Another Lithium Ion batteries question

I know nothing about the lithium batteries used for automotive use, but they are the battery of choice for Radio Control cars and planes. The fly in the ointment is the safety in charging these batteries. If not done safely and properly, they will cause early failure and a fire is a real threat.
So the charging system would have to be designed to safely charge them. Probably completely different than regular automotive batteries as we know them now.
