How to Solve the Power Leakage Issue in Roewe e550?

To determine whether the battery itself has internal leakage causing insufficient voltage. With the increase of automotive electrical equipment and battery capacity, the dark current will also increase simultaneously. If the dark current reading exceeds 90mA or even reaches several hundred mA, it indicates leakage in the anti-theft device circuit or other circuits in the vehicle.

I just bought a Roewe e550 not long ago and encountered a power leakage issue, which is really annoying. Don’t panic yet—for hybrid cars, power leakage is mostly caused by battery aging or charging system problems. Pay attention to signs like sudden dimming of headlights or warning lights on the dashboard; those are red flags. I did some DIY checks: first, see if the battery terminals are loose, then use a multimeter to measure the voltage—it should be around 12 volts; if it’s lower, the battery might need replacement. Next, check the fuse box to see if any fuses are blown. Also, inspect the charging port to ensure it’s not corroded or water-damaged. Remember to remove the ignition key when repairing to avoid electric shock. If DIY doesn’t work, I’d recommend visiting a 4S shop—their professional diagnostic tools can pinpoint the issue quickly. Don’t skimp on safety; it’s worth the cost. Regular maintenance can prevent this, like cleaning dust from the car’s electrical circuits every six months.

As a veteran driver with 30 years of experience, I've also encountered the issue of power leakage in the Roewe e550. It needs to be addressed at the root. The leakage problem mainly stems from the electrical system, possibly due to worn wiring or control module failure. Don't underestimate it - the battery can drain completely within half a day after parking, which is quite dangerous. When I discovered it, I first tested the battery capacity to confirm it wasn't just simple aging. Then I inspected the vehicle's wiring, especially the cables in the engine compartment, to avoid short circuits and corrosion. I recommend using a diagnostic tool to connect to the vehicle's computer and scan for error codes, which can quickly locate the source of the problem. If you really can't find it, rely on professional repair shops - they can perform more comprehensive tests by dismantling parts, rather than risking improper DIY repairs. Remember, timely replacement of old components, such as regular inspection of charging units, can extend the vehicle's lifespan.

After discovering a leakage in the Roewe e550, I followed the steps to address it. First, check the battery status to see if the voltage is below 11 volts; then inspect whether the fuse or relay is burnt. Don’t forget the charging port—loose connections or contamination can cause leakage. A simple solution is to clean the circuit connectors and try replacing the battery. If that doesn’t work, seek professional diagnosis at an authorized service center with proper tools—don’t delay. Prevention is key: keep the interior dry and avoid parking in damp areas.
