2 Implement Charge Inhibition With a Charger

The 0-V battery charge inhibition feature is not directly implemented in most battery chargers, but in can be approximated for many battery chargers with an I2C interface in systems with a host controller. With most chargers it would be limited to a 2-V battery charge inhibition feature. To implement this protection feature, first battery voltage needs the ability to be monitored.
