#CMT# #/CMT# The method involves measuring a voltage at terminals of a charged liquid lead battery, after applying a constant charging current (I) with preset intensity to the battery for a preset period. A determination is made whether the battery has a normal charging capacity if the voltage is lower than a low threshold. A determination is made whether the battery has a low charging capacity requiring its replacement, if the voltage is higher than a high threshold. A determination is made whether the battery has a degraded charging capacity, if the voltage is between the high and low thresholds. #CMT#USE : #/CMT# Method for determining charging capacity that corresponds to aging degree, of a liquid lead battery that is utilized for supplying electrical energy to a control device of a braking system or assisted steering system and for functioning of a thermal, electric or hybrid propulsion unit of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The method determines the charging capacity of the charged liquid lead battery in a simple, precise, and rapid manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a graph illustrating evolution of charging current of a battery and indicating the instant for measuring a charging voltage based on a charging capacity determining method. I : Constant charging current. |
