EV Tech Simplified: Battery IP Ratings Explained

Ratings For Solid-based Particles

Ratings For Fluid-based Particles

1 - Protection against objects greater than 50mm. 

1 - Protection against drops of water falling vertically, with limited ingress without harming the device as long as the flow is vertical.

2 - Protection against objects bigger than 12.5mm. 

2 - Uses an enclosure that’s 15 degrees off the vertical, and protects against water drops falling vertically. Still allows for limited ingress, but without causing harm.

3 - Protection against objects bigger than 2.5mm.

3 - Protects against water ingression in the form of a spray up to 60 degrees from the vertical. Still allows for limited ingress but without causing any harm. 

4 - Protection against objects bigger than 1mm.

4 - Protects against water splashes from all directions, with limited ingress, without harming the device.

5 - Protection against dust particles, and the object’s operation isn’t compromised even if there’s slight dust intrusion.

5 - Protection against jets of water, with limited ingress, without harming the device.

6 - Completely dust-proof.

6 - Protection against powerful jets of water, with limited ingress without harming the device.

7 - Watertight to the level where it can be immersed in a body of water between 15cm and 1m for up to 30 min. There would still be limited ingress but without causing any harm.

8 - Watertight to the level where it can be immersed to greater depths, that too for longer periods. The exact parameters will be mentioned in the device that has this rating, but the water dept is usually around three metres.
