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 Lithium-Ion Batteries Fail to Charge After Discharge: Roles of Battery Management System

Many electric vehicle users find their lithium-ion batteries unable to charge or discharge after being unused for over half a month, leading them to mistakenly think the batteries need replacement. In reality, such discharge-related issues are common for lithium-ion batteries, and solutions depend on the battery’s discharge state—with the Battery Management System (BMS) playing a critical role.

First, identify the battery’s discharge level when it can’t charge. The first type is mild discharge: this triggers the over-discharge protection of the BMS. The BMS works normally here, cutting off the discharge MOSFET to stop power output. As a result, the battery can’t discharge, and external devices may not detect its voltage. Charger type affects charging success: chargers with voltage identification need to detect external voltage to start charging, while those with activation functions can directly charge batteries under BMS over-discharge protection.

The second type is severe discharge: when the battery voltage drops to around 1-2 volts, the BMS chip fails to operate, causing low-voltage lockout. Replacing chargers won’t help, but a solution exists: bypass the BMS to replenish power directly to the battery. However, this requires disassembling the battery, so non-professionals must exercise caution.

Understanding these discharge states and the BMS’s role helps users avoid unnecessary battery replacement. For long-term storage, charge lithium-ion batteries to 50%-70% and top up every 1-2 weeks—this prevents severe discharge and extends battery life.
