Abstract (en)
[origin: WO9927628A1] An electronically controlled system for monitoring a battery bank, which has associated with each battery or small group of batteries or cells a measurement module which among other things measures the cell voltage and cell temperature, digitally encodes and serially transmits these values via an isolated bus to a central processing unit (CPU) which stores and analyses the values and provides an indication of the status of each battery and produces alarms when appropriate. Each measuring module will be kept in close physical proximity to the batteries it measures such that the temperature measurement requires no extra outboard circuitry and electrical isolation between the monitoring system and the battery voltage is provided as close to each battery cell as possible. A number of measurement modules may be connected to common buses and each central processing unit may receive inputs from more than one bus.
