How to stop an android device from being charged programmatically?

Question

Is there an Android API for stop charging even though physically the charging is on?

Answer 1

https://play.google.com/store/apps/details?id=es.guille.stopcharge uses echo "0" > /sys/class/power_supply/battery/device/charge. It works for me on a nexus 4 (rooted), as long as the device isn't fully charged (in a charging state).
