5.1 Equipment Test Items
Product model JH400V300A-EOL Purpose Used for testing semi-finished and finished battery packs below 400 V. Basic Test Items
① Let stand ② Battery activation (via charging, discharging, and disconnecting the load, etc.) ③ Open-circuit voltage 1, open-circuit voltage 2 (can measure the charging port voltage) ④ AC internal resistance ⑤ DC internal resistance ⑥ Discharge testing (assesses the battery pack’s continuous load‑carrying capability and checks the voltage drop ΔV during sustained discharge) ⑦ Discharge Overcurrent Test (testing the battery pack’s discharge overcurrent protection function, supporting secondary-level protection testing) ⑧ Charging test (continuous charging function of the battery pack, to verify whether charging is operating normally) ⑨ Overcurrent Charging Test (testing the battery pack’s overcurrent protection function, supporting secondary-level protection testing) ⑩ Resistance R1, R2 testing (including ID and NTC resistor tests) ⑪ Short‑circuit test (measures the battery’s cut‑off protection time for a positive–negative short circuit, in the µs range; supports disabling voltage detection and enabling recovery voltage detection) ⑫ Insulation resistance test: Measure the insulation resistance between the battery pack’s positive terminal and any exposed conductive external parts, as well as between the battery pack’s negative terminal and any exposed conductive external parts, under rated DC voltage conditions. ⑬ Withstand Voltage Test: A corresponding voltage shall be applied between the positive terminal of the battery pack and any exposed conductive parts on the exterior, as well as between the negative terminal of the battery pack and any exposed conductive parts on the exterior; no breakdown or flashover shall occur. For all batteries except storage batteries…
An appropriate voltage shall be applied between the external interface terminals—other than the positive and negative terminals—and any externally exposed conductive parts.
Under pressure, no breakdown or flashover shall occur.
Equipment protection function Software protection feature: Power-loss data protection Hardware protection: power‑off protection, short‑circuit protection, reverse battery connection protection, and incorrect wiring protection. 5.2 Equipment Technical Parameters
