Re: Gas gauge for car battery
@DaeJ - not a bad idea - I think maybe someone has done that already.

Re: Gas gauge for car battery
@RedDerek - for some of the POS cars I've driven (especially in the frozen tundra of Buffalo in the days of my youth) that would have been darned useful.

Re: Lead Acid Battery Guage
@rhayashi - Admitedly, not my area of expertise, so I will defer to the guys from TI.

Re: The easy way for SOC measurement
Yes fasmicro, but the error of voltage-based SoC occurs when disturbing the battery with a charge or discharge.

Re: Gas gauge for car battery
Instead of adding Solar Charge Bank near engine compartment, solar panel would be installed in the top of roof of vehicle. Energy will be stored directly to battery or secondary battery supply juice to Electronic module by using DC-DC or AC-DC converter.

Gas gauge for car battery
Look like a good IC for charge-discharge monitoring of Pb-acid batteries in applications such as power conversion (solar charge the bank during the day and convert during the night by usage). Now to see if they can create a gauge for the car battery - it should accurately tell the driver that the battery is going dead and one has xx days left before it starts to become a problem starting the car.

Lead Acid Battery Guage
There are too many variables, lead antimoney, lead calcium, pure lead, sealed/vented, special additives, different acid density? low resistance intercell straps? age, and temperature off the top of my head. Some folks tried impedance to guestimate charge too, didn't work. The rule of thumb of 2.0V @ C/20 (or was it 10) rate is about the best time to cutout the battery.

Brad,

 

Was it Benchmarq (acquired by TI, as I remember) that you used to work for?
