Back in February, we had an "infamous" blog post from Tesla declaring that:
For example, a Model S battery parked with 50 percent charge would approach full discharge only after about 12 months.
Yet the owner's manual states (page 25):
On average, the Battery discharges at a rate of 1% per day.
For example, over a two-week period (14 days), the Battery discharges by approximately 14%.
To protect against a complete discharge, the Model S enters a low-power consumption mode when the charge level drops to 5%. In this mode, the Battery stops supporting the onboard electronics to slow the discharge rate to approximately 4% per month. Once this low-power consumption mode
is active, it’s important to plug in the Model S within two months to avoid Battery damage.
So according to those figures in the owner's manual, if you park with 50 percent charge, then you'll enter low-power mode in 45 days and risk damaging the battery after just over a month from that point. Overall, this means that it takes less than 3 months to completely discharge the battery, after parking at 50%.
That's a far cry from the blog post's claim of 12 months. Any thoughts? Maybe there's a typo in the owner's manual for the discharge rates?
