A Method for Eliminating Lateral Force of a Floating Platform for Power Exchange

Abstract

The invention provides a method for eliminating lateral force of a floating platform for battery replacement. The method comprises the steps: determining the state, specifically, the relative positions of the floating platform, a battery assembly and a vehicle bottom battery fixing structure are acquired to determine whether a battery is in a mounted state or a dismounted state; and locking the floating, specifically, when the battery is in the mounted state or the dismounted state, a clamping mechanism connected to a rigid substrate of a battery replacement platform locks the floating platform to enable the floating platform not to float but to form a rigid body with the clamping mechanism, so that the lateral force of the floating platform recovering the balance position is eliminated. The method for eliminating the lateral force of the floating platform for battery replacement has the advantages of ingenious conception and strict logic, the elimination of the lateral force of the floating platform is achieved through the automatic judgment of the state of the battery, unnecessary collision of battery components is effectively avoided, the requirement of quick battery replacementof a new energy vehicle is met, and the method is convenient to apply and popularize.

Description

technical field [0001] The invention belongs to the field of rapid battery replacement, and in particular relates to a lateral force elimination method for a floating platform used for battery replacement. Background technique [0002] With the increasing use of various types of new energy vehicles such as electric vehicles and hybrid vehicles, technologies related to quick battery replacement have become more and more people's attention and research topics. [0003] In the process of battery replacement through the battery replacement system, the battery pack at the bottom needs to be replaced accurately, and the position of the vehicle or the battery replacement platform needs to be adjusted. However, when positioning and adjusting the vehicle or the battery replacement platform, it is inevitable. There will still be errors. In order to make the positioning and alignment actions go smoothly, the target object needs to be able to float freely, that is, the contact surface b...

[0003] In the process of battery replacement through the battery replacement system, the battery pack at the bottom needs to be replaced accurately, and the position of the vehicle or the battery replacement platform needs to be adjusted. However, when positioning and adjusting the vehicle or the battery replacement platform, it is inevitable. There will still be errors. In order to make the positioning and alignment actions go smoothly, the target object needs to be able to float freely, that is, the contact surface between the power exchange platform and the battery pack and the support surface in contact with the vehicle need to be floatable; but in the horizontal direction During the floating process, it is easy to deviate from the middle position and generate a lateral force back to the center, making the battery replacement process unstable, resulting in unnecessary bumps during installation or disassembly, and affecting battery life
