Overview

1、 Requirement: The temperature of the battery or battery pack to be tested must be stabilized to achieve a shell temperature of 55 ° C; 2 ℃, then subject the battery or $r $n battery pack to a temperature of 55 ° C; Under short-circuit conditions with a total external resistance of less than 0.1 ohms at 2 ℃. This short-circuit condition should occur when the temperature of the battery or battery pack casing returns to 55 degrees Celsius; Continue for at least 1 hour after 2 ℃. The battery or battery pack must be observed for another 6 hours before the test can be completed.

1requirementsThe temperature of the battery or battery pack to be tested must be stabilized so that the temperature of its outer shell reaches55±2℃, then use the battery or

The battery pack is55±2Under ℃, the total external resistance is less than0.1Ohmic short-circuit condition. This short-circuit condition should occur in the battery or battery pack

The shell temperature returns to55±2Continue at least after ℃1hour The battery or battery pack must be observed again6The experiment ended in hours.

2、 Purpose of the experiment:The remote control high current short-circuit device is designed to meet the requirements of various battery short-circuit test standards. According to the standard requirements, the short-circuit device must comply with the internal resistance range far less than100mΩ, in order to obtain the maximum short-circuit current required for the test.
