Hello:
some one can help me to give information about a battery health montoring sensor for 200Ah lead acid battery which can be interfaced with Pic micro controller
Thanks
The best method I found is to use the Peukerts formula in the micro. Look at this link - **broken link removed** and wikipedia to find out more about the algorithm. The only issues I think you might have is the floating point power formula in the PIC and it will depend on your compiler. The best way to resolve it I find is to use fixed point but you will loose some accuracy in your calculation. I have use fixed point for the power function I found the code size reduce by 6K bytes.
Hello
I wana measure the internal resistance of a lead acid battery by applying an AC pulse and a DC load for few seconds but question are here
1.How much time is required for puls or AC sinal?
2 Frequency of AC signal/pulse?
3.How can we measure the change in voltage of battery terminal when the battery is connected?
4. how we calculate the batetery internal resistance and cacity remaining in battery?
Hello:
some one can help me to give information about a battery monitoring system to measure the voltage, temperature and current of 12v, 180Ah battery which can be interfaced with micro controller
Thanks
