Slow charge is 10% more than fast charge, fast charge can only be charged to 90%, the minimum battery power is 10%, so when using fast charge, it actually only uses 80% of the battery. Personally think that under fast charge (relatively slow charge) there is no damage to the battery.
In addition, when EQ1 is using fast charge, there is no warm air, and when using slow charge, the warm air can be turned on, and the slow charge and kinetic energy recovery may share the charging line.
Ant fast charge half an hour can reach 80% power, slow charge 7-8 hours can be fully charged.
