We’ve all had enough of looking for an available charging station, taking out the an adaptor and plugging in wires. Quite inconvenient, right?

Technology is making our lives easier continuously and now Electric Vehicle manufacturers and users will get the best out of mobility electrification: Convenience & Flexibility through WIRELESS CHARGING, which is based on theinductive power transfer technology. It uses electromagnetic oscillations to efficiently produce electric current that recharges a battery.

The EV wireless charging system includes two components: a Receiver mounted on the vehicle, a Transmitter installed on the parking by and connected to the electricity grid. Charging begins automatically every time you park over the system — no dirty cords to untangle and no chance of forgetting to charge!

As the convenience aspect of this technology will increase EV adoption rates, SAE International has released a new standard, which will ensure that all EV manufacturers will have one set of rules for wireless charging.

The J2954 Standard defines interoperability, electromagnetic compatibility, EMF, minimum performance, safety and acceptable criteria for the wireless power transmission (WPT) of light duty plug-in electronic devices. SAE has split wireless charging into 3 levels: WPT1 charging 3.7 kW, WPT2 (7 kW) and WPT3 (11 kW).

SAE J2954 has addressed grid-to-vehicle AC charging stating that bilateral energy transfer is also possible and we quote “evaluable for a future standard”. 

This continuous innovation and improvement of user experience will boost Electric Vehicle adoption as sustainability wouldn’t be a burden ⚡
