Issue

The following data objects (DOs) of LN ZBAT (now LN DBAT, see Tissue 945) use questionable abbreviations:
- Vol and VolChgRte use 'Vol' ('Voltage non-phase-related AC')
- Amp uses 'Amp' ('Ampere, current non-phase-related AC')
But in a battery there is DC not AC.

Proposal

- Use the abbreviations 'V' (for 'Voltage') and 'A' (for 'Current') from IEC 61850-7-4 instead
- Add a new abbreviation 'Drn' (for 'Drain')
- Rename ZBAT.Vol to DBAT.V
- Rename ZBAT.VolChgRte to DBAT.VChgRte
- Rename ZBAT.Amp to DBAT.ADrn
