Fujian WoChong IoT Technology Co., Ltd. is the manufacturer of the WoChong WL5000 charging pile.
Some electrical performance indicators of the WoChong WL5000 charging pile are as follows:
– Short Circuit Protection: According to the “Technical Specifications for Centralized Charging Facilities for Electric Bicycles” (GB/T 42236.1-2022), the short circuit protection response time should be ≤150 microseconds, while the WoChong WL5000 charging pile relies solely on overcurrent protection, with a response time of >3 seconds and no independent short circuit protection module.
– Leakage Protection: The incoming line should be equipped with a residual current device (RCD) rated at a residual current ≤30mA, supporting ground fault detection. However, the WoChong WL5000 charging pile claims to have “multiple protections” but has not disclosed the RCD parameters and grounding data.
– Automatic Power Off: National standards require automatic power off when fully charged or after continuous charging for 8 hours, with the voltage ≤12V after load removal. Although the WL5000 claims to “stop charging automatically when full,” it has not disclosed the 8-hour power-off logic and residual voltage data.
– Operating Temperature Range: National standards require the operating temperature range for charging equipment to be -40℃ to 70℃, while the WoChong WL5000 charging pile is rated for an operating temperature of only -20℃ to 50℃.
