Customer ServiceThe objective of the Leakage Current test is to verify that the electrical insulation used to protect the user from a Risk of Shock is suitable for the application. Leakage Current testing is used to verify that the product does not leak excessive current when contacted by the user. For medical equipment, the current flowing to ground is measured.
The leakage current of a battery can be measured by the battery test equipment. However, existing battery simulators are not accurate for small capacity Lithium coin batteries (such as 10 μA measurement accuracy in the dynamic model battery simulator of Keithley 2281S).
Here are some techniques for identifying current leakage in automotive systems: Battery Load Testing: Test the battery and charging system for excessive current draw, which could indicate current leakage. Use a battery load tester to simulate real-world conditions and assess the battery’s ability to maintain voltage under load.
If the current leakage is greater than this figure, then you should start looking for the cause. In most cases, finding a current leak in a car is done by removing the fuses. To do this, you need to know where they are, and what each of them is responsible for. As a rule, the relevant information is applied directly on the cover of the fuse box.
For this new market, battery leak testing is essential for electric vehicles, for battery packs any leakage can compromise safety, performance, and longevity of the system.
To check alternator leakage currents, you first need to disconnect the battery from the vehicle network (you can remove the negative terminal). Then disconnect two power wires from the alternator and connect them safely together. Depending on the connector type, you can use a bolt and nut of the appropriate diameter for the connection.
