In the intricate landscape of EV infrastructure deployment, utility transformers stand as a cornerstone, facilitating the vital conversion and distribution of energy from the utility grids to charging stations. Simply put, substation transformers take transmission voltage and step it down to distribution voltage. Upon reaching a charging station site, the process commences with the connection of utility distribution networks or electric lines to a transformer, where the power is stepped down to 480 Volts.

However, even with a utility transformer, the voltage remains too high for a direct connection to an electric vehicle or EV charger. Additional components are needed, including primary or secondary metering, a main breaker, and distribution switchgear to effectively step down the power to charging posts or rectifiers.

Traditionally, utility companies have supported sites up to the meter. Yet, owing to funding constraints and the urgent need for rapid EV infrastructure deployment, the market has had to devise alternative approaches. Enter the Make-Ready concept from Utility providers. Make-Ready entails pre-wiring electrical infrastructure at a site by the utility, allowing for easy and efficient charger connection. This model includes service panels, junction boxes, transformers, meters, conduit, and wiring, not just the transformer and meter.

Driven by capital investment and lead-time considerations, owner-operators are also reimagining their approach by assuming ownership of the entire process, from transformers to chargers—a concept known as Reverse Make-Ready.

AK Power Solutions’ E2V Integrated Power Module (IPM) seamlessly supports Traditional, Make-Ready, and Reverse Make-Ready options. By integrating three essential components— Medium Voltage Breaker, Dry Transformer, and Low Voltage Switchgear—into a single unit, AK Power Solutions enables utilities or owner-operators to power sites swiftly and with fewer steps. The IPM’s innovative design eliminates coordination complexities, reduces installation time to just one day, and minimizes the footprint of charging infrastructure.

The evolution of power solutions in the era of electric vehicles signifies a paradigm shift in infrastructure deployment. With multiple options available to power EV sites (Traditional, Make-Ready, Reverse Make Ready), owner-operators have a range of choices that strike a balance between lead-time and investment.
