The durability of a commercial truck and affordable replacement costs
Elon Musk shared new details about the durability of the Tesla Model 3 powertrain and batteries, as well as replacement cost of the battery modules.
First of all, the entire car was designed for durability, like it would be if it was a commercial vehicle:
“Model 3 drive unit & body is designed like a commercial truck for a million mile life.”
The battery modules alone would be good for about 1,500 charging cycles, which translates to 300,000-500,000 miles (480,000-800,000 km), depending on battery versions (Standard Range – Long Range).
” Current battery modules should last 300k to 500k miles (1500 cycles). Replacing modules (not pack) will only cost $5k to $7k.”
The battery capacity fade for those who drive a lot could cause the necessity to replace some of the battery modules (four) instead of the entire pack. The expected cost is $5,000-$7,000 (per module, we assume), probably also depending on the type (Standard Range or Long Range).
