5.8 safety performance
project
The test method
request
Thermal
shock
Charging standard, and let sit 24 h, and then put the battery in hot
box, hot box temperature for the solution of (5 + 2 ℃) rose to 130
+ 2 ℃ / min rate and thermal insulation for 30 min
No fire, no explosion
charging
After charging standards, puts the battery with the thermocouple
in the fume hood, batteries and slide rheostat in series on a
constant current constant voltage source, the voltage of 4.8 V,
through to 3 c5a slide rheostat to adjust current, then the battery
charging with 3 c5a, testing process monitoring battery
temperature change, when the battery temperature down to about
10 ℃ lower than the peak, the end of the experiment.Testing is
not required in the process of current keep 3 c5a.
No fire, no explosion
A short
circuit
After charging standards, puts the battery with the thermocouple
in the fume hood, a short circuit is the cathode (line resistance is
not more than 100 m Ω ), test in the process of monitoring the
battery temperature change, when the battery temperature down
to about 10 ℃ lower than the peak, the end of the test.
Battery, no fire, no explosion
temperature shall not be
higher than outside 130℃
Note: the short circuit at ear fuse is a normal phenomenon
