During the operation of ordinary traction elevators, 30%-40% of the electrical energy is converted into heat dissipation through braking resistance, which not only causes waste of energy, but also causes the temperature of the machine room to rise and accelerate the aging of electrical components. Traditional energy-saving solutions, such as feedback grid installations, have three major limitations:

Response delay: There is a lag in the energy exchange between the inverter and the power grid, which affects the smoothness of the elevator operation;

Harmonic pollution: inferior feedback equipment is easy to cause harmonic interference in the power grid and threaten the safety of other precision instruments;

Complex maintenance: Filter components need to be replaced regularly, increasing labor and spare parts costs.

Sichuan Jinshi Technology Co., Ltd. supercapacitor elevator energy-saving device adopts the closed-loop energy-saving mode of "real-time energy storage-on-demand release" to break through the bottleneck of traditional technology:

Millisecond-level dynamic response
The builtin highpowerdensity supercapacitor module can capture more than 97% of the regenerative power at the moment of elevator braking, and release it accurately when the elevator starts, reducing the power draw of the power grid.

Pure physical energy storage, zero harmonic risk
Different from the power feedback grid technology, supercapacitors store/discharge through the principle of physical polarization, without inverter process, completely eliminate harmonic pollution, and meet the needs of sensitive scenarios such as hospitals and laboratories.

Wide temperature and long life design
The device operates stably from -25°C to 65°C, with a cycle life of more than 1 million times (about 15 years), and the fully sealed structure design eliminates maintenance operations such as dust removal and electrolyte replacement.

These companies urgently need to upgrade their energy-saving solutions

Commercial real estate

Pain points: Elevators in shopping malls and office buildings run nearly 100 times a day, and the cost of electricity accounts for 20% of the total property expenditure;

Value: A single elevator saves 1520 kWh of electricity (measured data), calculated according to 1.2 yuan/kWh, the annual electricity cost is saved by more than 6,500 yuan, and the payback period is < 3 years.

Public hospitals

Pain points: Surgical ladders and hospital bed ladders need to run at high frequency for 24 hours, and traditional resistor heat dissipation aggravates the load of air conditioning;

Value: Energy recovery reduces the temperature of the computer room by 35°C, reduces the energy consumption of air conditioning by 10%, and simultaneously extends the life of the control system by 30%.

Industrial logistics park

Pain points: freight elevators start and stop frequently, and the failure rate of braking resistance accounts for 40% of the total elevator repair volume;

Value: The supercapacitor device reduces the braking resistance loss by 80%, and the annual maintenance cost is reduced by more than 12,000 yuan.
