Sounds like these 2 proposed enhancements in Baseline 530 will be met with cheers from the cold weather climates. Especially the first one relative to places where Karmas go into hibernation each winter:
"Currently, the 12v battery is not properly supported by the HV battery. In situations like long term storage or a degraded 12v battery, it can happen that the 12v battery runs flat as the parasitic losses even when the vehicle is turned off are still about 60 mA. This would result in a non starting vehicle. For this reason we currently advise to turn on the vehicle from time to time (please see the battery maintenance instructions on the Karma Forum) or place the 12v system on a battery tender charger. New software will allow the Auxiliary Power Module (APM) to keep the 12v battery charged by using the HV battery pack when a low 12v battery is detected. This keeps the 12v battery charged as long as there is sufficient power in the HV battery."
This one sounds nice for the cold weather folks too. Cold weather performance of the HV battery has been a standing concern of @Hockeydad
"Currently the ability of the HV battery pack to receive power through regeneration or release power at low ambient temperatures is less than optimal. The new software will improve how the HV battery pack manages incoming and outgoing power at low ambient temperatures."
