A charger can check the battery condition within 30 minutes when plugged into an electric car

SK On and SK Signet announced on Nov. 24 that they had signed an MOU at Park One in Yeouido, Seoul to develop a battery diagnosis service utilizing electric vehicle chargers.

Through this agreement, the two companies plan to introduce the new service next year, allowing the users to diagnose the remaining battery life and charge level while charging their electric vehicles with an SK Signet charger. Next year, they also plan to develop diagnostic features for battery residual value estimation.

Since battery condition is related to a vehicle’s residual value and safety, electric vehicle users are always curious on learning about it. It is expected that SK On, a battery manufacturer, and SK Signet, a charger manufacturer, will be able to satisfy customer needs through their joint research. SK Signet will develop chargers that can collect battery data, and SK On will measure and analyze the battery data received from the chargers.

When a user plugs SK Signet’s rapid charger into an electric vehicle, SK On’s BaaS (Battery as a Service) analytics technology measures the battery life and condition in real time. The time required for diagnosis is 30 minutes for a 50kW charger, and the faster the charging speed, the shorter the time. The diagnosis results are displayed on the screen of the charger, currently under development by SK Signet, and also on the smartphone app, planned to be developed by the two companies.

SK On has been developing excellent BaaS analytics technology for battery diagnosis. Over the past three years, SK On has greatly improved its diagnostics performance by analyzing approximately 200 data items from approximately 4,000 electric vehicles.

“SK On has been working hard to spread battery diagnosis services and advance the technology,” said Lee Kyung-min, Head of e-Mobility Business Office of SK On. “We’ll continue to work with various partners to develop the infrastructure for the diagnostic services,” he added.

“Through a charger with the function to run battery diagnosis, customers will be able to enjoy a significantly safer electric vehicle lifestyle by checking the battery condition during charging,” Hugh Kim, CTO of SK Signet. He emphasized “By continuously providing a convenient charging experience, the product will practically advance the era of electric vehicles.”
