People don't seem to understand that the battery chemistries optimized for cars is not the same battery chemistries optimized for grid storage though. You'll reduce the lifetime of your car substantially by cycling it every night.
- speedgoose 4y agoYou are downvoted but you are right. A Tesla model 3 battery is not designed to balance the electricity grid. Maybe it can be done in the future by using different chemistry, with some downsides, but the current cars would get destroyed by the many cycles.
- traviswt 4y agoAny usage will reduce a battery’s lifespan, but this isn’t a donation. The point of enrolling in a sharing program is you get compensated for letting the utility company use your resources. It should much more than offset the extra degradation. Degradation of lithium batteries is also not constant. It depends on several factors such as C rate, heat, and voltage. All of these factors would be far less during load sharing than just driving your car. And keep in mind most people wouldn’t want to share their entire batteries. They would want to save most for themselves. If they only offered 10% of their capacity for load sharing, then the shared usage would be far less than a full cycle.
