Electronic battery tester for vehicles, has microprocessor which is connected to removable digital module and response sensor which measures electrical response of battery

摘要

A response sensor (122) connected to a battery (102) through Kelvin connectors (112,114), measures the electrical response of the battery, when a function signal is applied to battery. A microprocessor (140) connected to sensor, determines dynamic parameter of battery, based on measured electrical response. The microprocessor is connected to a removable digital module (164) to receive or transmit data to/from module.
