Electric vehicle battery replacement device and battery replacement system

Abstract

The invention relates to a battery replacement device applicable to an electric vehicle, which comprises a battery box turntable group, a charging rack battery taking and placing device and an electric vehicle battery taking and placing device, wherein the battery box turntable group comprises a plurality of battery box turntables arranged in a line, and the battery box turntables can rotate with a certain angle around axes per se; the charging rack battery taking and placing device is arranged between the battery box turntable group and a charging rack; and the electric vehicle battery taking and placing device is arranged between the electric vehicle and the battery box turntable group. The invention also relates to a battery replacement system with the battery replacement device. In the battery replacement device, two types of battery taking and placing devices are used to be matched with the turntables to ensure that the battery box replacement of the electric vehicle becomes smoother. The entire battery replacement process is smooth and short in time. Because the efficiency of battery replacement is increased, more battery replacements can be completed within unit time, the battery replacement period is shorter, so that a charger can charge completely, and the utilization rate is higher.

Description

technical field [0001] The invention relates to the field of energy technology utilization, in particular to a battery replacement device and a battery replacement system suitable for electric passenger vehicles. Background technique [0002] As an important part of the new energy strategy and smart grid, and one of the strategic emerging industries identified by the State Council, electric vehicles will gradually become the focus of the development of China's automobile industry and energy industry. In the process of commercialization and industrialization of electric vehicles, especially electric passenger vehicles, how to supply energy to electric passenger vehicles is an extremely important factor. A perfect energy supply system will provide a very important support. [0003] The number of battery boxes in electric passenger vehicles is small, most of which are 4 sets, but due to the limited space of electric passenger vehicles, the installation positions of batteries o...
