To authorize/cancel/program a battery charge via the network you must go to OS ONE.
Once connected, you must go to the "Settings" tab in the "Battery" section. You should then see a "charging controller" setting, and just below it a link allowing you to set the battery charging ranges. After clicking on this link, you will be able to schedule/withdraw the battery charges via the network. Remember to confirm by pressing the "OK" button otherwise your changes will not be taken into account.
Note: If you decide to schedule a battery charge, be aware that even if the battery is fully charged, it cannot be discharged until the end of the time slot.
