What are the reasons for the battery failure indication in BAIC New Energy vehicles?

[StephenDella]

BAIC New Energy battery warning light may illuminate due to the following reasons: 1. Battery aging issues: The typical battery lifespan is approximately 3 years. Prolonged use may lead to internal sulfation, insufficient battery capacity causing severe power loss, internal battery grid breakage, or electrode short circuits. Battery replacement is recommended. 2. Loose battery connections or charging circuit problems: Check whether the positive and negative terminal connections are loose, and inspect the charging circuit for aging or short circuits. 3. Generator malfunction: Issues such as damaged voltage regulators, burnt-out rectifiers, carbon brushes worn to their limit, or short circuits in stator/rotor coils may prevent the generator from producing electricity. Generator replacement is necessary. 4. Generator belt problems: A loose belt may cause insufficient rotation speed. Generator belts should generally be replaced every 100,000 kilometers or 3 years, requiring timely adjustment or replacement.

I've been driving new energy vehicles for over a decade and have considerable experience with battery failures. When a BAIC新能源 vehicle displays a battery fault, the most common issue is a Battery Management System (BMS) malfunction - that's the computer module monitoring battery temperature and voltage going wrong. Another frequent problem is individual battery cell failure, where one small battery in the pack dies and triggers the whole system alarm. Poor contact is also common, especially when connectors oxidize after rain causing short circuits. Last time my car showed a fault, it turned out to be caused by voltage instability during charging. I strongly advise against DIY repairs - take it directly to a service center to scan for trouble codes with their professional diagnostic equipment. Their specialized tools can pinpoint the exact issue, and tampering with high-voltage batteries without proper knowledge is extremely dangerous.

I used to drive a BAIC electric van for deliveries when suddenly the dashboard flashed a battery malfunction while driving. The mechanic said it might be due to a cell in the battery pack reaching the end of its lifespan, causing voltage drop and instability, or possibly an issue with the cooling system. During summer highway driving, if the battery overheats, the system will enforce protective measures. I remember that time it turned out the cooling fan was clogged with leaves, and it worked fine after cleaning. It's recommended to pay attention to battery maintenance—don’t wait until the battery is completely drained to recharge; charge it when it drops to 20% to maintain stable power levels. If the vehicle isn’t used for long periods, remember to perform regular charge-discharge cycles, as lithium batteries are most vulnerable to prolonged power depletion.

I think the battery fault alarm of BAIC New Energy should be taken seriously. It might be due to overcharging or over-discharging during charging, which damages the battery. Frequent fast charging can also reduce its lifespan. Last year, my car showed a fault, and the inspection revealed it was caused by loose wiring connectors due to vibrations on bumpy roads. There's also the issue of battery pack aging itself; after five or six years of use, the reduced range can easily trigger false alarms. The key is to promptly go to the service station to read the fault codes and not delay. If the battery is under warranty, the repair is free; if it's out of warranty, you might have to pay for it yourself, so handling it early saves money.
