With the tide of energy structure change, energy storage technology has become the passkey to balance power supply and demand and improve the absorptive capacity of renewable energy. As one of the leading suppliers of energy storage solutions in China, Shanghai Huijue Technology Group (hereinafter referred to as "Huijue") has built up an intelligent energy storage system of industrial and commercial energy storage, power grid frequency regulation, emergency power supply and other application conditions through independent research and development and technological innovation on the basis of virtue, and provided efficient, safe and green energy management services for global customers.

I. Technological foundation first: extensive integration of liquid cooling and intelligence

Huijue's root power storage system is based on smart liquid cooling technology, overcoming the limitation of air cooling systems, controlling the temperature difference of batteries to within ±0.5 ° C, increasing the efficiency of heat dissipation by more than 20%, and significantly increasing the battery cycle life to 8,000 cycles 1. For example, in Ningxia's 300MW energy storage power plant, the liquid cooling system enabled the project to sustain 98% conversion efficiency at a super-low temperature of -30 ° C, without encountering the problem of performance loss in low temperature.

Smart management is also a feature. The energy storage system of Huijue integrates an energy management system (EMS) that monitors battery conditions in real-time, optimizes charging and discharging strategies, and predicts grid load fluctuations with AI algorithms. In an industrial park in Jiangsu Province, the system saved the user 30% of each month's electricity expenses with the "peak cutting and valley filling" approach, and alleviated the pressure of peak load for the grid by 1.

II. realization of the scene: from industry to the whole of humans' livelihood

Commercial and industrial energy storage

For the high-energy use such as shopping malls and factories, Huijue launched modular energy storage containers. As an example, taking a textile enterprise in Zhejiang, after the installation of two sets of 1MWh systems, the enterprise takes the mode of valley power storage and peak power release to save more than 2 million yuan in electricity fees annually, and the payback period of investment is shortened to 4 years.

Frequency modulation and backup power supply

In Huijue's liquid-cooled energy storage system in Gansu Province's Jiuquan New Energy Base, the system coordinates with wind power and photovoltaic in unity to reduce the rate of wind and light abandonment from 15% to 3%, and engages itself in grid frequency modulation through millisecond response, increasing annual revenue by 5 million yuan 1. Additionally, its emergency power supply module can switch to energy storage power supply in 0.1 seconds when the power grid is disconnected, enabling main facilities such as hospitals and data centers to continue operating.

Breakthrough in overseas market

Huijue will ship 100MWH/1C container energy storage system to Northern Europe in 2024, featuring 20/40 feet prefabricated cabin design and with fire control, temperature control and monitoring subsystems. Customers in the Nordic region attributed its "advanced design and reliable quality", especially in polar climate, far better stability than local counterparts.

III. Sustainable value: a win-win for nature and the economy

Huijue's solution uses lithium iron phosphate batteries, which reduce life cycle carbon emissions by 40% compared to standard lead-acid batteries. In Guangdong green park project, energy storage system is integrated with PV, which reduces carbon emissions by 1,200 tons per year, the same as planting 60,000 trees1. From an economic point of view, after entering the power spot market and ancillary services, users can achieve a cost of 0.25 yuan KWH, which is 35% lower than the original energy.

IV. Future layout: Technological iteration and ecological co-construction

Huijue will launch the second generation of energy storage system in 2025, with the purpose of enhancing the liquid cooling efficiency and battery energy density, and the cycle life to more than 10,000 times. At the same time, the company is engaged in promoting industry standards development, promoting upstream and downstream collaborative innovation of the energy storage industrial chain, and building a "zero-carbon energy ecosystem" together with Ningde Times, Huawei and other partners.
