A battery management system for management and control of a plurality of rechargeable batteries connected in series A programmed central processing unit communicates with a plurality of battery modules and a bulk charger Each of the battery modules includes a rechargeable battery, a sensor node including a plurality of battery sensors and a microcontroller that processes signals generated by the battery sensors, and a direct current charger During a charging cycle the bulk charger provides a variable bulk charging current to the rechargeable batteries connected in series and each of the rechargeable batteries receive a charging current from individual direct current chargers positioned at each rechargeable battery During the charging cycle, the voltage and temperature of the rechargeable batteries are monitored by the programmed central processing unit by means of the sensor nodes and the bulk charging current reduced by one half when any battery voltage reaches a predetermined clamping voltage Once the bulk charging current is reduced to approximately 1 to 2 percent of the 3-hour discharge capacity for the rechargeable batteries, the bulk charger is turned off and the direct current chargers finish each battery charge independently

Battery management system

Battery management system is designed with MCU module, measurement module, alarm module, input module, output module and communication module. It can be able to timely report the states to the user in order to maximize using of battery storage capacity and cycle life.

Battery Management System

The condition of batteries (4) used to power one or more mobile radio units (3) of a mobile radio telecommunications fleet is automatically monitored. The mobile radio units (3) provide information regarding the condition of the battery (4) powering the respective unit (3), together with an identifier identifying the associated battery, to a data store (7). The data store (7) stores the information. This is done automatically, without the need for user input.
