Thermal shock test requirements
The sample was heated in a natural convection or forced convection oven. The oven temperature was ramped up to 130 °C ± 2 °C at a rate of 5 ± 2 ° C / min, and was stopped after 10 min.
The test chamber is heated at a temperature rise rate of (5 ± 2) ° C / min, and the temperature is constant after the temperature in the chamber reaches 130 ° C ± 2 ° C for 30 min.
The fully charged battery is placed in a natural convection or circulating air convection oven. When the ambient temperature is 20 °C ± 5 °C, the oven temperature is increased to 5 °C / min ± 2 ° C / min to a temperature of 130 ° Hold at °C ± 2 ° C for 30 min.
