The challenge of commercial and industrial energy storage often lies in its dual demands: for emergency use, it requires second-level response and instantaneous high power output; for energy saving, it calls for large capacity, long cycle life and continuous energy charging and discharging. It is difficult for a single type of cell to meet both requirements on one unit of equipment. Tianjin Plannano Technology Co., Ltd. offers a solution that integrates supercapacitors, LFP batteries and lithium titanate batteries into one commercial and industrial energy storage system. Each component performs its designated function, enabling both emergency power backup and energy conservation.
Three Types of Cells, Each with Its Own Role
Supercapacitors are high-capacity, fast-response members of the capacitor family, featuring outstanding second-level discharge capability. They handle instantaneous impact loads with minimal delay. LFP (Lithium Iron Phosphate) batteries excel in capacity and cycle performance, suitable for long-duration energy storage and energy transfer. Lithium titanate batteries, another type of lithium-ion battery, stand out with high-frequency charge-discharge performance and wide temperature adaptability.
The three cell types can be assembled into standalone systems separately or deployed in hybrid configurations, with proportions tailored to working conditions. Systems with heavy impact loads are equipped with more supercapacitors; those requiring frequent cycles adopt more lithium titanate batteries; and projects with high energy demand take LFP batteries as the main power source.
Instant Power Support for Emergency Scenarios
Second-level UPS backup power serves as a typical application. During grid fluctuations or equipment startup transients, the supercapacitors in the system kick in first with millisecond-level rapid response, followed by batteries to deliver sustained power support. The same logic applies to heavy-duty truck starting. In conditions of low temperature, power depletion and frequent start-stop cycles, supercapacitors shine by supplying instantaneous high current. Paired with LFP or lithium titanate batteries for energy reserve, the one-time startup success rate is greatly improved.
Stable Energy Charging & Discharging for Energy-saving Scenarios
For daily operation, the high-frequency response of the system in secondary frequency regulation comes from the combination of lithium titanate batteries and supercapacitors. Shared energy storage and wind power storage rely more on the large capacity and long cycle life of LFP batteries. The system stores surplus electricity generated during wind and solar curtailment, and releases power during peak consumption periods to realize peak shaving and valley filling, converting electricity price differences between peak and off-peak hours into tangible benefits. Multiple units can be connected in parallel for flexible capacity configuration, allowing the energy storage scale to expand gradually in line with project progress.
Simple System Management Despite Diverse Cell Combinations
Regardless of the cell mix, the scheduling logic remains unified. Equipped with a 3S management system and integrated local controllers, a single unit can independently perform peak shaving and valley filling, and support standalone microgrid and off-grid operation.
The integrated containerized design incorporates batteries, AC components, temperature control, fire protection and data monitoring. Designed for outdoor installation, it reaches an IP54 protection rating. The AC-side PCS adopts a modular structure for easy maintenance, and multiple PCS units can be paralleled on the AC side. Intelligent temperature control and bidirectional power conversion guarantee high efficiency. Charging supports constant current, constant voltage and constant power modes to extend battery cycle life.
From second-level emergency power backup to daily energy saving, and from secondary frequency regulation to shared energy storage, the Plannano commercial & industrial energy storage system covers most energy storage working conditions in commercial and industrial scenarios through the combination of three cell types. It delivers reliable power in emergencies and measurable economic returns in energy-saving applications. This embodies the value of Tianjin Plannano Technology Co., Ltd., leveraging its full industrial chain capability to develop hybrid energy storage system solutions.
