As electric vehicles (EVs) become more common, EV chargers are being installed in increasingly diverse environments—from indoor garages to commercial parking lots and outdoor public spaces. In these situations, the charger’s durability and safety become critical, especially against water, dust, and physical impact.
That’s where IP and IK ratings come in. These two international standards are essential for evaluating how well a charger can withstand environmental stress. In this article, you’ll learn what these ratings mean and how to choose the right EV charger based on your environment.
Defined by IEC 60529, the IP rating indicates a device’s resistance to dust and water.
First digit (0–6): Protection against solid particles
Second digit (0–9K): Protection against liquids
| Example | Description |
|---|---|
| IP54 | Dust-limited ingress, water spray from any direction |
| IP65 | Fully dust-tight, water jets from any direction |
| IP67 | Dust-tight, immersion up to 1 meter for 30 minutes |
Defined by IEC 62262, the IK rating measures how well a device resists mechanical impacts, expressed in joules (J).
| IK Rating | Impact Energy | Use Case |
|---|---|---|
| IK08 | 5 J (minor collisions) | Residential or protected locations |
| IK10 | 20 J (high impact) | Public or commercial installations |
EV chargers are exposed to:
Rain, humidity, and dust: Can corrode or short-circuit electronics.
Accidental or intentional impact: May damage casings or displays.
Extreme temperatures and cleaning: Can affect casing seals or wiring.
In public or high-traffic environments, chargers must be resilient and reliable. High IP and IK ratings not only enhance safety but also reduce maintenance costs and extend device lifespan.
| Environment | Recommended IP | Recommended IK | Why |
|---|---|---|---|
| Indoor Garage | IP54 | IK08 | Basic splash & dust protection |
| Outdoor Carport | IP65 | IK08 | Weatherproof and dust-tight |
| Commercial Parking | IP65 | IK10 | Public use with impact resistance |
| Street Charging | IP67 | IK10 | Waterproof and vandal-resistant |
| Industrial Parks | IP67 | IK10 | Harsh conditions and power washing |
