Vehicle battery state of charge indicator |
摘要 |
A system for modeling a battery installed on a motor vehicle including a crank started engine, a voltage sensor connected to provide measurements of battery voltage and a temperature sensor providing temperature measurements provides for correcting capacity of the battery starting from the battery's rated capacity. A vehicle body computer implements the model through a stored program implementing an energy flow model of the target battery and stored data relating to model parameters including battery rated capacity and cranking current required for engine start over a temperature range. The stored program being responsive upon execution by the vehicle body computer for using the battery voltage measurements and temperature measurements during engine cranking to correct battery capacity.
