A range extended energy storage system series provides customers with a scalable product family where each model shares common components and control architecture. Injet HanCang offers the RESS series, a range extended energy storage system series comprising five models spanning two hundred to two thousand kilowatt hours of usable energy. The series approach reduces spare parts inventory for customers with multiple systems and simplifies operator training. This article presents the complete RESS series specifications, common features, and model selection guidelines.
The Injet HanCang range extended energy storage system series is named the RESS family. Each model designation indicates the usable battery energy in kilowatt hours. The series includes the RESS 200, RESS 400, RESS 600, RESS 1000, and RESS 2000. All models share the same control platform, remote monitoring interface, and generator controller. The battery chemistry is lithium iron phosphate across all models. The generator fuel is diesel standard, with natural gas and biodiesel options available on all models. The table below lists the complete series specifications. Model Usable Energy Generator Power Inverter Power Container Size Cooling Type Typical Autonomy Hours RESS 200 200 kilowatt hours 60 kilowatts 120 kilowatts 10 foot Air 2 to 4 hours RESS 400 400 kilowatt hours 120 kilowatts 250 kilowatts 20 foot Liquid 3 to 6 hours RESS 600 600 kilowatt hours 180 kilowatts 350 kilowatts 20 foot Liquid 4 to 8 hours RESS 1000 1000 kilowatt hours 300 kilowatts 600 kilowatts 40 foot Liquid 5 to 10 hours RESS 2000 2000 kilowatt hours 500 kilowatts 1000 kilowatts 40 foot high cube Liquid 6 to 12 hours The range extended energy storage system series is designed for modular expansion. Multiple units of the same model can be paralleled for increased capacity. Up to eight RESS 600 units can operate together, providing four point eight megawatt hours of storage and one point four megawatts of generator backup.
Every model in the range extended energy storage system series shares a common electrical architecture. The DC bus operates at a nominal voltage that scales with model size. The RESS 200 uses a two hundred forty volt bus. The RESS 400 and 600 use a four hundred eighty volt bus. The RESS 1000 and 2000 use an eight hundred volt bus. The common architecture includes a bidirectional inverter, a generator rectifier, a battery DC DC converter, and a controller. The controller runs the same software code across all models, with parameters adjusted for each model size. This commonality means that operators trained on one model can operate any model in the series. Spare control boards and sensors are interchangeable across models with the same bus voltage. The range extended energy storage system series also shares a common user interface. The touchscreen panel displays the same information format on all models including state of charge, generator status, load power, and historical data graphs. The remote monitoring website uses the same dashboard for all series models. Customers with multiple models see all systems on a single screen.
Each model in the range extended energy storage system series has unique technical specifications optimized for its intended application. The RESS 200 is designed for small commercial applications such as retail stores and small offices. The battery cell configuration is four series strings of forty eight cells for a total of one hundred ninety two cells. The generator is a three cylinder diesel rated at sixty kilowatts continuous. The inverter uses a three level topology with a peak efficiency of ninety seven percent. The system weight is four metric tons. The RESS 600 is the most popular model in the range extended energy storage system series, representing forty five percent of sales. The battery cell configuration is six series strings of seventy two cells for a total of four hundred thirty two cells. The generator is a four cylinder turbo diesel rated at one hundred eighty kilowatts. The inverter uses a five level active neutral point clamped topology for reduced harmonic distortion. The system weight is nine metric tons. The RESS 600 has been deployed in manufacturing facilities, data centers, and hospital backup power applications. The RESS 2000 is the largest model in the range extended energy storage system series. The battery cell configuration is twelve series strings of one hundred twenty cells for a total of one thousand four hundred forty cells. The generator is a six cylinder diesel rated at five hundred kilowatts. The inverter uses a modular design with three parallel three hundred fifty kilowatt modules. The system weight is eighteen metric tons. The RESS 2000 requires a reinforced concrete pad for installation due to its weight.
