[0003] In the prior art, the discharge tester tests the fixed state of the battery, that is, the battery is placed on a fixed workbench. However, during the use of the battery, it is possible to be in any state, such as in a new battery. Under the rotating condition of the energy vehicle battery, the current equipment cannot detect its discharge. We are not sure whether the battery discharge will be affected under such a rotating condition, so we need to design a device. Can detect the discharge state of the battery while it is rotating

The invention discloses a discharge tester for centrifugal acceleration of a new energy automobile battery, and solves the problem that a battery discharge tester in the prior art cannot test discharge filling of the battery in a centrifugal acceleration state. The discharge tester for centrifugal acceleration of the new energy automobile battery comprises a transmission shaft, a first acceleration disc, a second acceleration disc, a detection device, a current conduction device and a speed change device, the two acceleration discs are arranged on the transmission shaft, and meanwhile the speed change device is arranged to provide different rotation speeds for the transmission shaft; two battery fixing devices are arranged on each acceleration disc and used for installing a battery, a current conduction device and a detection device are arranged in the transmission shaft, the current of the battery can be conducted into the detection device under the condition of centrifugal acceleration of the battery, the detection device comprises an electrified wire set and a force sensor, the electrified wire set is electrified to generate ampere force, and then the ampere force is conducted out through the force sensor, and the discharge state of the battery under a centrifugal acceleration condition is indirectly measured.
Description
technical field [0001] The invention relates to the technical field of new energy vehicle batteries, in particular to a discharge tester for centrifugal acceleration of new energy vehicle batteries. Background technique [0002] A battery refers to an electrochemical component that stores chemical energy and releases electrical energy when necessary. It is widely used in all walks of life in industry, agriculture and national economic development, and has made great progress in the field of new energy vehicle technology. , and the performance of the battery affects the performance of the new energy vehicle to a large extent, and in order to accurately grasp the state of the battery during use, it is necessary to detect its discharge behavior through a discharge tester. [0003] In the prior art, the discharge tester tests the fixed state of the battery, that is, the battery is placed on a fixed workbench. However, during the use of the battery, it is possible to be in any st...
