Ah counter


The Ah counter system is designed to keep track of the remaining battery charge. This is accomplished by measuring the current flowing to/from batteries. By integrating the measured current over time, the Ah-counter calculates the remaining charge (ampere hours).

The Ah-counter samples the current 20 times per second and the resolution of the A/D converter is 16 bits. This means that with a measuring range of 2500A a current change of 76mA can be detected (theoretically).

The computer unit have 4 buttons and a display for presenting or changing values. The display and the menu system make the Ah-counter user friendly.

An auxiliary 16-bit input and a relay output are available for optional use.
A display unit can be supplied for remote presentation.
As an option a serial port is available for communication with external systems.
