With Lenovo Thinkpads the i2c (aka SMBus) of the battery is connected to the embedded controller only (H8S in older models), which also controls charging and is powered as soon as the DC power supply is attached.
I guess you don't want more control over the battery but over the charger, e.g. to implement upper and lower limits for the battery charge. Cheers, Joerg
