Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy vehicles, in particular to a method for increasing the cruising range of new energy vehicles through a power generation device. BACKGROUND

[0002] At present, under the restriction of power battery materials and technology, new energy vehicles generally have large battery capacity and are good for short trips, but are not enough for long-distance cruising, and need to be stopped frequently for charging, which not only delays the journey but also is inconvenient. This is a problem that many car companies have not fundamentally solved and broken through, and that the majority of car owners cannot eliminate.

[0003] Some new energy vehicles on the market that use plug-in hybrid power generally have small battery capacity and need to rely on constant conversion between power batteries and fuel engines for long and short trips. At most, they can only travel more than 100 kilometers relying on power batteries, and then need to be converted into traditional fuel engines for travel, which is still mainly relying on traditional fuel engines. There is still a certain gap with the concept of pure electric vehicles, that is, relying solely on power batteries for travel, so there is an urgent need for a new solution to increase the cruising range of new energy vehicles.
