What will be important is for battery cells and modules to be available from manufacturers for a reasonable price. --- End quote --- My advice when buying an electric car (whether it is hybrid, battery only or fuel cell) is to research if the battery is made up of modules which can be changed individually. That way a repair of a battery is not that expensive to begin with and you may not need the dealer to do this job. At this moment I'm seeing prices in the 800 euro ballpark for a refurbished battery pack for common Toyota hybrids. --- End quote --- And if you find one, it's basically guaranteed to be garbage due to lack of thermal management. So you get a battery which can be serviced but do not last long. |

This battery pack has been designed to be serviceable at a module level to keep repair costs low. |

Check Munro's ID.3 battery teardown. And you can buy the battery modules from companies that refurbish them. |

IMHO as minimum it will require firmware hacking, depending on how they are made, it's likely they cannot be reprogrammed. Also what about balancing? I'm not so sure that another module with different wear will work good enough. In theory you can replace them, in practice it's a big question if and when it will become possible. |
