Ah yeah that is different then. I do wonder where these supply chains broke down specifically. Is it compute modules or specific chips/components? How feasible is it to have interchangeable compute modules with different internal implementations?
My car was available with I think six different batteries depending on options but they are also two entirely different chemistries (AGM and lead-acid). If there is a lead-acid battery shortage for some reason presumably everything could have been AGM.
- mschuster91 6y agoThe car itself doesn't care about the battery chemistry at all - it's actually not even a different chemistry, only a different way to build them -, it's always a nominal voltage of 12V and a charge voltage of about 14V. You can put in whatever battery you want, in theory. Practically, your choice will be influenced by: - price (lead-acid are cheaper) - usage frequency (AGM have lower self discharge rates and can stand up for a year or more without charging, while a lead-acid will grow sulfate crystals in a matter of months) - peak current capacity and temperature range (again, AGM are better, and you must use a battery that can supply the crank with enough amps... and note that the crank will need more power in colder climates) - capacity (obviously... depending on options like a beefy sound system, service lights, antitheft systems or seat heaters, you need higher capacity)
- mulmen 6y agoMy car absolutely cares about the battery chemistry because it optimizes the charging based on battery performance and capability. It also uses this information for the condition based service to indicate when the battery needs replaced and as an input to identify other electrical problems such as excessive discharge.
