Guides for charger buyers
Practical, number-first writing from our engineering team — protocols, power selection and certification — so you can buy with confidence instead of relying on a sales pitch.
Buyer-side engineering, not marketing.
Every guide answers one question a real procurement decision turns on: which protocol will my back-end require, how much DC power does my site actually need, and what certification unlocks my target market. Each piece cites the numbers — OCPP 2.0.1 security features, the 4,380 kWh a 2-point efficiency gain saves per charger per year, and the $8,000–$60,000 certification cost bands — so you can shortlist with facts instead of brochures.
Written by the same engineers who specify our 96.5%-efficiency SiC power modules and our 30–360 kW DC line. New guides are added as buyer questions repeat in the field.
Read before you specify.
OCPP 2.0.1 Explained
What the device model, security and ISO 15118 readiness mean for charger buyers — and how 2.0.1 compares to 1.6.
Choose DC Power: 60 vs 120 vs 360 kW
A dwell-time and cost framework for site owners, with the efficiency math (94% to 96% saves ~4,380 kWh per charger per year).
Certification Guide: CE vs UL vs IEC
Costs ($8k–60k), timelines and regional requirements — CE for the EU, UL for North America, IEC globally.
