Charging tray for electric vehicle driving battery

Abstract

The present invention discloses a charging tray for an electric vehicle driving battery. The charging tray comprises a box body having a rectangular structure, wherein the upper surface of the box body is open, the interior of the box body is divided into four battery placement areas by two separation plates, steps are arranged in the battery placement areas on both sides of one of the separation plates and are positioned close to the separation plate, the steps of each battery placement area are respectively provided with two pairs of battery charging interfaces, each pair of the battery charging interfaces are used for inserted connection of a battery, connection conduction wires corresponding to the charging interfaces are integrally converged along the channel in the tray, and are connected to a total connector on the bottom portion of the tray in series or in parallel, and the total connector is positioned at the geometric center of the lower surface of the tray. According to the present invention, all the batteries on the same vehicle of the present invention can be simultaneously charged, used and replaced, such that the consistency of all the batteries on the same vehicle can be ensured so as to prolong the service life of the battery and improve the performance.

Description

technical field [0001] The invention relates to the improvement of the supporting technology of electric vehicles, in particular to a charging tray for driving batteries of electric vehicles, which belongs to the technical field of electric vehicle charging. Background technique [0002] Due to the cleanliness and environmental protection, low cost of use, and the continuous development of supporting technologies, in recent years, the acceptance of electric vehicles in the market has continued to increase, and the proportion has also continued to increase. The core and difficulty of electric vehicles lies in the driving battery, and the cost of the battery basically accounts for about half of the total cost of the vehicle. Moreover, the main problems in the subsequent use of electric vehicles, such as insufficient mileage, weak power, relatively high maintenance costs, and short battery life, are all directly related to the battery. The most important thing in the daily use...

AI Technical Summary

Problems solved by technology

Otherwise, the performance of different batteries is different, and the battery with poor performance will drag down other batteries as a whole, and the performance of the battery with good performance will drop quickly.

If each battery is charged separately, the voltage difference between the batteries may increase after charging, and the number of cycles of the batteries installed in the same vehicle may also be inconsistent during battery replacement, which is not conducive to the extension of battery life.
