🚀 THE RESULT

I redesigned the entire charging journey — from parking to full charge

From finding a parking spot to a full charge. Every step rethought.

Key Learnings

Innovation doesn't mean the most advanced technology

My ideal hardware for reservation system exceeded the budget. But finding middle ground — semi-automated parking locks — still enabled the world's first EV charging reservation system without massive capital investment.

Technical constraints can unlock better solutions than perfect freedom

Instead of hiding EVALUE's counter-intuitive charging sequence, I transformed it into a guided experience using animation and haptics. The limitation became an opportunity for clear, deliberate user guidance that competitors lacked.
