Charging Case Studies and Delivery Record

Residential, education, healthcare, hospitality, office, industrial and renovation projects. Cases are anonymised at the client's request; same-type references available on request.

In this trade, a delivered project says more than any brochure. We do not do renderings — we describe what actually shipped: how we entered the site, what blocked us, how it was solved, and how the site is maintained today. Client names are anonymised to protect owners and partners; only fields useful for judging a project are kept.

What we disclose for every case

A charging project is judgeable from a handful of fields, so we standardise them: district (city or district level only), project type (residential / school / hospital / hotel / office / park / renovation), build year of the community, scale (households or bays), construction size (ports, or chargers and power), actual days from survey to power-on, key difficulties, and the delivery result — whether reinforcement was needed, what equipment was used, and which cooperation model.

Two delivery notes worth reading

New vs already-occupied communities

In new builds the goal is once-and-right: bays reserved, cable trays pre-laid, capacity reserved at 10–20%. In occupied communities the goal is no open-heart surgery: build a first batch on existing capacity, then expand in phases by measured utilisation instead of one giant bet.

Old community renovation

Renovation projects live on negotiation: no fixed bays, aged distribution rooms, sometimes no owners' committee at all. The public-charging-area model plus ordered charging plus a community-organised approval path is the repeatable pattern — details on the dedicated page.
