A Compact Home EV Charger solution is becoming essential as the electric vehicle industry grows and expands. A common challenge facing both fleet operators and private owners is: How to achieve commercial-grade high-speed charging without sacrificing valuable space?
This case study showcases how we helped a forward-thinking homeowner overcome this dilemma by integrating powerful commercial-grade charging technology into a Compact Home EV Charger solution.
Our client is a private EV owner with two electric vehicles and a small attached garage. He faced the following key challenges when charging at his residential property:
Speed vs. Size: He needed a home EV Charger capable of fast charging to accommodate the schedules of two vehicles. However, the space in his attached garage was extremely limited, making it impossible to fit a bulky, high-speed DC EV Charger.
Home Electrical Infrastructure: His existing home electrical service required an intelligent charger that could safely deliver high power without the risk of overloading or disrupting the use of other household appliances.
After evaluating multiple options, the client chose Penoda’s PDA-20/30/40kW DC Charger—attracted by its unique combination of commercial-grade performance, compact wallbox design, and intelligent load balancing technology that addresses both space and safety concerns
The Penoda PDA-20/30/40kW DC Charger was the perfect answer. It leverages proven, robust commercial-grade technology and packages it into a sleek, ultra-compact design perfectly scaled for residential environments.
