Over 80% Energy Recovery Efficiency Under Full Operating Conditions, Covering Wide Power Fluctuations
A single energy storage technology struggles to handle complex energy fluctuations: supercapacitors can quickly absorb instantaneous high power (such as energy from emergency braking) but have limited storage capacity; lithium batteries have large capacity but cannot withstand high-frequency, high-power impacts. Through an intelligent allocation strategy, HESC enables supercapacitors to handle instantaneous (millisecond to second-level) high-power charging and discharging (e.g., emergency braking, sudden loads), while batteries store continuous low-power energy (e.g., slow braking, long-term residual energy). This achieves efficient recovery across the full power range (from kW to MW levels) with an overall efficiency of 80%-90%, far higher than that of single technologies (usually below 70%).
"Dual Excellence" in Response Speed and Storage Capacity, Adapting to Complex Scenarios
Rapid response: Leveraging the microsecond-level response of supercapacitors, HESC can capture "fleeting" energy (such as kinetic energy released within 0.5 seconds of a car's emergency braking, or potential energy from sudden braking of a crane), preventing energy waste in the form of heat.
Sufficient capacity: Equipped with a battery system (e.g., lithium iron phosphate battery), it can store energy that lasts longer (such as kinetic energy from 30 seconds of slow braking when a subway enters a station, or residual energy from elevator round trips) and release it stably when needed (e.g., for starting or acceleration).
This "combination of fast and slow" characteristic allows it to adapt to full-scenario energy recovery needs, from "instantaneous pulses" to "continuous stability".
Prolonging Core Component Lifespan, Reducing Lifecycle Costs
Protecting batteries: High-frequency, high-power charge-discharge impacts are borne by supercapacitors, avoiding battery capacity degradation caused by "overcharging/over-discharging" or "high-current impacts" (the lifespan of lithium batteries is shortened by over 50% under charge-discharge rates above 10C), extending battery cycle life by 2-3 times.
Reducing mechanical losses: Replacing part of mechanical braking (e.g., brake pads, brake discs) with energy recovery lowers friction losses. For example, in rail transit, the frequency of brake pad replacement can be reduced by over 60%; in industrial equipment, maintenance costs for braking components can be cut by 40%-50%.
Strong Safety and Environmental Adaptability, Suitable for Harsh Scenarios
Safety: Supercapacitors have no risk of combustion or explosion. The battery part is controlled collaboratively with supercapacitors via a BMS (Battery Management System) to avoid overheating and overvoltage, making the overall safety superior to pure battery systems.
Environmental adaptability: Operating within a wide temperature range (-30℃ to 65℃), it can run stably in low-temperature (vehicles in northern winters, plateau rail transit) and high-temperature (industrial workshops, desert mining equipment) environments without complex temperature control devices.
Rail Transit: "Main Force" in Braking Kinetic Energy Recovery
Applicable scenarios: Urban rail transit vehicles such as subways, light rails, and trams. Their braking processes (especially deceleration when entering stations) generate large amounts of kinetic energy (the braking energy of a single train can reach hundreds of kWh), which is traditionally wasted as heat through resistors.
Application value: HESC can recover 60%-80% of braking kinetic energy, which is stored and then used for train acceleration when exiting stations or to power on-board equipment. For example, after deploying HESC on a subway line, a single train saves 150-200 kWh of electricity per day on average, and the annual electricity savings for the entire line can reach millions of kWh. Meanwhile, it reduces brake pad wear and lowers maintenance frequency.
Commercial Vehicles: Improving Range and Economy
Applicable scenarios: Commercial vehicles with frequent starts and stops, such as buses, logistics trucks, and port tractors. The instantaneous power generated by braking (especially emergency braking) can reach hundreds of kW. Traditional pure battery recovery is inefficient and affects battery life.
Application value: HESC quickly absorbs emergency braking energy through supercapacitors and stores slow braking energy in batteries, increasing the overall energy recovery rate to over 70%. For example, after installing HESC on electric buses, their range can be extended by 15%-20%, the battery replacement cycle is prolonged to 3-4 years (from the original 2-3 years), and the lifecycle cost is reduced by over 25%.
Industrial Machinery: Residual Energy Recovery and Load Balancing
Applicable scenarios: Industrial machinery with "high potential energy/high kinetic energy - braking" cycles, such as cranes, elevators, injection molding machines, and stamping equipment. For instance, the potential energy when a crane lowers a heavy object after lifting, and the kinetic energy during elevator operation, are severely wasted.
Application value: HESC can recover 50%-70% of residual energy from such equipment, which is then reused for the next startup or auxiliary operation. For example, after deploying HESC on port gantry cranes, a single device saves 80-120 kWh of electricity per day on average, while reducing the heat dissipation pressure of braking resistors and lowering energy consumption for workshop cooling.
New Energy Power Generation: Buffering Fluctuating Residual Energy
Applicable scenarios: New energy equipment with strong volatility, such as small wind power (e.g., distributed wind turbines) and tidal power generation.Their output power often fluctuates frequently due to changes in wind speed and tides, and excess energy (such as instantaneous over-generated power) is difficult to be directly integrated into the grid.
Application value: HESC quickly absorbs instantaneous over-generated power (second-level fluctuations) through supercapacitors and stores continuous residual energy (minute-level fluctuations) in batteries, which is then smoothly fed back to the grid, increasing the new energy absorption rate by 10%-15%.
