The PTBP 130 kW / 257 kWh IC Energy Storage System with air cooling is a modular, high‑performance battery solution designed for medium‑scale commercial and industrial applications. It combines a rated power output of 130 kW with an energy capacity of 257 kWh, making it suitable for use cases such as peak shaving, load shifting, backup power, and renewable energy integration.At its core, the system employs high‑reliability battery modules configured to deliver stable DC output. These modules are arranged within a compact cabinet structure and are managed by an integrated battery management system (BMS). The BMS continuously monitors cell voltage, temperature, current, and state of charge to ensure safe and efficient operation. It also provides protection against over‑charge, over‑discharge, over‑current, and short‑circuit conditions.Air cooling is used as the primary thermal management method. Carefully designed airflow channels and high‑efficiency fans guide ambient air through the cabinet to remove excess heat from the battery modules and power electronics. Temperature sensors distributed throughout the system enable closed‑loop fan speed control, keeping temperatures within an optimal operating range. Compared with liquid‑cooled systems, air cooling simplifies installation and maintenance, reduces auxiliary equipment requirements, and lowers overall system complexity and cost, while still supporting reliable operation in typical indoor or mild outdoor environments.The PTBP 130 kW / 257 kWh configuration allows the system to deliver full power for roughly two hours under nominal conditions, which is well‑suited to many grid support and behind‑the‑meter applications. It can smooth fluctuations from solar PV or wind generation, store low‑cost energy during off‑peak periods, and discharge during peak times to reduce demand charges. In backup power scenarios, it can supply critical loads during grid outages, either independently or in combination with diesel or gas generators to form a hybrid power system.A dedicated energy management system (EMS) interfaces with the BMS and external equipment such as inverters, transformers, and site controllers. Through standard communication protocols, the EMS supports remote monitoring, data logging, performance analysis, and dispatch control. Operators can view real‑time status, set operating modes, and integrate the system into microgrids or building energy management platforms.The cabinet design emphasizes safety, with features such as robust electrical insulation, fire‑resistant construction, fault detection, and emergency shut‑down. The system is typically supplied as a pre‑assembled unit to streamline on‑site installation, requiring only electrical connections, communication wiring, and basic ventilation provisions.Overall, the PTBP 130 kW / 257 kWh IC Energy Storage System with air cooling provides a balanced solution that combines adequate power, practical energy capacity, straightforward thermal management, and flexible control functions, making it a versatile choice for commercial, industrial, and small utility‑scale energy storage projects.
