Next-Generation Battery Management System Architectures

Next-Generation Battery Management System Architectures

Konrad Lorentz, Product Manager Battery Management Systems and Emiliano Mediavilla Pons, Automotive Principal Functional Safety Architect (BMS) at NXP Semiconductors

DC fast chargers take between 30 to 45 minutes to charge the battery to 80 percent. This fast charging process generates a significant amount of heat, because the internal resistance to the high current generates a temperature rise. For a typical 400 V EV battery, therefore, the charging rate is limited by se

Application of Power MOSFET in Battery Management Charge-Discharge System

Song Liu, Sr. Applications Engineer, Discrete Products, Alpha and Omega Semiconductor, Inc., and Neil Zhang, Applications Engineer, Discrete Products, Alpha and Omega Semiconductor, Inc.

Power MOSFETs are required to be connected in series between the inside of the lithium-ion battery pack and the output load. At the same time, the dedicated IC is used to control the on and off of MOSFET for managing the charge and discharge of the battery, as shown in Figure 1. In consumer electronic systems, su

Power Supply Eliminates Electricity Metering Tampering

Silvestro Fimiani, Sr. Product Marketing Manager, Power Integrations

Tampering with an electricity meter can be as simple as placing a strong magnet near the power supply transformer. The applied magnetic field can disrupt power conversion and hinder the meter’s ability to accurately monitor electricity usage. Using a magnet to disable an electricity meter is especially eff
