It was originally going to be $1000 so I was pleasantly surprised it's only $450.I've seen lots of posts recently recommending having a CHAdeMo adapter on board. I was shocked to see they cost $450 at the Tesla store. Why so expensive? Are there any better alternatives?
My CHAdeMO adapter has never been updated, despite my asking. Service tells me there are no firmware updates for the CHAdeMO adapter. I've had mine for several years now.My Tesla branded CHADeMO adapter firmware has been updated 3-4 times since I purchased it in May 2015. Doubt they’ll touch your Chinese replIca one if firmware changes to the BMS require a CHADeMO firmware update. ¯\_(ツ)_/¯
I'd be careful, as the CHAdeMO adapter has to perform some software emulation and communication between the vehicle and charger. I'm pretty sure use of this counterfeit Tesla adapter, were it to damage your vehicle's battery or degrade its range, will not be covered under Tesla's warranty and would probably invalidate your battery warranty entirely. Make sure before you use it.
Definitely not true (to you from the service center). Mine has been updated several times over the years at the Decatur GA Service Center
