Abstract
Aiming at problem that there is no appropriate portable tool to measure liquid level of battery
a capacitive liquid level meter of battery is designed by using capacitor principle. Accuracy of product is enhanced by temperature compensation. The working principle and design method of capacitive liquid level meter of battery are introduced in details. The experimental results show that the accuracy of the capacitive battery liqnid level meter is prior to ± 3 mm
