When the HESC energy storage module uses supercapacitors as the core energy storage medium (which can be combined with different types of supercapacitors or adopt a differentiated combination of supercapacitors + supercapacitors, such as the collaboration of high-power and high-capacity supercapacitors) according to scenario requirements, its advantages and application scenarios focus on the "instantaneous response, ultra-long life, and high safety" characteristics of supercapacitors. At the same time, through modular design, its performance in power output and system stability is amplified, as follows:
"Ceiling" power density, millisecond-level power throughput capability
Supercapacitors themselves have an ultra-high power density of 1000-10000W/kg, and the HESC module can increase the instantaneous power output/absorption capacity of a single module to hundreds of kilowatts to megawatts through series-parallel topology optimization and voltage equalization control, while maintaining a response time at the microsecond level (10⁻⁶ seconds). For example, in scenarios requiring instantaneous release of high power (such as car sudden acceleration, instantaneous start of industrial equipment), the module can complete power output within 0.1 milliseconds, far exceeding lithium battery modules (millisecond-level response, power density usually below 500W/kg), perfectly matching "pulse-type" power demand.
Nearly "maintenance-free" cycle life, adapting to high-frequency charging and discharging
A single supercapacitor has a cycle life of more than 1 million times, and the HESC module extends the overall cycle life to 1-10 million times through redundant design and intelligent balancing algorithms (to avoid overcharging and over-discharging of individual capacitors). Moreover, under shallow charging and discharging conditions (5%-20% depth of charge and discharge), the life is almost unaffected. In contrast, lithium battery modules usually have a life of no more than 5 years in high-frequency scenarios with 100 cycles per day, while supercapacitor-based HESC modules can operate stably for 10-20 years, without the need to replace core components during the entire life cycle, reducing operation and maintenance costs by more than 80%.
Stable operation in a wide temperature range, "zero attenuation" in extreme environments
Supercapacitors have an operating temperature range covering -40℃ to 70℃. Through the optimization of cold-resistant/high-temperature-resistant electrolyte formulations and heat dissipation structure design, the HESC module can maintain rated power output in environments of -50℃ (such as outdoor equipment in extremely cold areas) or 85℃ (such as energy storage devices next to industrial furnaces), with a capacitor capacity attenuation rate of less than 5%. This feature enables it to directly adapt to harsh environments such as high altitudes, deserts, and polar regions without relying on complex temperature control systems, solving the problem of lithium batteries' capacity plummeting at low temperatures (more than 50% capacity loss at -20℃).
"No shortcomings" in safety, eliminating the risk of combustion and explosion
Supercapacitors use carbon materials as electrodes and inert electrolytes as media. The charging and discharging process is only physical charge migration without chemical reactions. Therefore, under extreme conditions such as overcharging, short circuits, punctures, and high temperatures, the HESC module will at most experience performance attenuation, without combustion, explosion, or toxic gas leakage. In contrast, lithium battery modules have the risk of thermal runaway due to their chemical properties, while supercapacitor-based HESC modules can be directly deployed in densely populated areas (such as shopping malls, hospitals) or explosion-proof scenarios (such as chemical workshops), and no additional redundant design is required for safety.
Flexible modular design, adapting to power requirements of multiple scenarios
The HESC module supports "building block" expansion. The capacity of a single module can be flexibly configured from 100F to 10000F, and can meet different voltage (DC 24V to DC 1000V) and power requirements through series-parallel combination. For example, small scenarios (such as electric tools) can use a single module; large scenarios (such as rail transit, port machinery) can achieve megawatt-level power output through parallel connection of dozens of modules, and there is no need to modify the original power supply system during installation, and the deployment cycle is shortened to 1/3 of that of traditional energy storage solutions.
"Regenerative braking energy recovery" in rail transit
Applicable scenarios: Subways, light rails, trams, etc. When trains brake (especially sudden braking when entering the station), instantaneous megawatt-level electric energy will be generated. Traditional resistance braking will convert it into heat energy and waste it, while lithium battery modules cannot withstand high-frequency high-power impacts.
Application value: The HESC module can complete the absorption of braking energy within 100 milliseconds (the energy recovered by a single train in a single time can reach 5-10kWh), which is stored and used for train acceleration when leaving the station. The recovery rate of single braking energy is increased to more than 80%, and the annual electricity saving of a single line can reach millions of kWh. At the same time, it reduces the problem of tunnel temperature rise caused by heat dissipation of braking resistors.
"Instantaneous power buffering" for industrial equipment
Applicable scenarios: Industrial machinery with frequent starts and stops, such as CNC machine tools, injection molding machines, and stamping equipment. The starting moment needs to consume several times the rated power (such as 30kW motor starting power reaching 150kW), which easily causes grid voltage drops and affects other equipment.
Application value: The HESC module releases high power instantaneously when the equipment starts, avoiding grid impact; it absorbs feedback energy when shutting down. A single device can reduce the grid capacity requirement by 30%-50%, and at the same time reduce the mechanical wear during motor startup, extending the equipment life.
"Efficient energy management" for special vehicles
Applicable scenarios: Port container trucks, mining dump trucks, hybrid buses, etc., which need frequent acceleration/braking and have high requirements for power response speed and cycle life.
Application value: When a bus accelerates suddenly, the HESC module provides additional power instantaneously, reducing the load on the main battery; it quickly recovers energy during braking, increasing the cruising range by 15%-20%, and the module life matches the vehicle life cycle (more than 10 years) without the need for replacement midway.
"High-frequency fluctuation suppression" in microgrids
Applicable scenarios: Off-grid microgrids (such as islands, remote base stations) composed of photovoltaics, wind power, and diesel generators. The second-level fluctuations of new energy output (such as gusts, cloud cover) will cause grid frequency oscillations.
Application value: The HESC module real-time suppresses high-frequency power fluctuations of 1-10Hz, making the output of diesel generators more stable, reducing the number of starts and stops (5-10 times per day can be reduced), reducing fuel consumption by more than 30%, and avoiding new energy curtailment.
