Ettaala erabula bbaatule ne alternator okulemererwa ng’ovuga: okuyiwa emigugu gy’amasannyalaze n’okuwona ekiro

Ennamba z’embeera ez’amangu zaawukana okusinziira ku nsi. Omuko guno gukozesa 911, ennamba ya Amerika ne Canada. Ensi endala nnyingi zikozesa 112, 999, oba ennamba endala. Funa ennamba y'ensi yo.

Akabonero akalaga okulabula akamyufu akalinga bbaatule bwe kaaka ku kibinja ky’ebikozesebwa mu mmotoka nga yingini ekola, ekizibu kumpi tekibangawo bbaatule ya vvuloti 12 eya asidi w’omusulo yennyini: kalaga nti alternator (oba omusipi oguvuga omusota) gukomye okukola amasannyalaze. Alternator bw’emala okulemererwa, mmotoka ekyuka mu kaseera ako okuva ku kyuma ky’amasannyalaze ekyeyimirizaawo okudda ku kubala bbaatule ya reserve eriko enkomerero. Buli mpiso y’amafuta ey’amasannyalaze, koyilo y’omuliro, kompyuta efugira yingini, ekifo we bateeka siteeringi ey’amasannyalaze, ne bbaatule y’amataala kati bifulumya amaanyi g’eddagala agaterekeddwa butereevu okuva mu bbaatule ya vvuloti 12 awatali kujjuzaamu.

Okusinziira ku oba emisana oba kiro, oba omusipi gwa serpentine nagwo guvuga ppampu y’amazzi ey’ebyuma, n’amangu ddereeva gy’aggyako ebikozesebwa by’amasannyalaze ebitali bikulu, mmotoka erimu alternator eremereddwa esobola okutambula wonna okuva ku eddakiika 2 (singa omusipi gwa ppampu y’amazzi gukutuse) okutuuka ku ddakiika 45 (mu kiseera ky’omusana ng’emigugu gyonna egy’amasannyalaze giyiiriddwa) nga vvulovumenti y’enkola tennagwa wansi 9.0 volts. Voltage bw’ekka okuyita ku threshold eyo, electric power steering efuuka freeze, dashboard gauges ziddugala, anti-lock brakes zigwa, era yingini n’eyimirira wakati mu kalippagano k’ebidduka nga zero ability to crank back over.

Kino kikole kati

  1. Kebera ekipima ebbugumu lya yingini ne kaweefube wa siteeringi amangu ddala: The instant the red battery icon (+ -) oba "Charging System Malfunction" alert ejja, tunuulira ekipima ebbugumu ly’amazzi agabuguma n’owulira oba siteeringi efuuse nzito mu bwangu. Ku yingini ezisinga obungi, omusipi gumu ogwa kapiira ogwa serpentine guwuuta alternator, ppampu y’amazzi ne ppampu ya hydraulic power steering wamu; singa omusipi ogwo gukutuka, yingini ejja kufumba n’efuuwa gaasi yaayo ey’omutwe mu sikonda 60 ku 120. Singa ekipima ebbugumu erinnya mangu oba siteeringi ekalubye mu bwangu, ssika ku kibegabega oggale yingini mangu.
  2. Shed all non-essential electrical loads within 10 seconds: Singa ebbugumu lya yingini liba lya bulijjo (ekitegeeza nti alternator yalemererwa munda ng’omusipi gukyali mu mbeera), gula obudde obusinga obunene bw’okuvuga ng’oggalawo buli mukozesa w’amasannyalaze alina ekiwuka: ggyako ddala ekyuma ekifuuwa empewo n’ekyuma ekifuuwa ebbugumu mu kabina, ggyako entebe ezibuguma, siteeringi ebuguma, n’ekyuma ekifulumya eddirisa ery’emabega (the single heaviest resistive electrical load in a car), ggyako screen ya radio/infotainment, ggyamu chargers z’amasimu ne inverters, era oggalewo amadirisa g’amasannyalaze kati nga bbaatule tennafa.
  3.

Every hybrid and electric vehicle contains two completely separate electrical architectures:

  • The High-Voltage (HV) Traction Pack (300V to 800V DC): Powers only the large electric propulsion motors and the high-voltage air conditioning compressor. For crash safety, the high-voltage battery pack is isolated inside a sealed metal vault by spring-loaded electromagnetic switches called High-Voltage Contactors (Relays) that require continuous 12-volt current to stay held closed.
  • The Low-Voltage Auxiliary System (12V Lead-Acid, AGM, or LiFePO4 Battery): Powers all safety-critical vehicle computers, the brake-by-wire booster, electric power steering, headlights, hazard flashers, door locks, and the 12-volt coils holding the high-voltage traction contactors closed.

Instead of a belt-driven mechanical alternator, hybrids and EVs recharge their 12-volt battery from the high-voltage pack using a solid-state electronic transformer called a DC-to-DC Converter. If the DC-to-DC converter fails (or if a 12-volt battery cell shorts internally), the 12-volt auxiliary system begins draining exactly like a gasoline car with a broken alternator, with one critical difference: in an EV or hybrid, once the 12-volt battery drops below 9.5 to 10.0 volts, the 12-volt magnetic coils holding the high-voltage contactors drop open, instantly disconnecting the main 400-volt drive motor and causing a sudden loss of propulsion and brake-by-wire boost.

