Charging compatibility is not just about "plug in and charge." Willdigits used SECC on-site in Jakarta to conduct a frame-by-frame verification at the communication level across 13 brands, 26 vehicle models, and 232 vehicles.
During project support in Indonesia, the Willdigits team completed a practically valuable SECC compatibility verification: over two days, carrying communication sniffing equipment, they captured, analyzed, and verified SECC communication messages from multiple mainstream local EV models. The goal was not to confirm whether vehicles "could charge," but to check whether every communication interaction between the charger and the vehicle was accurate and stable.
13 brands, 26 vehicle models, 232 vehicles
At the Jakarta site this time, we observed the charging status of 13 brands, 26 vehicle models, 232 vehicles, covering Mercedes-Benz, BMW, Hyundai, Aion, BYD, Geely, XPeng, Chery, Wuling, SAIC Maxus, Aletra, Denza, MG, and others.
The results showed that all participating vehicle models were able to establish normal communication with the Willdigits SECC and complete charging successfully; the communication interaction of key parameters matched the vehicle-side expectations, with no issues such as "charging starts but communication is abnormal" or "parameters out of sync."
From "able to charge" to "charging better"
During testing, we noticed feedback from an owner of a certain vehicle model: at other stations, first-time startup occasionally failed, requiring re-plugging the charging connector to start. The team focused on capturing and analyzing that model's communication data, and made targeted optimizations based on the on-site charging process, improving the charging experience for users of that model at the station.
This is exactly how we understand compatibility optimization: not passively solving problems, but continuously discovering details, analyzing details, and optimizing details in real-world scenarios.
Real user feedback is another form of reliability verification
Beyond packet capture analysis, we also talked with local owners charging on-site. Several owners said: "The equipment at this station is very easy to use, and charging has always been normal."
For the technical team, message parameters are rational and test data is objective; but the "easy to use" in users' words comes from the long-term accumulation of real daily charging experience. An excellent charging system must not only pass tests in the lab, but also withstand the test of high-frequency use, complex vehicle models, and long-term operation in real operations.
A good SECC stands up to frame-by-frame analysis
Next, Willdigits will carry out similar on-site verifications in more markets, continuously capturing messages, analyzing details, listening to feedback, and feeding this frontline data back into product optimization.
