Should New Energy Vehicles Be Fully Charged?

[DeMiguel]

New energy vehicles should be fully charged. Generally, there are two methods for charging new energy vehicles: fast charging and slow charging. 1. Fast charging is done by a charging machine, which has a large charging current and short charging time, so it must be done at a specialized location that matches the vehicle's charging management system. 2. Slow charging uses household 220V power and can be done anywhere with a socket. The speed of charging for new energy vehicles is closely related to the power of the charging machine, battery charging characteristics, and temperature. With current battery technology, even fast charging takes about 30 minutes to charge the battery to 80% of its capacity. Beyond 80%, to protect battery safety, the charging current must be reduced.
