The Rivitalo housing community, consisting of 15 apartments, faced the challenge of providing Electric Vehicle (EV) charging facilities without significant infrastructural modifications or common costs. One private customer in the community owned a Tesla and expressed the need for an EV charger. However, the housing company’s existing electrical lines were outdated, and plans for a comprehensive EV charging station were scheduled for the distant future. In order to solve this problem, Koticharge offered an innovative strategy that not only met the customer’s current charging needs but also created a foundation for future growth and sustainable electrification.

Challenges that the housing company faced

The housing company’s electrical lines were constructed in the 80s and lacked the capacity to support multiple EV chargers without significant upgrades. 
However one of the residents is a Tesla driver and he had the need for an EV charger to be installed. He agreed with the Rivitalo Housing Company on some certain conditions.
One of the conditions is that  the housing company wanted to make sure that the customer is the one who is bearing all the expenses.They wished to avoid any shared costs for the EV charging infrastructure.
Another important thing was to keep the heating poles for other residents so they can still use them to heat their cars.
Company planned to renovate the line in the future but not in the next 2 years, so they wanted to make sure that the customer could revert everything back to its original condition if needed.

Our solution

Our cutting-edge EV charging solution is intended to be minimal and does not require major electrical line renovations at the housing company. Instead of updating the entire electrical infrastructure,we can offer to install chargers in multiple stages. While our competitors require costly line renovation, we can establish the EV charging station without affecting the current electrical network by making use of cutting-edge charging technologies. With this technology we can put a fast 11kw charger among every 6 heating poles because it requires the same power as 6 heating poles combined. KotiCharge’s load balancing machine allows balancing the load among chargers and car heaters. This enables the installation of fast 11 or 22 kW chargers in multiple stages.
With KotiCharge,the power is in your hands as we seamlessly balance the load for fast charging without sacrificing heating infrastructure. If you want to install more chargers  in the future and renovate the line, our load-balancing device can support that too.
Moreover, to our customers we offer not only purchasing,but also a renting model. It means that the customer doesn’t have to pay for the charger itself, just for its usage. Our client-focused approach includes a flexible rental model that guarantees client happiness while protecting the interests of the housing company. When the housing company needs to renovate the whole line we just take the charger back without additional charges.
In this case there were two residents with the need of EV charging. They can share the charger. KotiCharge mobile app, which can be downloaded in AppStore and GooglePlay, provides a charging slot booking system for the hassle-free charging. Users can book a slot overnight up to 12 hours, and remove the cable in the morning when going to work. Once the slot ends, the cable is automatically unplugged so that the next user can plug their cable in. Considering the fact that our customer uses the charger only twice a week it will be very convenient to share it with the neighbor by using our booking system.

Conclusion

Our innovative EV charging solution not only allows the housing company to support EV owners without renovating the whole electrical line but also offers a flexible and cost-effective renting model. By prioritizing sustainability, adaptability, and customer satisfaction, we provide a future-ready solution that seamlessly integrates with the housing community’s needs while maintaining the integrity of the existing infrastructure.We also provide such features as spot-price invoicing to both private users and housing companies, as well as smart charging, potentially saving 40% of electricity cost.
