Energy sharing
Built for energy communities
Why EV6 BESS
Designed for communities and projects that want to share PV surplus, cut electricity costs and run dynamic energy sharing across multiple meters.
Automotive quality for communities
At the core are second-life batteries from KIA EV6 with SK Innovation cells. Automotive origin means strict quality control and long service life.
Every pack is inspected and prepared for long-term stationary operation in community and commercial installations.
High-voltage power platform
Nominal voltage 530 / 660 / 705 V by variant and rated power 25 / 30 / 35 kW — ready for dynamic energy sharing, peak shaving and smaller-scale EV charging.
Slim profile without frame: EV6-58 171 × 146 × 14 cm, EV6-72/77 216 × 146 × 14 cm (H × W × D). IP 65/55, passive cooling with optional liquid-cooling connection.
Smart control and monitoring
Integrated web UI, Ethernet, operating statistics and charts, remote management. The BMS protects cells against temperature extremes, under/over-voltage and overcurrent, and keeps the pack balanced.
Communication via CAN / RS485 — expandable to 460 kWh in one rack, with multiple racks possible.
Three capacity variants
Choose capacity for community size and expected demand. Expandable up to 460 kWh in one rack; multiple racks possible.
