𐄀 Technology Connection to Future
Against the backdrop of the deep advancement of the dual-carbon strategy and the accelerated construction of a national manufacturing powerhouse, China's new energy commercial vehicle and construction machinery industry has entered a new stage of large-scale and high-quality development. As core production tools, commercial vehicles and construction machinery feature heavy load, high frequency, extreme working conditions, and long service life. This determines that the connection system is far from a simple electrical accessory, but the power hub for equipment electrification and the nerve center for intelligentization, directly determining the reliability, safety, and operational efficiency of the equipment.
Based on independent core vehicle-mounted connection technologies and centered on scenario-based application adaptation, Yonggui Technology has developed a full range of products including high-voltage connectors, charging and swapping series, high-voltage wiring harnesses, intelligent control, power swapping, and customized products. It precisely breaks through technical bottlenecks and application pain points in complex working conditions, creates exclusive and systematic complete connection solutions, and escorts the electrification transformation of commercial vehicles and construction machinery equipment.
As production tools, commercial vehicles and construction machinery long face harsh environments such as heavy-load high-frequency vibration, sediment impact, alternating high and low temperatures, salt spray corrosion, and high-pressure water washing. Traditional connectors are prone to problems such as loosening failure, water ingress and short circuit, material embrittlement, and terminal corrosion.
Facing core industry pain points, we have broken the industry's single-product supply model and created a six-in-one full-link solution integrating high-voltage connectors + charging and swapping products + high-voltage wiring harnesses + control boxes + vehicle-mounted high-speed connections + customized products. It achieves full coverage from power transmission to signal control, from vehicle-end to energy replenishment scenarios, and from general models to special working conditions, providing customers with a systematic solution of one-stop configuration and full-cycle service.
The high-voltage connector series covers YGEV, YGEVM, IPT, and MSD (Manual Service Disconnect) series, and supports customized plastic and metal shell connectors to build a full-scenario adaptation matrix. Products focus on strengthening core performances such as high anti-vibration, strong sealing (IP67/IP6K9K), high and low temperature resistance, salt spray resistance, and sediment prevention. They are compatible with flexible outlet layouts in multiple angles such as straight and right angles, adapting to harsh working conditions of new energy commercial vehicles and construction machinery including heavy-load driving, frequent start-stop, and complex road conditions.With advantages of 360° full shielding against interference, double-stage locking to prevent loosening, low contact resistance, and low temperature rise, they meet high-power and high-current transmission needs, providing a one-stop complete vehicle supporting interconnection solution for the safe and stable operation of vehicle high-voltage systems.
The charging and swapping product series fully complies with GB, EU, and US standard technical requirements for commercial vehicles, creating a full-spec product matrix including various types of charging connectors and sockets to meet megawatt-level high-current transmission needs. A front-end fast power swapping solution customized for the domestic market efficiently adapts to various commercial vehicle power swapping scenarios and directly addresses energy replenishment pain points. For the core heat dissipation problem of super charging, we independently develop liquid-cooled super charging supporting products, achieving rapid heat dissipation through high-efficiency liquid cooling circulation technology and completely breaking through the temperature rise bottleneck of high-power charging. The interconnection solution from components to systems can fully meet all-scenario applications such as fast charging, power swapping, and station energy replenishment for commercial vehicles and construction machinery.
Designed for power transmission under specific working conditions of commercial vehicles and construction machinery, it adopts special high-voltage cables with high flexibility, bending resistance, high and low temperature resistance, oil resistance, and corrosion resistance, as well as precision crimping and welding processes. It strictly controls contact resistance and interface stability, maintaining excellent connection reliability even under harsh environments such as heavy-load vibration, sediment erosion, and salt spray corrosion.Customized wiring can be carried out according to the vehicle electrical architecture to realize full-link connection of core high-voltage components such as batteries, motors, electronic controls, and power distribution units. In response to the characteristics of long transmission distance, complex paths, and harsh working conditions of commercial vehicles, it strengthens anti-vibration, wear resistance, sealing, and electromagnetic compatibility performances, ensuring stable and reliable high-current transmission and providing an integrated link solution for the safe operation of the vehicle high-voltage electrical system.
We provide high-voltage box series such as BDU and PDU, adopting highly integrated and modular design that integrates high-voltage power distribution, overload protection, short-circuit protection, and status monitoring. It meets the centralized power distribution needs of multiple equipment for commercial vehicles and construction machinery. The product has a protection level of IP67 and above, excellent anti-vibration performance, and efficient heat dissipation capacity, adapting to harsh operating environments such as high and low temperatures, dust, and humidity. Optimized structural layout and electrical matching are implemented for the compact space, complex wiring, and large load fluctuations of commercial vehicles and construction machinery, realizing centralized management and control of the vehicle high-voltage circuit and multi-level safety protection. It effectively improves assembly efficiency and space utilization, and significantly reduces hidden troubles caused by multi-component docking.
We provide high-speed connection products including HSED series and Mini-Fakra series, fully covering all-scenario signal transmission needs of intelligent equipment. Mature adaptation solutions are available for in-cabin equipment such as domain controllers and intelligent instruments, as well as sensing peripherals such as radar, LiDAR, and cameras.The product covers coaxial and differential connector series to meet various rate requirements; supports long-distance stable transmission and complies with ISO 16750 anti-vibration grade and IP6K9K protection requirements; integrates power, coaxial, and Ethernet signals to optimize vehicle wiring, improve assembly efficiency and modular expansion capacity. Built for harsh commercial vehicle working conditions, it fully assists the intelligent transformation of commercial vehicles.
In response to differentiated application needs of special equipment and special working conditions, we provide customized development services such as control cabinet integration, charging socket box integration, PDU and high-voltage wiring harness assembly, all-in-one power connectors, megawatt-level charging and swapping products, GB quick-change charging sockets, and sheet metal boxes.Integrated solution design and customized development can be carried out according to customers' electrical performance indicators, installation space structure, and actual working conditions, precisely matching the development needs of non-standard scenarios, new vehicle platforms, and special equipment. It effectively solves common industry pain points such as insufficient adaptability, poor structural compatibility, and unqualified performance of standardized products under extreme working conditions.
