Description

UL 1642 Test Standard Should Be Perform (EV Electric Vehicle Battery)

Standard for safety Lithium Batteries

Heating Test

A battery is to be heated in a gravity convection or circulating air oven with an initial temperature of 20 +5'c (68 + 9'F). The temperature of 130 + 2'c (266 + 3.6F) and remain for 10 min. The sample shall return to room temperature (20 + 5'c) and then be examined. For batteries specified for temperatures above 100'c (212'F), The conditioning temperature shall be increased from 130 + 2'c (266 + 3.6'F), to 30 + 2'c (86 + 3.6'F) above the manufacturers maximum specified temperature. For the battery of lithium metal chemistry, the conditioning temperature shall be increased to maximum of 170 + 2'c (338 +3.6'F).

Temperature Cycling Test

The batteries are to be placed in a test chamber and subjected to the following cycles:

a) Raising the chamber-temperature to 70 + 3'c (158 + 5'F) within 30 min and maintaining this temperature for 4 h.
b) Reducing the chamber-temperature to 20 + 3'c (68 + 5'F) within 30 min and maitaining this temperature for 2 h
c) Reducing the chamber temperature to minus 40 + 3'c (minus 40 + 5'F) within 30 min and maintaining this temperature for 4 h.
d) Raising the chamber temperature to 20 + 3'c (68 + 5'F) within 30 min
e) Repeating the sequence for a futher 9 cycles.
f) After the 10th cycle, storing the batteries for a minimum of 24h, at a temperature of 20 + 5'c (68 + 9'F) prior to examination.
