Many electric forklift operators occasionally encounter the code E-25 prompt on the vehicle display panel during daily high-frequency operation, and many non-professional on-site staff may have unnecessary misjudgment of the fault level. As a professional operator that specializes in BYD electric forklifts, Jianshu New Energy has accumulated rich front-line operation and maintenance experience in fault handling, and our professional service team will share standardized, practical operation suggestions for this fault code.
First of all, it is necessary to clarify that the forklift code E-25 is mostly a pre-warning signal triggered by the temperature perception module of the power system, and the common triggering scenarios include continuous heavy-load operation for more than 4 hours, outdoor operation in high temperature and poor ventilation conditions in summer, or long-time continuous climbing operation, which does not mean irreversible damage to the core components of the vehicle.
Our service team recommends that users take the first step of disposal immediately after seeing this fault prompt: park the vehicle on a flat and ventilated area, turn off the auxiliary power switch, do not force restart the vehicle immediately, keep it in static state for 15 to 20 minutes to let the power-related components cool down naturally. After that, restart the vehicle to check whether the fault code is automatically cleared. Statistics from our service cases show that more than 60% of such faults can be eliminated through this operation, and the vehicle can return to normal operation.
If the fault code still exists after static cooling and restart, the service team recommends the second step of operation: do not disassemble the circuit components of the vehicle without professional qualification, first check whether there are excessive debris such as cargo packaging scraps and industrial dust accumulated in the vehicle heat dissipation grille area, after cleaning up the foreign matters, let the vehicle stand for another 10 minutes and try to restart. This step can cover most of the remaining fault scenarios that are not caused by hardware damage.
If the above two operations do not eliminate the fault code, the standard suggestion of our service team is to stop using the vehicle immediately, contact our official operation and maintenance team in time, and let the certified professional technicians complete professional operations such as temperature sensor calibration and circuit connection status inspection, so as to avoid additional component damage risks caused by non-professional operation. In daily use, regular cleaning of the heat dissipation system and reasonable arrangement of intermission for heavy load operation can effectively reduce the trigger probability of E-25 fault code.
