BMW ConnectedDrive contains two components - Service, Apps and Driver Assistance - that keep you connected and in command of every part of your life, all from behind the wheel. Discover why BMW ConnectedDrive is a BMW feature you can't live without. This means me that standard battery charging and PSU functions are different. Basic chargers can work in charging function only, which is not the best solution in my opinion. PSU mode is special function, when the device continously monitors current draw of the car and change the current accordingly. Output voltage is always the same.
Hi Anandraj,What´s your configuration on power groups and firmware version? N+1 or Grid?1.x or 2.x?The Blinking green led and status power-save, I belived this one is a standby.When you configure N+1, two PSU work and one Standby mode then If you configure Grid all PSU work together and all Green LED are glowing.Follow below documantion with Power Group configuration:PS:I found this information below, too.The power supply is providing no power to the system but can be powered upquickly in the event of another power supply failing. This mode saves powerin two ways:1. It reduces the power consumption of the PSU, as there is no output the PSUonly requires a small amount of power to keep the capacitors charged andcircuitry active.2. It increases the load on the remaining PSUs shifting them further on theirefficiency curves.Kind Regards,Marcus GOmes.
The bmw new series have a lot of moduls and the dry the batter on ignition switch on. With that reason they need over 14v and over a lot of amp to not have truble with them. But for most of the cars this witch you look will do the djob and all bi fine.mate - it is about 80A!!!
Do you realize 80A X 14V = 1120 W = 1.2KW - what the hell!!!the new BMW, AUDI, any car which you want - ON HOLD - will not need such power, if will be so - than for 5 min or 10 min doing the 'diag' of the car the battery will be lost!

BMW e60 for example, at ignition on, consuming about 20A.
When use ISTA P, the tension must be 13,5V (at OBD socket! That mean 14,5V on the battery in some cases) minimum, or programing of the modules wont start. In that situation consumption from the power supply is about 30-40A, because of the battery charging. When the battery is in poor condition, the consumption is about 50-60A for few minutes, i've seen even 80A.
So i think the power supply must be 100A minimum.But, for flashing the ECU with some OBD flasher, 50A power supply is good enough.Regards!