Injet HanCang has collected performance data for each model in the range extended energy storage system series from field installations. The table below shows average performance metrics across at least ten installations per model. Model Round Trip Efficiency Generator Fuel Consumption Battery Degradation per Year Mean Time Between Failures RESS 200 87.2 percent 2.6 liters per hour 1.2 percent 3500 hours RESS 400 88.1 percent 2.4 liters per hour per 100 kilowatts 1.1 percent 3800 hours RESS 600 88.7 percent 2.3 liters per hour per 100 kilowatts 1.0 percent 4100 hours RESS 1000 89.2 percent 2.2 liters per hour per 100 kilowatts 0.9 percent 4300 hours RESS 2000 89.5 percent 2.1 liters per hour per 100 kilowatts 0.8 percent 4500 hours The data shows that larger models in the range extended energy storage system series have slightly higher efficiency and lower specific fuel consumption due to economies of scale. The larger generator in the RESS 2000 operates closer to its optimal efficiency point more often than the smaller generator in the RESS 200.
Development of the range extended energy storage system series provided several technical insights. The first insight is that battery voltage matching to generator output reduces conversion losses. The RESS series uses a generator rectifier output voltage that matches the battery float voltage, eliminating one DC DC conversion step. This change improved efficiency by three percentage points compared to the prototype design. The second insight is that cooling system sizing must account for generator compartment heat soak after shutdown. The generator continues to radiate heat for thirty minutes after stopping. The RESS series cooling fans run for an additional thirty minutes after generator stop to prevent battery compartment temperature rise. The third insight from the range extended energy storage system series development is that state of charge estimation algorithms require different tuning for each model size. The larger models have lower internal resistance and different voltage relaxation characteristics. Injet HanCang developed model specific algorithm parameters validated through three months of testing per model. The fourth insight is that maintenance access improves when all service points are located on the same side of the container. The RESS series places all generator service points and all battery service points on the front face of the container, reducing required clearance from three sides to one side.
Selecting the correct model from the range extended energy storage system series requires analysis of three parameters. The first parameter is average load power. Multiply the average load in kilowatts by the desired autonomy hours without generator support. The result is the minimum battery energy. For a one hundred kilowatt average load requiring four hours of battery only operation, the minimum battery energy is four hundred kilowatt hours. The RESS 400 would be appropriate. The second parameter is peak load power. The inverter power must exceed the peak load. The RESS 400 inverter is rated at two hundred fifty kilowatts, suitable for peak loads up to two hundred fifty kilowatts. The third parameter is site access. The container size must fit through site gates and along access roads. The RESS 200 uses a ten foot container that fits on a standard flatbed truck. The RESS 2000 requires a low bed trailer and may need crane offloading. Injet HanCang provides a model selection tool on its website. Customers input their load profile data and receive a recommended model from the range extended energy storage system series. The tool has been used for over three hundred proposals with a recommendation accuracy of ninety five percent.
Yes, the RESS series supports mixed model configurations through a master controller that coordinates multiple units. Mixed configurations are common when customers expand existing installations. The master controller handles different battery state of charge levels across units.
No, generator replacement intervals depend on operating hours. The RESS 200 generator typically requires replacement after four thousand hours due to its higher specific load. The RESS 2000 generator can last eight thousand hours. Battery replacement intervals are similar across the series at eight to ten years under normal operation.
The standard warranty is transferable to subsequent owners with written notification to Injet HanCang. A transfer fee of five hundred dollars applies to process the ownership change. Extended warranties are not transferable.
Upgrading requires replacing the container because the larger models have different dimensions. However, multiple smaller models can be paralleled instead of replacing with one larger model. Paralleling two RESS 600 units provides one thousand two hundred kilowatt hours, more than a single RESS 1000.
Each system includes an installation manual, an operation manual, a maintenance schedule, electrical schematics, and a spare parts list. All documentation is provided in digital format on a USB drive and via the customer portal.
