IP67 Sealed Steel Housing, Multi Waterproof LV Connectors, Reserved Diagnosis Port

This OE 2120015-TE810 battery low voltage control box adopts fully sealed thick steel shell with full-circle rubber sealing gaskets, reaching IP67 protection grade to block rainwater, road dust and mud from entering the internal circuit board, avoiding short circuit and signal interruption under complex outdoor transportation environments. It is equipped with multiple independent IP67 waterproof LV control connectors, separately transmitting each group of battery pack monitoring signals without mutual interference, ensuring accurate real-time feedback of cell voltage and temperature data to vehicle VCU. A dedicated debugging diagnosis port is reserved on the side, maintenance technicians can quickly read battery fault codes without disassembling the whole box, greatly shortening troubleshooting time. The integral mounting lugs with symmetrical CNC machined bolt holes completely copy Dongfeng new energy truck chassis installation size, realizing plug-and-play whole-unit replacement without cutting or modifying vehicle wiring harness.

Poor Sealing Water Short Circuit, Single Channel Signal Interference, No Independent Diagnosis Port

New energy truck three-electric system maintenance technicians often face battery safety hidden dangers caused by inferior aftermarket control boxes: thin plastic or poorly sealed metal housings easily seep rainwater, leading to internal circuit board short circuit and battery pack protection shutdown; single shared signal channel causes data interference, resulting in inaccurate temperature and voltage monitoring and triggering false power limitation; no reserved diagnosis port requires disassembly of the whole control box to read faults, wasting a lot of maintenance labor hours. This genuine DFCV OEM power battery low voltage control box completely eliminates these risks: full IP67 sealing prevents water & dust damage; multi-channel independent transmission avoids signal interference; dedicated diagnosis port simplifies fault detection, cutting new energy vehicle three-electric system overhaul frequency and sudden power failure accidents for Dongfeng new energy fleets.
