With the industry's first Wi-Fi-enabled EV charging IC reference design
Remote monitoring and charging control available at home and public charging stations

TI announced that it is providing a reference design that can add Wi-Fi connectivity features to electric vehicle (EV) charging stations for the first time in the industry.

EV drivers can now remotely monitor their vehicles and control charging from anywhere with Wi-Fi, enabling a variety of use cases ranging from home automation to searching for nearby charging stations.


With advancements in battery technology and the implementation of relevant regulations by governments, the number of electric vehicles is rapidly increasing worldwide. However, more charging stations are needed for drivers to charge their vehicles more conveniently. A new reference design using TI’s SimpleLink™ Wi-Fi wireless microcontroller (MCU) technology enables the design of charging stations that allow charging during off-peak hours or recognize and notify users when a charging station is available.

A problem that hinders the widespread adoption of EV charging stations is that it takes too long to charge a vehicle. This reference design enables not only Level 1 charging compatible with household outlets but also Level 2 EV charging, which allows charging with higher currents (15A to 30A or more) in commercial buildings. Level 2 charging typically takes up to 8 hours to fully charge the car, allowing you to charge it while working.

In addition, TI plans to unveil a reference design for a Level 3 EV AC charger capable of 600V/400A in the second half of this year. In this case, charging time can be reduced to just 20 to 30 minutes. This is enough time to stop by a restaurant with Wi-Fi and a charging station during lunchtime to charge a car.
