected to be standardised down to two models).

In a complementary fashion, the recommended solution to manage emergencies consists in installation quick charging stations in the repair shop or PDI zones, which will enable the demand for energy points to be handled when logistics processes do not allow for prolonged charging times.

The challenges of the long term

In the long term, the flow of EVs through ports is expected to continue growing in line with their growth in market share. We should note that this growth will be conditioned by the penetration of new propulsion technologies in the market, which will compete with electricity to replace conventional fuels.

The suggested long-term solution in port terminals is investing in vehicle silos by installing mobile sets of smart equipment in alternating current for ordinary cargo. The objective is for this equipment to be moved from zone to zone in the parking through a system of floating hoses anchored to the ceiling and equipped with crane arms which connect to the EVs, obviating the need to distinguish between loading and storage zones.

In a complementary fashion, recharging systems should also have dynamic charging balance control elements with multiple connections which allow the vehicles to be kept in at the charge levels recommended by the manufacturers.
