Critical vehicle battery charge status monitoring unit measures voltage and quality parameter and compares them with threshold matrix to provide fault alert

摘要

#CMT# #/CMT# A critical vehicle battery (10) charge (15, 16) status monitoring unit measures voltage and quality parameters including voltage response, residual capacity and internal impedance change and processes (11) their time variation for comparison with a preset type related threshold matrix to operate a charging or exchange alert display (13). #CMT#USE : #/CMT# Charge status monitoring unit with critical state indication for vehicle batteries. #CMT#ADVANTAGE : #/CMT# Provides reliable indication of critical status and generates exchange requirement so avoiding both battery failure and unnecessary exchanges. Distinguishes different battery states. Enhanced status determination by the use of several parameters. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram of vehicle battery charge status monitoring unit. 10 : Battery 11 : On board power supply control unit 12 : Conductor 13 : Display 14a, b : Switches 15 : Generator 16 : External charger 17 : Conductor.
