Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, specifically to a new energy power battery charge and discharge tester. Background Technology

[0002] The new energy power battery charge and discharge tester is a key piece of equipment for testing core components of new energy vehicles. It is mainly used to test and evaluate parameters such as charge and discharge performance, safety, and cycle life of power batteries such as lithium-ion batteries and solid-state batteries.

[0003] Existing new energy power battery charge and discharge testers typically employ a working mode combining fixed power modules and resistive loads. They perform single-channel or limited multi-channel performance tests on batteries by manually or via software setting charge and discharge parameters. Their energy recovery systems largely rely on traditional resistive loads to consume electrical energy, resulting in low energy utilization and the need for additional heat dissipation devices. The data acquisition and control modules have low integration, relying on external sensors and independent software for data processing. Safety protection functions mainly rely on relays and temperature switches to achieve basic overvoltage and overcurrent protection. Overall automation and testing efficiency need to be improved.

[0004] However, existing battery charge-discharge testing machines generally suffer from insufficient model compatibility and lack of environmental simulation capabilities. On the one hand, the power modules, battery interfaces, and testing procedures of these devices are mostly designed for single-model batteries. When testing batteries of different specifications, hardware components need to be manually replaced, which is time-consuming, labor-intensive, and prone to interface compatibility failures. On the other hand, existing equipment lacks a temperature environment control module, making it impossible to conduct charge-discharge tests on batteries in complex environments such as high and low temperatures and constant temperatures. This makes it difficult to simulate the actual operating conditions of new energy vehicles under different climatic conditions or extreme operating conditions, resulting in test results that cannot fully reflect the performance and safety of batteries in real-world usage scenarios, thus restricting the accuracy of battery research and development and application. Utility Model Content

[0005] The purpose of this utility model is to provide a charging and discharging testing machine for new energy power batteries, so as to solve the problems in the existing technology.

[0006] The power modules, battery interfaces, and testing procedures of the equipment are mostly designed for a single battery model. When testing batteries of different specifications, it is necessary to manually replace the hardware components.

[0007] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0008] A new energy power battery charge / discharge testing machine includes a cold / hot testing machine; a conveyor belt is provided on the side of the cold / hot testing machine; a battery body is provided inside the cold / hot testing machine; an electric sliding door is slidably connected to the side of the cold / hot testing machine; an electric slide rail is fixedly connected inside the cold / hot testing machine; a placement rack is slidably connected to the electric slide rail; multiple sets of connecting plugs are provided at the bottom of the placement rack; a power connector is fixedly connected to the side of the battery body, and the power connector matches the connecting plugs; a connection unit is provided inside the cold / hot testing machine.

[0009] As a further embodiment of this utility model: the connecting unit includes a first cylinder; the first cylinder is fixedly connected to the inner wall of the hot and cold testing machine; a second cylinder is fixedly connected to the side end of the first cylinder; an electric clamp is fixedly connected to the bottom end of the second cylinder; the electric clamp is located above the connecting plug.

[0010] As a further embodiment of this utility model: an electric push rod is fixedly connected to the inner wall of the thermal testing machine; a push plate is fixedly connected to the side end of the electric push rod, and the push plate is located on one side of the battery body.

[0011] As a further embodiment of this utility model: a second electric push rod is fixedly connected to the side end of the conveyor belt; an electric suction cup is fixedly connected to the side end of the second electric push rod, and the electric suction cup is located on the side close to the battery body.

[0012] The beneficial effects of this utility model are as follows: By setting up multiple types of connector plugs in the hot and cold testing machine, it is possible to quickly adapt and automatically test different specifications of batteries without the need for manual hardware replacement. It can directly complete charge and discharge tests under different temperature environments in the temperature-controlled chamber, realistically simulating the operating state of batteries under complex working conditions. This fills the technical gap that existing equipment cannot take into account the adaptation of multiple models and temperature environment testing, significantly reduces testing costs and operating difficulty, and provides a more comprehensive and efficient technical solution for battery performance evaluation and research and development.
