Test Equipment & Setup
| Item | Detail |
|---|---|
| Test Equipment | Thermal Shock Chamber / Power Meter (冷热冲击箱 / 功率计) |
| Room Temperature | 23 °C |
| Room Humidity | 60 % |
| Soak Duration per Condition | 2 hours |
| Charging condition range | 0 °C to 45 °C (normal charging: 0 °C – 41 °C) |
| Protection condition range | −22 °C (low-temp) and 62 °C (high-temp) |
| Discharge condition range | −17 °C to 58 °C |
Test Procedure
- Pre-test: Confirm samples are fully functional at room temperature (23 °C, 60 % RH) before beginning temperature conditioning.
- Charging conditions (0 °C – 45 °C): Place samples in the thermal shock chamber set to the target temperature; stabilize for 2 hours; then connect charger and observe charging display and current readout.
- Discharge conditions (−17 °C – 58 °C): Set chamber to target temperature; stabilize samples for 2 hours; power on and verify normal inflation/discharge operation.
- Protection conditions (−22 °C and 62 °C): Set chamber to −22 °C or 62 °C; stabilize samples for 2 hours; power on and record any protection error codes displayed.
- Post-test: Return samples to room temperature; inspect for physical damage, display anomalies, or functional degradation; record all observations.
- Acceptance: Samples must operate normally within specified temperature bands; protection codes (E13 / E14) must activate correctly at the defined thresholds.
Test Data & Results
| Sample ID | Test Condition | Observations |
|---|---|---|
| X6-6# / X6-7# | High-Temp 45 °C Charging Test | 1. After 2 hours at 45 °C: display showed normal charging, but no actual charging occurred — no current displayed. 2. After 2 hours at 41 °C: display showed normal charging and current reading was normal. |
| X6-6# / X6-7# | Low-Temp 0 °C Charging Test | 1. After 2 hours at 0 °C: display showed normal charging and current reading was normal. |
| X6-6# / X6-7# | High-Temp 58 °C Discharge Test | 1. After 2 hours at 58 °C: powered on normally and discharged (inflated) without issue. |
| X6-6# / X6-7# | Low-Temp −17 °C Discharge Test | 1. After 2 hours at −17 °C: powered on normally and discharged (inflated) without issue. |
| X6-6# / X6-7# | High-Temp 62 °C Protection Test | 1. After 2 hours at 62 °C: powered on and displayed E14 (High-Temperature Protection activated). |
| X6-6# / X6-7# | Low-Temp −22 °C Protection Test | 1. After 2 hours at −22 °C: powered on and displayed E13 (Low-Temperature Protection activated). |
Observations summary: At 45 °C the BMS correctly inhibits charging current while the display remains active, confirming high-temperature charge protection is functional. At 41 °C charging resumes normally, establishing the effective upper charging threshold. Discharge operation is confirmed across the full −17 °C to 58 °C range. Protection codes E14 and E13 trigger correctly at 62 °C and −22 °C respectively, confirming thermal protection logic is intact.

Frequently Asked Questions
What is the normal operating temperature range for the ETENWOLF X6PRO tire inflator?
The X6PRO operates normally for discharge (inflation) between −17 °C and 58 °C. Charging is supported between 0 °C and 41 °C. Outside these ranges, the BMS engages protection modes rather than allowing potentially damaging operation.
Why does the X6PRO display show charging at 45 °C but no current flows?
At 45 °C the battery management system (BMS) inhibits actual charging current to protect the cell from high-temperature stress, even though the display indicates a charging state. Normal charging resumes at 41 °C and below, as confirmed during testing.
What do error codes E13 and E14 mean on the X6PRO?
E13 indicates Low-Temperature Protection — triggered when the unit is powered on after stabilizing at −22 °C or below. E14 indicates High-Temperature Protection — triggered when the unit is powered on after stabilizing at 62 °C or above. Both codes prevent operation until the unit returns to a safe temperature range.
What test standard was used for the X6PRO operating temperature test?
The test was conducted against ETENWOLF’s Internal Control Standard. Samples were conditioned for 2 hours at each target temperature in a thermal shock chamber, then evaluated for charging behavior, discharge operation, and thermal protection code activation.
