IHEBS470K7D 470kW / 350kWh Liquid-Cooled Battery Buffer Charger

The Energic IHEBS470K7D is a 470kW / 350kWh liquid-cooled battery buffer charging system designed to combine battery energy storage with high-power EV charging.

The system integrates 350kWh of liquid-cooled battery storage, power conversion modules, intelligent power switching and multiple DC charging outputs into a single high-power charging infrastructure solution.

The Power Cube supports up to 400kW DC output power, with six DC charging outputs available through three dual-connector dispensers or six single-connector dispensers.

The system can also optionally integrate PV input and bidirectional AC feedback, allowing EV charging, battery storage, renewable-energy input and energy-management functionality to operate as part of a combined energy infrastructure solution.

Battery Energy Storage System The IHEBS470K7D integrates two 175kWh liquid-cooled battery packs, providing a total storage capacity of 350kWh. The battery system incorporates high-voltage control boxes, a two-level BMS architecture, Battery Pack BSU, and high-voltage control box BMU. This integrated architecture allows the battery storage system to work together with the Power Cube's power-conversion and EV charging infrastructure.

High-Power EV Charging The IHEBS470K7D is designed to act as a battery-buffered high-power EV charging system. Its DC output supports 150Vdc–1000Vdc, up to 600A per output, up to 6 charging outputs, and up to 400kW maximum DC output power. The system can connect to different charging dispensers, including configurations supporting GB/T, CCS, NACS, and CHAdeMO. The available connector configuration depends on the selected dispenser.

Power Conversion Architecture The Power Cube uses a modular power-conversion architecture. • DC/DC Conversion: Uses LCG1K0135G DC/DC converter modules rated at 40kW / 1kV. Up to 10 × 40kW modules support DC bus discharging and EV charging power architecture. • AC/DC Conversion: Uses LRG1K0100G AC/DC rectifier modules rated at 30kW / 1kV, supporting up to two 30kW DC-bus charging modules. • Bidirectional AC/DC Conversion: Optional LBG1K0120G bidirectional AC/DC inverter modules provide up to 2 × 35kW AC feedback power.

Solar PV Integration The IHEBS470K7D can optionally integrate PV generation into the battery-buffered EV charging architecture. Supported capabilities include MPPT, up to 1 × 40kWp PV input, up to 2 × 40kWp PV inputs, and maximum 80kW PV input. This enables solar generation to contribute to the wider EV charging, battery storage and energy-management architecture.

Intelligent Power Distribution A key feature of the IHEBS470K7D is its intelligent power switching matrix. Rather than permanently allocating individual power modules to specific charging connectors, the system dynamically allocates available modules between charging outputs. This helps maximize utilization of the available power-conversion capacity across multiple charging sessions.

Charging Dispensers & Connectivity Supported dispenser options include EXP200/250 FDC, EXP300-FDC, EXP400-FDC, EXP500-LDC/LLDC, and EXP250/300-FSW overhead dispenser. Available connector configurations: GB/T, CCS, NACS, CHAdeMO (dispenser dependent). Supported charging management functions include OCPP 1.6J, upgrade capability to OCPP 2.0, Plug & Charge, smart charging, power management, LAN 100M, LTE wireless connectivity, and WEB/APP maintenance backend.

Safety & Protection Features submerged aerosol fire extinguishing system, water fire interface, emergency fan, explosion-proof board configuration, fire-propagation-resistant structural design, temperature/humidity/smoke/combustible-gas sensors, door-access monitoring, and comprehensive electrical protections (overcurrent, short-circuit, overvoltage, undervoltage, RCD, insulation, overtemperature, reverse-polarity).

HMI & Metering HMI includes a 10-inch TFT touchscreen, RGB indicators, emergency stop, battery alarm light, and audible alarm. Metering includes 1 AC energy meter (optional MID-certified) and 1 or 2 DC energy meters (optional NMI Eichrecht-certified).
