New energy vehicle quick-replacement type general power battery

Abstract

The invention discloses a new energy vehicle quick-replacement type general power battery. A battery body is provided with one or more of quick-replacement interfaces, an interface concave structure,an independent liquid temperature control loop and multi-group interface structures, the battery body is provided with a concave field, and the quick-replacement interfaces are located in the concavefield to leave space for arranging a corresponding connection structure on a vehicle; the independent liquid temperature control loop is arranged on the battery body to meet needs of power battery temperature control, and at the same time the problem that the power battery is not suitable for building a liquid temperature control system with the vehicle under the condition of exchanging is solved;the quick-replacement interfaces are arranged at least two surfaces of the battery body, the vehicle can be loaded in different directions, and the battery body combined with battery form can be usedfor new energy vehicles with different installation space conditions; and so battery generality is strong, a system is composed of no more than 8 main types of quick-replacement general power batteries, the purpose of most of new energy vehicle models selecting and electric changing can be achieved, and the combination of the battery and charging meets the convenience requirement of the new energy vehicles to electric energy supplement.

Description

technical field [0001] The invention relates to the field of power batteries for new energy vehicles, in particular to a quick-change universal power battery for new energy vehicles. Background technique [0002] We used to use fuel-based vehicles for a long time, and there were air pollution problems caused by exhaust emissions and the problem that the source of fuel was basically not renewable. As the amount of use increased, the problem became more and more serious. [0003] The application of various new energy vehicles can effectively improve the above problems. Most of the existing new energy vehicles are driven by electricity, and the electric energy comes from other vehicle-mounted energy sources or external charging. Fuel oil is still used for other vehicle energy sources, because the use of new power devices reduces its consumption and exhaust emissions, while other types use green energy as a source of power generation. New energy vehicles that use other energy ...

But there are also disadvantages: slow charging takes a long time, and therefore public charging places are easy to be occupied and need to wait first; fast charging (using high-power charging piles, but the current charging speed is still significantly slower than the refueling speed of fuel vehicles) due to the large power has a great impact on the power grid. The configuration requirements are high, and it is easy to cause the peak-valley imbalance of the power grid, so the number of configurations is limited

In this case, if the battery exchange points are widely distributed, it will lack practicability and economy, and the few distribution points cannot meet the battery exchange needs of the corresponding models. Therefore, the current battery exchange is only suitable for centralized distribution (battery exchange points) and is mainly used in regional areas. New energy vehicles for permanent use, such as taxis, online car-hailing, buses, etc., cannot be widely used
