About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Relay vs. MOS for High-Current BMS: Which Is Better for Electric Vehicles?

When selecting a ​​Battery Management System (BMS)​​ for high-current applications like electric forklifts and tour vehicles, a common belief is that relays are essential for currents above 200A due to their high current tolerance and voltage resistance. However, advancements in MOS technology are challenging this notion.

In terms of application coverage, modern MOS-based ​​BMS​​ schemes now support currents from 200A to 800A, making them suitable for diverse high-current scenarios. These include electric motorcycles, golf carts, all-terrain vehicles, and even marine applications, where frequent start-stop cycles and dynamic load changes require precise current control. Similarly, in logistics machinery like forklifts and mobile charging stations, MOS solutions offer high integration and fast response times.Operationally, relay-based systems involve complex assembly with additional components like current transformers and external power sources, requiring professional wiring and soldering. This increases the risk of virtual soldering issues, leading to failures like power outages or overheating over time. In contrast, MOS schemes feature integrated designs that simplify installation and maintenance. For example, relay shutdown requires strict sequence control to avoid component damage, while MOS allows direct cutoff with minimal error rates. Maintenance costs for MOS are 68-75% lower annually due to fewer parts and quicker repairs.

Cost analysis reveals that while relays seem cheaper initially, the total lifecycle cost of MOS is lower. Relay systems need extra components (e.g., heat dissipation bars), higher labor costs for debugging, and consume ≥5W of continuous energy, whereas MOS consumes ≤1W. Relay contacts also wear out faster, requiring 3-4 times more maintenance annually. Performance-wise, relays have a slower response (10-20ms) and can cause power "stuttering" during rapid changes like forklift lifting or sudden braking, increasing risks like voltage fluctuations or sensor errors. In contrast, MOS responds in 1-3ms, providing smoother power delivery and longer lifespan without physical contact wear.

In summary, relay schemes may suit low-current (<200A) simple scenarios, but for high-current applications, MOS-based ​​BMS​​ solutions offer advantages in ease of use, cost efficiency, and stability. The industry's reliance on relays is often based on outdated experiences; with MOS technology maturing, it's time to evaluate based on actual needs rather than tradition.
