Zeon Charging reveals VinFast VF7's efficient charge curves: 70 kWh battery peaks at 105 kW, reaching 80% SOC from 20% in 25 mins on 120 kW DC. Explore this 532 km range EV's specs and performance.
Zeon Charging has shared detailed charge and time curves for the VinFast VF7 electric SUV, providing valuable insights into its 70 kWh LFP battery's real-world performance. The data highlights a peak power of 105 kW on a 120 kW DC charger, with a 20-80% state-of-charge (SOC) session taking just 25 minutes—making it a practical option for quick highway stops.
The curves emphasize the VF7's charging efficiency, though Zeon Charging notes variations due to ambient temperature, battery temperature, and other factors. This revelation comes as VinFast strengthens its India footprint with the VF7, a premium compact SUV blending style, range, and tech.
The charge curve plots power delivery (kW) against battery percentage (SOC), showing an initial high pull of around 120 kW at low SOC, peaking at 105 kW. As the battery fills, power tapers: 97 kW at 18% SOC, 102 kW at 32%, 103 kW at 47%, 104 kW at 60%, 104 kW at 71%, 105 kW at 78%, then dropping to 70 kW at 84% and 37 kW at 95%, before leveling at 3 kW near 100%.
This profile ensures safe, consistent charging without overheating, optimizing for LFP chemistry's stability. It's particularly useful for owners planning sessions at public 120 kW stations, common in India's growing network.
The time curve maps SOC against charging minutes, illustrating a near-linear rise from 20% to 80% in 25 minutes on the 120 kW charger. Starting at 20% SOC, the battery reaches 80% efficiently, adding significant range (roughly 300-350 km based on the VF7's 532 km full ARAI rating) in under half an hour.
This quick turnaround aligns with urban lifestyles, minimizing downtime compared to slower AC charging (9-11 hours full via 7.2 kW home wallbox).
Priced from ₹21.89 lakh to ₹26.79 lakh (ex-showroom), the VF7 offers two battery options: 59.6 kWh (438 km ARAI) or 70 kWh (532 km ARAI). Powertrains include single-motor FWD (174.3 bhp, 250 Nm) in Earth and Wind trims, or dual-motor AWD (348.6 bhp, 500 Nm) in Sky variants for 0-100 km/h in 5.8 seconds.
Variants—Earth, Wind, Wind Infinity (adds panoramic glassroof), Sky, Sky Infinity—feature Level 2 ADAS (adaptive cruise, lane keep, emergency braking), 15.6-inch touchscreen, Harman Kardon audio, ventilated seats, and a 10-year/2 lakh km battery warranty. No bi-directional charging (V2L or V2V) is available.
The VF7's 400V architecture supports CCS2 ports, with AC up to 7.2 kW. At 4.55 m long with 537L boot space, it's a versatile rival to the Tata Curvv EV and Mahindra BE 6
This data from Zeon Charging underscores the VF7's practicality, aiding VinFast's expansion in India with more models and infrastructure in 2026.
