There is no single IP rating every outdoor charger “should” have, because the right rating follows from the exposure — the water and dust your site delivers. A sheltered wall and an open post in a wind-swept car park are both “outdoors” but ask different things of an enclosure. This article gives the assessment method: name the exposure first, read the charger’s stated rating against it, then let the manual’s siting conditions arbitrate. For the digit-by-digit meaning of the ratings, our published comparison of IP54, IP65 and IP66 is the reference; this piece matches them to a real site.
Key Takeaways
- The right outdoor rating follows from the site’s exposure, not from a universal digit.
- Assess first: falling rain, wind-driven rain, splash-back, cleaning water and dust load are different demands.
- Read the stated rating for the complete unit, and let the manual’s siting conditions arbitrate.
- Where a listing states a pair such as IP65/IP66, plan against the lower figure or get the variant confirmed in writing.
Step One: Name the Water and Dust Your Site Delivers
Walk the site and list its actual exposure sources:
- Falling rain only — the unit sits under a canopy or deep eave, and weather reaches it mainly as vertical rain.
- Wind-driven rain — an open wall or post, wetted on every face by angled storms.
- Splash-back and standing water — hard ground bouncing rain up at the base, or a pooling low spot.
- Directed cleaning water — the site is hosed down or pressure-washed in routine cleaning.
- Dust and grit load — unpaved ground, agricultural or construction surroundings, or coastal air carrying salt and sand.
Most sites combine two or three of these. The list, not the postcode, is what the enclosure has to survive for a decade or more.
Step Two: Read the Stated Rating Against That List
| Your exposure list | What to read on the charger | What settles it |
|---|---|---|
| Rain and splash only | The second digit — the water rating — of the unit’s stated IP figure | The stated rating for the complete unit, not a component inside it |
| Directed cleaning water | Whether the water digit covers jets, and whether the manual permits washdown at all | The manual’s cleaning and siting instructions |
| Heavy dust or grit | The first digit — the solids rating — and whether the design is dust-protected or dust-tight | The stated rating, read against step one’s dust category |
| Standing water at the base | Whether siting (raised base, drainage, relocation) removes it | The site design; no rating in this class covers immersion |
Read the rating for the whole product, in the configuration you will install. A station can carry a modest enclosure figure overall while a sealed compartment inside rates higher — the figure that protects the site is the one stated for the unit as a whole. Our guide to whether portable chargers are waterproof covers the connection side of the same point.
Step Three: Respect the Conditions the Number Assumes
An IP rating describes a unit as tested: mounted in the orientation the maker specifies, its cable entries completed as designed, its connector holstered or capped between sessions. The rating does not follow the charger into a different installation. That is why the manual’s siting conditions — orientation, drainage, shelter — are part of the decision, settled with the installer before anything is fixed. A licensed electrician who has seen the site is the right arbitrator when the exposure list and the manual disagree.
Reading EVDANCE Ratings This Way
EVDANCE states a rating per model, and the method above is how to read them. The EV-ACT5006T wall charger states IP65/IP66 — where a listing states a pair, plan against the lower figure or get the variant’s rating confirmed in writing. Portables such as the EV-AC04001U state IP66; the floor-standing stations state IP54 and are sited as splash-protected equipment. None of these figures is a verdict for your site until your exposure list has been read against it — check the product range and put the list to the seller with the order.
Frequently Asked Questions
Is IP54 ever enough outdoors?
It can be, where the assessment supports it — a sheltered position whose exposure is splashing rather than jets. Whether that matches your site is what step one establishes.
Does a higher rating remove the need for shelter?
No. A higher digit widens what the enclosure tolerates; it does not repeal the manual’s siting conditions, and shelter still extends service life.
What about the connector — is it covered by the rating?
The rating belongs to the product as tested. Between sessions the connector’s protection depends on it being holstered or capped as the maker intends — a handling condition, not a digit.
