EE522 is a stationary‑type energy‑storage equipment with 522.50 kWh energy capacity. Designed for fixed‑site deployment, it stores grid power and delivers stable AC/DC power output. It serves as a fixed power supply and charging solution for electric construction machinery. Adopting liquid‑cooled LFP battery modules with IP67 protection, it fits permanent job‑sites, industrial yards and depots where grid access is available, to support regular charging for electric loaders and other heavy‑duty EV equipment.
