Method and apparatus for monitoring battery drain and starter current
First Claim
1. A current measuring system, comprising:
- means for measuring current, comprising;
means for smoothing a current distribution within the means for measuring current;
first means for interfacing to a vehicle power source being tested;
second means for interfacing to means for diagnosing a vehicle;
means for converting connected to the first means for interfacing to the vehicle power source, the means for converting being configured to convert a signal received from the first means for interfacing with the vehicle power source from a first form to a second form, wherein the means for measuring current is configured to provide data about a parasitic battery drain of the vehicle and a high current used by a starter motor of the vehicle; and
first means for processing connected to the means for converting, the first means for processing being configured to receive and analyze data converted by the means for converting;
means for diagnosing the vehicle based on data received from the means for measuring current, the means for diagnosing the vehicle comprising;
means for storing the data received from the means for measuring current; and
second processing means for analyzing the data received from the means for measuring current and for providing instructions to the first means for processing for analysis of a current drain of the vehicle; and
a power source controlled by the means for diagnosing the vehicle and configured to power the means for diagnosing the vehicle and the means for measuring current.

Abstract
A parasitic drain tester that measures a parasitic battery drain. A current measuring circuit includes a capacitor smoothing the current distribution within the circuit, a first interface connected to a vehicle power source and the capacitor, a second interface accommodating an outside connection for communication, a first processor connected to the second interface and the capacitor, the processor communicating with the second interface and performing analysis and calculation of the data received, and a converting unit connected to the processor, converting the signal received through the first interface from a first form to a second form. The first unit is connected to the current measuring circuit, and includes a memory storing information retrieved from the current measuring circuit through the second interface, and a second processor analyzing the information received from the current measuring circuit and providing instructions to the first processor through the second interface.
