Safe and rapid battery replacement battery and matched electric chassis thereof

Abstract

The invention relates to a safe and rapid battery replacement battery comprising a battery shell, a battery pack is arranged in the battery shell, driving wheels are arranged on the two sides of the bottom of the battery shell respectively and driven by a driving motor assembly, a battery connector is arranged on the front side of the battery shell, a guiding sensor is arranged outside the battery shell, and a battery brain is arranged in the battery shell. The battery brain comprises an AGV navigation controller and a communication module, the power battery pack is electrically connected with the battery connector and the battery brain, the battery brain is electrically connected with the driving motor assembly, and the communication module achieves information exchange between the battery brain and a ground control station. The battery essentially depends on a low-cost plane battery swap station, the battery swap station is built everywhere, battery swap can be performed at any horizontal plane at any time, a small number of intelligent batteries are used for meeting the use of a large number of vehicles, high-capacity intelligent batteries are temporarily installed during long-distance vehicle use, the high-capacity intelligent batteries are returned to the battery swap station in time after use, and the station building cost is very low.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a safe and fast battery replacement and its matching electric chassis. Background technique [0002] In response to problems such as mileage anxiety encountered by electric vehicles, various automobile manufacturers have come up with their own countermeasures. Such as Tesla's super fast charging plan. BYD's blade battery plan improves battery safety and volumetric energy density. Weilai's three-minute battery swap plan is comparable to the speed of refueling. Xiaopeng Motors’ half-price car purchase and battery lease plan, the starting price is a bit expensive, at least 1,599 yuan per month, and if it is reduced to half, it will be as competitive as gasoline cars, and a large number of people will agree. [0003] At present, the state has reduced subsidies for electric vehicles, and the state has increased the construction of charging piles. [0004] Charging is con...

AI Technical Summary

Problems solved by technology

[0008] At present, various electric vehicle manufacturers prepare their own power batteries. There are BAIC models, Weilai models, heavy truck models, Changan models, and Geely models. None of the batteries are universal.

In the existing battery replacement technology, due to technical defects, the cost of building a station is very high, and the battery replacement speed is only a few minutes, which is not fast enough and the efficiency is low, resulting in low social acceptance.
