Data Buses and Battery Management

Overview

UV's, aerial and nonaerial, are now using professional level high-reliability CAN-bus and appropriate high speed and low speed interfaces for vision systems and battery management. Advanced battery control is essential to the UV's operational success. Overall efficiency and the ability to carefully monitor and control system health, and charge seamlessly are part of the UV's development. NXP has a wide offering of high reliability automotive systems that provide developers with CAN Bus, LIN, lightweight 100 Base-T1 two wire Ethernet, and specialty isolated battery communications options.
