Energy storage containers are key equipment in power transmission and distribution systems. They mainly undertake the task of peak regulation by storing electricity during low-demand periods of the power grid and releasing electricity during peak-demand periods, which can effectively balance the power grid load and reduce electricity costs. During operation, the DC busbar inside the equipment remains under continuous current-carrying conditions for a long time, which is prone to heat accumulation. At the same time, it also faces the risk of short-term current overload conditions, which may easily lead to abnormal temperature rise. If temperature changes cannot be monitored in real time and potential hazards cannot be warned in advance, electrical safety accidents such as short circuits and insulation aging may occur, seriously threatening the stable operation of the energy storage system. Based on an energy storage container project in Hangzhou, this article focuses on the application limitations of existing temperature measurement solutions and optimizes the design of a stable and reliable temperature monitoring solution, providing technical support for the safe operation and maintenance of energy storage containers.

Elevators are typical potential energy loads. Under specific operating conditions, the traction machine motor switches from power consumption to power generation, continuously producing regenerative electrical energy. This primarily occurs in three scenarios: first, heavy-load downward travel, where the car's load exceeds the counterweight's mass, and gravitational potential energy drives the car downward, reversely rotating the motor to generate electricity; second, light-load or no-load upward travel, where the counterweight is heavier than the car, causing it to descend and pull the car upward, again reversely driving the motor to produce electricity; third, deceleration and braking, where the elevator decelerates before reaching the target floor, rapidly releasing its mechanical kinetic energy and converting it into electrical energy.

On July 10, 2026, Acrel participated in the 11th Southwest Building Electrical Annual Conference held in Chengdu, China. Centered on the theme of urban renewal, intelligent construction, and green building development, the event gathered industry experts to discuss the future of building electrical engineering. During the conference, Acrel showcased its Substation Automation System, Prepaid Utility Management System, AcrelEMS 2.0 Integrated Energy Efficiency Management Platform, and AcrelEMS 3.0 Smart Energy Management Platform. These solutions demonstrated Acrel’s expertise in power distribution monitoring, energy efficiency optimization, renewable energy integration, and intelligent energy management. Through continuous technological innovation and industry collaboration, Acrel remains committed to delivering reliable, safe, and sustainable energy solutions for smart buildings and enterprise microgrids.

As a core practice for the transition to clean energy, distributed photovoltaic (PV) power generation addresses the conflict between energy development and land resource constraints through innovative spatial utilization and technological advancement. Constructing PV power stations on idle land alongside expressways leverages their decentralized layout and clear ownership. This approach avoids competition for land with traditional agriculture and urban construction, while simultaneously achieving dual goals of land value appreciation and green power production. Anti-islanding protection serves as core equipment for secure grid operation. It prevents PV systems from continuously feeding power to the grid when grid power fails (the "islanding effect"), protects maintenance personnel, power grids and equipment, and maintains stable grid operation.

With the rapid popularization of the Internet of Things, artificial intelligence, cloud services, and big data technologies, the demand for computing power continues to rise, making computing power a core driving force for the development of the digital economy. Data centers serve as the core carriers for the operation of critical businesses in the digital industry, and a stable and reliable power supply system is the lifeline for ensuring the continuous and stable operation of data centers.
