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.

Why Does The EV Shut Down Unexpectedly? A Guide to Battery Health & BMS Protection

Electric vehicle (EV) owners often face sudden power loss or rapid range degradation. Understanding the root causes and simple diagnostic methods can help maintain battery health and prevent inconvenient shutdowns. This guide explores the role of a ​​Battery Management System (BMS)​​ in protecting your lithium battery pack.

Two primary factors cause these issues: general capacity fade from extended use and, more critically, poor voltage consistency among battery cells. When one cell depletes faster than others, it can trigger the ​​BMS protection​​ mechanisms prematurely. This safety feature cuts power to protect the battery from damage, even if other cells still hold charge.

You can check your ​​lithium battery health​​ without professional tools by monitoring voltage when your EV indicates low power. For a standard 60V 20-series LiFePO4 pack, the total voltage should be around 52-53V when discharged, with individual cells near 2.6V. Voltages within this range suggest acceptable capacity loss.

Determining whether shutdown originated from the motor controller or the ​​BMS protection​​ is straightforward. Check for residual power - if lights or horn still function, the controller likely acted first. A complete blackout suggests the ​​BMS​​ halted discharge due to a weak cell, indicating voltage imbalance.

Cell voltage balance is crucial for longevity and safety. A quality ​​Battery Management System​​ monitors this balance, manages protection protocols, and provides valuable diagnostic data. Modern ​​BMS with Bluetooth connectivity​​ enables real-time monitoring through smartphone apps, allowing users to track performance metrics.

Key maintenance tips include:

Regular voltage checks through BMS monitoring features

Using manufacturer-recommended chargers

Avoiding complete discharge cycles when possible

Addressing voltage imbalances early to prevent accelerated degradation Advanced ​​BMS solutions​​ contribute significantly to EV reliability by providing critical protection against:

Overcharge and over-discharge scenarios

Temperature extremes during operation

Cell voltage imbalance and potential failure

For comprehensive information on battery maintenance and protection systems, consult technical resources from reputable manufacturers. Understanding these principles helps maximize your EV battery's lifespan and performance while ensuring safer operation.
