Against the backdrop of a global push for energy transition, the new energy industry is thriving, with various new energy devices such as solar photovoltaic systems, energy storage devices, and new energy vehicles continuously emerging and evolving. Behind the efficient and stable operation of these devices, Gordon solid state relays play an indispensable key role.
Analysis of the Technical Advantages of Gordon Solid State Relays
Gordon solid state relays utilize the electrical, magnetic, and optical properties of electronic components to achieve reliable isolation between input and output. They eliminate the mechanical contacts found in traditional relays, using the switching characteristics of high-power transistors, power MOSFETs, and unidirectional/bidirectional thyristors to connect and disconnect the controlled circuit without contact and without sparks. This design fundamentally avoids failures caused by contact wear, oxidation, and sticking, greatly extending service life and significantly reducing maintenance costs and downtime, which is a critical advantage for new energy devices that require long-term stable operation.
Gordon solid state relays are encapsulated in insulating materials, providing excellent moisture-proof, mold-proof, and explosion-proof characteristics. This enables them to operate stably in complex and harsh environments with high temperatures, high humidity, dust, and even flammable and explosive risks, laying a solid foundation for the application of new energy devices in various extreme scenarios. Whether in desert photovoltaic power stations plagued by extreme heat and drought or in coastal energy storage projects with high humidity and salinity, Gordon solid state relays can handle these conditions with ease, ensuring normal operation of the equipment.
From a performance perspective, Gordon solid state relays have extremely fast switching speeds, capable of controlling circuit connections and disconnections within milliseconds to microseconds. This feature is particularly advantageous in scenarios where new energy devices require high control precision and response speed. For example, in the rapid charging of energy storage devices, they can precisely control the current on and off, ensuring a safe and efficient charging process while extending battery life. Moreover, the contactless and spark-free design of Gordon solid state relays prevents electromagnetic interference, which is beneficial for ensuring the normal operation of new energy devices and surrounding electronic equipment. In new energy systems, where various electronic devices are present and the electromagnetic environment is complex, the low electromagnetic interference characteristics of Gordon solid state relays effectively reduce the impact of electromagnetic interference on the system, ensuring stable operation of the entire new energy system.
Key Applications of Gordon Solid State Relays in New Energy Equipment
Applications in Solar Photovoltaic Systems
In the manufacturing process of solar panels, Gordon solid state relays are used to control the heating elements in anti-reflective coating machines. With their rapid switching response speed, they can precisely adjust the on and off states of the heating elements, achieving accurate control of the coating temperature, ensuring uniformity and quality of the coating, and laying the foundation for the production of high-performance solar panels. Additionally, during the power generation process of solar photovoltaic systems, Gordon solid state relays serve as a medium between solar panels and batteries, playing an important role. On one hand, they protect solar panels from overvoltage during winter, preventing potential damage to the panels due to converter idle load, thereby increasing the power generation capacity of the solar panels; on the other hand, when the battery is overcharged, they can promptly discharge it to maintain stable battery performance, ensuring the efficient operation of the entire photovoltaic system. Furthermore, in the critical device that converts solar energy into electrical energy and connects to the grid—the solar inverter—Gordon solid state relays can reliably handle high currents, precisely control the current, and ensure efficient and stable conversion from direct current (DC) to alternating current (AC), achieving seamless integration with the grid and maximizing the overall energy output and conversion efficiency of the photovoltaic system.
Applications in Energy Storage Devices
During the charging and discharging processes of energy storage devices, Gordon solid state relays act like a precise “conductor.” During charging, they can quickly respond to control signals, accurately adjust the charging current and voltage, ensuring that the battery charges under optimal conditions, effectively avoiding irreversible damage from overcharging. When the battery is full or an abnormal situation occurs, they can rapidly cut off the charging circuit in a very short time, fully ensuring battery safety. In the discharging phase, they can also accurately control the discharging current based on load requirements, achieving stable output of electrical energy to meet the discharging needs of different scenarios. The Battery Management System (BMS) is the “brain” of the energy storage device, while Gordon solid state relays are its most capable assistants. They are responsible for real-time monitoring of key parameters of the battery, such as voltage, current, and temperature. Once abnormal parameters are detected, they can immediately take decisive actions, such as cutting off the circuit, preventing overvoltage, overcurrent, and overheating, providing comprehensive and reliable protection for the battery. Additionally, in battery balancing management, Gordon solid state relays achieve balance among individual batteries in a battery pack by precisely controlling the current flow, effectively extending the overall lifespan of the battery pack and enhancing the overall performance and stability of the energy storage device. In the power conversion phase of energy storage devices, Gordon solid state relays play a key control role, ensuring efficient transmission and conversion of electrical energy between AC and DC. For example, when storing renewable energy such as solar and wind energy into batteries, as well as inverting the energy from the batteries for load use, they ensure that the conversion process is stable and smooth, providing solid support for the efficient operation of energy storage devices during energy storage and release processes. Furthermore, when energy storage devices encounter faults such as short circuits or overloads, Gordon solid state relays can act quickly, instantly cutting off the faulty circuit, preventing the fault from expanding, and fully protecting the safety of the entire energy storage system. They can also achieve fault isolation, greatly facilitating staff in quickly locating and troubleshooting faults, significantly improving system maintenance efficiency and reducing downtime and losses caused by faults.
Applications in New Energy Vehicles
In the battery management system of new energy vehicles, Gordon solid state relays are used to control the on and off of the charging circuit. When the vehicle is charging, they can quickly respond to commands from the BMS, precisely controlling the charging current and time, ensuring that the battery charges quickly and safely. In cases of overvoltage or overcurrent, they can rapidly cut off the charging circuit within milliseconds, effectively preventing safety hazards from overcharging and extending battery life. In the power system of new energy vehicles, the stable operation of the motor is crucial. Gordon solid state relays are used to control the starting, stopping, and speed adjustment of the motor, and their rapid switching response speed allows for smooth starting and stopping of the motor, reducing the impact of starting current on the motor and battery, while precisely adjusting the motor speed to provide suitable power output based on vehicle driving needs, enhancing vehicle performance and driving comfort. Additionally, in the auxiliary systems of new energy vehicles, such as air conditioning and lighting circuits, Gordon solid state relays also play a reliable circuit control role, ensuring stable operation of these auxiliary devices and providing a comfortable environment for passengers.
