Battery replacing method, battery replacing station and battery replacing cabinet

Abstract

The invention relates to the field of electric vehicle charging and battery replacing, in particular to an electric vehicle battery replacing method, a battery replacing station and a battery replacing cabinet. The electric vehicle in the battery replacing mode is a demander and a supplier; the battery replacing station is a station where a supply party and a demand party exchange power in a powerexchange mode, and the supply party and the demand party exchange power and exchange power through the interchange power station. The electric energy is transferred from a supplier to a demander in the following turnover mode with a battery as a carrier: the electric energy of a power supply network supplements energy for a spent battery of the supplier through charging equipment to form a fully-charged battery; a supplier arrives at an interchange power station to exchange power; a fully-charged battery and a spent battery are exchanged; a demander arrives at an interchange power station toexchange power, a spent power battery is exchanged with a full power battery; and the supplier replaces the spent battery and then supplies energy to the charging equipment. The method has the beneficial effects that the investment of charging equipment and the capacity-increasing transformation cost of a power grid of a charging and replacing station in the prior art are reduced through interchanging electricity between electric vehicles; and the quantity of stock batteries in the charging and replacing power station and the occupied funds are reduced.

Description

technical field [0001] The invention relates to the field of battery charging and swapping for electric vehicles, in particular to a battery swapping method for electric cars, a swapping power station, and a swapping cabinet. Background technique [0002] In order to reduce the charging time of electric vehicles, the technology of replacing batteries to supplement electric energy has begun to be applied and promoted. The existing battery swap technology operation mode, the battery swap mode rides an electric car, and the battery swap mode electric vehicle usually adopts the vehicle-electricity separation mode. The car owner rents the battery from the battery operator, and when the battery is exhausted, it goes to the charging station to replace the battery. The way to replenish energy, the battery is circulated and shared between electric vehicles. [0003] In the existing battery replacement method, when the battery of the electric vehicle is exhausted, the user-end APP (i...

Problems solved by technology

[0006] The purpose of the present invention is to provide a battery turnover method, which mainly realizes the transfer of electric energy from the supplier to the demander through the exchange of electricity between electric vehicles in the battery exchange mode, so as to reduce the investment in the storage battery of the charging station and the charging equipment in the station, and solve the current problem. The construction cost of charging and swapping stations with technology is high, the investment in setting up charging and swapping network points is large, and the network points are sparse
