Can I retrofit my existing EV with a J1772 inlet?

In brief: Indeed, you can retrofit an existing EV with a J1772 inlet, but it’s not a DIY job – you’ll need a professional’s touch and ensure it complies with all necessary safety standards and regulations.

The SAE J1772 plug has become something of an industry norm in several parts of the globe, including North America. It’s the go-to connector for Level 1 (120V AC) and Level 2 (240V AC) charging operations(1). This makes it a coveted feature for owners of older or foreign EVs lacking a J1772 inlet, who wish to plug into more ubiquitous charging infrastructure.

However, even though it’s technically possible to give your EV a J1772 makeover, don’t be fooled into thinking this is a mere snap-in-place job. It’s a task demanding a comprehensive grasp of your vehicle’s existing charging system, along with meticulous implementation to ensure every safety box is checked and no standard is overlooked. Given the high stakes – the risk of electrical mishaps, vehicle damage, or even personal harm – it’s a job best left to the pros.

Plus, the green light for such modifications may vary by locale, thanks to local regulations, and also hinge on your vehicle’s specifics. Therefore, before you set your retrofit plans in motion, make sure you’ve consulted with a bona fide EV technician or conversion expert. If they give the nod to the retrofit, remember, it should be carried out strictly by the book – no cutting corners when it comes to safety standards and guidelines.
