Programmable analog heating apparatus used for battery thermal management test and control method for programmable analog heating apparatus

Abstract

The invention discloses a programmable analog heating apparatus used for a battery thermal management test and a control method for the programmable analog heating apparatus. The programmable analog heating apparatus comprises an upper computer and a plurality of single analog heating apparatuses; the upper computer is connected with each single analog heating apparatus through a communication bus; a battery database and a working condition database are stored in the upper computer; each single analog heating apparatus is provided with a distributed control sub board, a small-sized power module, a heating apparatus and a temperature collection module; the upper computer reads the battery database and the working condition database and obtains heating power data through calculation; then the upper computer transmits the heating power data to each single analog heating apparatus through the corresponding communication bus; the distributed control sub board in each single analog heating apparatus controls the small-sized power module to output corresponding voltage and current to the corresponding heating apparatus so as to control the corresponding heating apparatus to give out heat; the temperature collection module collects the temperature data of each single analog heating apparatus and transmits the data to the corresponding distributed type control sub board; and the distributed type control sub board transmits the temperature data to the upper computer through the corresponding communication bus.

Description

technical field [0001] The invention relates to a device and method for simulating battery heating and testing. Background technique [0002] Battery characteristics are significantly related to temperature. The ambient temperature directly affects the performance of the battery. If the temperature is too high or too low, or the temperature difference between the single cells is too large, it will affect the electrochemical reaction inside the battery, and then affect the performance, safety and service life of the battery pack. . For energy storage systems, an intelligent and efficient battery thermal management system is essential. [0003] Just because battery thermal management takes such an important responsibility, it is necessary to strictly test its temperature field characteristics during the development stage of the battery pack. test. [0004] The existing thermal management test technology solution is to directly load the real battery pack into the real energy...

Problems solved by technology

However, testing the battery thermal management system directly with a real battery pack is not only inconvenient and costly, but also poses serious safety hazards.

Directly using real battery packs to simulate various working conditions for detection will not only cause permanent capacity loss to the battery pack, but also have long charging and discharging times, unsuitable for long-term repeated cycle tests, difficulty in simulating fault states, and repeatability and Disadvantages such as poor controllability
