Unfortunately open sourcing is not an option without certification, cause vehucles will not be allowed to go on roads.

At least here in europe

A company in my city created an EV conversion kit for any cars years ago. As they could not get certification for all models, they made a partnership with the constructor and managed to have certification for only 1 model (Renault Master, a utility truck) and now the company is controlled by Renault (the constructor).

They indeed killed the competition…

Aaah then it is not a retreat it is just an excuse to fire people and whine about regulations

Check on youtube there is probably a video on how to open and do it your laptop model

Whaaat my laptop is 13yo, It is faster than new, just because I added ram and ssd 4 years ago