Emergency protocol for a 12V charging warning in a hybrid or EV

  1. Pull off the highway even faster than in a gasoline car (within 5 to 10 minutes): Auxiliary 12-volt batteries installed in hybrids and EVs are physically much smaller (typically only 30 to 45 Amp-hours, compared to 65 to 85 Amp-hours in a conventional car) because they do not have to crank a heavy starter motor. Consequently, once the DC-to-DC converter stops charging, a small EV 12-volt battery drains to the 10-volt cutoff threshold in as little as 5 to 15 minutes.
  2. Shed 12-volt loads (Seat heaters, defroster, blower fan, headlights in daylight): Even though the A/C compressor runs off high voltage, the dashboard blower fan, rear window defroster, heated seats, wipers, and exterior lights run directly off the tiny 12-volt battery. Shut them off immediately.
  3. Never shift into Park (P) or power off until you are in a tow-accessible spot: Once an EV or hybrid powers down with a depleted 12-volt battery, the electronic parking pawl locks the wheels and the vehicle cannot be shifted into Neutral (N) to roll onto a flatbed tow truck without connecting a 12-volt jump-pack to the under-hood jump posts.
  4. Know where your manual mechanical door release levers are located: If an EV's 12-volt system dies completely after you stop, electronic push-button door latches will not work. Use the mechanical manual door handle release lever located on the front edge of the door armrest or floor sill to exit the cabin.

Emergency transmission shift-lock release and braking after engine stall

When an alternator failure culminates in complete engine and electrical death at the side of the road, two final mechanical hurdles catch drivers off guard during the final 50 meters (165 feet) of coasting and stopping:

  1. Vacuum brake booster depletion (Two-press limit): The moment a gasoline engine stalls, the intake manifold stops generating vacuum for the power brake booster. An intact vacuum check valve holds enough stored vacuum inside the booster canister for 1 to 2 normal power-assisted brake presses. If you pump the brake pedal lightly three or four times while coasting, you vent all stored vacuum and the brake pedal becomes rock-hard. Instead, apply one single, continuous, firm press on the brake pedal to bring the stalled car to a complete halt, and brace your back against the seat to push harder if the pedal stiffens.
  2. Using the mechanical Shift-Lock Override slot to get into Neutral (N): If your battery dies completely below 8.5 volts after you shift into Park (P), the electric brake-shift interlock solenoid will have no power to release the gearshift lever when the tow truck arrives. Locate the small rectangular plastic cover (SHIFT LOCK) right next to the base of the console gear selector, pry the tiny cap off with a key tip or flathead screwdriver, press your key straight down into the slot to mechanically depress the lock pawl, and pull the shifter into Neutral (N) while holding the foot brake.

Tip

Keep a pocket 12-volt plug-in USB adapter with a digital LED voltmeter display in your car's cigarette lighter / power socket. When the engine is running normally, the display reads 13.8V to 14.4V. If you ever see the digital readout drop to 12.5V or lower while driving, you will know immediately that your alternator has stopped charging, often minutes before the dashboard computer triggers the red battery warning light, giving you maximum time to shed loads and exit the highway safely. Consider taking a hands-on roadside safety and first aid course from the Red Cross, St John Ambulance, or your national motoring club.

Does the red battery light coming on while driving mean I need a new battery?

Almost never. When the red battery-shaped icon illuminates while the engine is running, it means your car's charging system (almost always the alternator, voltage regulator, or serpentine drive belt) has stopped generating electricity, and the car is now running solely on the limited reserve power stored inside your 12-volt battery. Replacing the battery without fixing the alternator or belt will simply result in the new battery draining dead on your next drive.

How far can I drive after the red battery warning light comes on?

First check your engine temperature gauge: if the serpentine belt snapped and stopped the water pump, the engine will overheat in 1 to 2 minutes and you must stop immediately. If the belt is intact and only the alternator failed, a healthy battery provides roughly 30 to 60 minutes (25 to 50 kilometers or 15 to 30 miles) of driving in daylight IF you immediately turn off the A/C, heater fan, rear defroster, heated seats, radio, and headlights. At night with headlights and wipers running, you may have only 10 to 20 minutes before the car stalls completely.

Why did my ABS, airbag, traction control, and power steering warning lights all come on right after the battery light?

When the alternator fails and the battery drains below 11.0 volts, there is no longer enough electrical voltage to operate high-current safety computers and motors. The car's central computer shuts down the anti-lock braking system (ABS), traction control, airbags, and electric power steering one by one to save the last drops of electricity for the engine's spark plugs and fuel pump. When this dashboard warning-light cascade happens, your engine will stall completely within 1 to 5 minutes; pull off the road immediately.

What happens if my electric power steering shuts off while I am driving?

Your steering wheel is still mechanically connected to the front wheels by a steel steering shaft, so you never lose the ability to steer the car. However, without the electric assist motor (or hydraulic pump if the belt broke), turning the steering wheel requires 4 to 5 times more physical arm strength, especially at slow speeds. Grip the wheel firmly with both hands at the 9 and 3 o'clock positions and keep the car rolling slowly as you steer onto the shoulder.

Should I turn the engine off at a long red traffic light to save battery power when the alternator fails?

Never turn off the engine until you are parked in your final, safe off-road location, and immediately press the "A-OFF" button to disable your car's automatic Start-Stop feature. Once the alternator stops charging, the depleted battery will not have the 300 to 600 amperes of cold-cranking power required to spin the starter motor again, meaning if the engine shuts off at a red light, it will not restart.

Why does my car smell like rotten eggs when the battery light comes on?

A strong smell of rotten eggs (hydrogen sulfide gas) combined with a battery warning light, or headlights that suddenly flare unusually bright, means the alternator's voltage regulator has shorted out and is over-charging the battery at 16 to 19 volts. This boils the sulfuric acid electrolyte inside the battery, venting toxic, explosive hydrogen gas. Pull over, shut the engine off immediately, do not smoke or create sparks near the hood, and let the battery cool before having the car towed.
