Hi,
I’m currently working on a project which charges a 1000mAh lithium ion battery from a solar array using a maximum power point tracker and a simple charge controller (MAX1555). This allows a system load to be attached to the battery whilst charging takes place. I’m trying to find a way to measure the remaining charge level of the battery whist the battery is connected to both the charger and the system load. I’ve looked into various approaches such as coulomb counting but cannot seem to find a suitable solution. I’m primarily looking for a monolithic IC to perform this function communicating back to a central power management microcontroller using I2C for example however I’m open to suggestions.
Cheers...
