On Monday, my BMW dealer replaced my battery. They also performed a voltage draw test, which revealed that my car has a 160ma draw at rest, far beyond the permitted 10ma draw level.

They assured me that as long as I drove the car every day, there won’t be any harm done to my new battery. However, they advised getting a trickle charger if I plan to leave it parked for a long time. I bought the alligator clip model of the BMW Advanced Battery Charging System.

I reasoned that there was no reason why I couldn’t plug it in every night to make sure that the battery wasn’t harmed even with the overnight draw while I tried to identify the source of the 160ma drain.

What surprised me is that even after I unplug the charger in the morning and throughout the night, it remains solid red, indicating that it is still charging. Why doesn’t it turn green is the question I have. There is no reason why a brand-new battery wouldn’t have a full charge in it, so it should turn green after the battery is fully charged.

What does a BMW’s charging system entail?

The 1.25 Amp battery charger in the BMW Advanced Charging system uses sophisticated BTP microchip technology. The lead acid battery in your BMW is recharged using this technology. The battery is then automatically maintained via “float” voltage, eliminating sulfation, which can lead acid batteries to fail.

Advanced battery charge mode: what is it?

To enhance battery health, Advanced Battery Charge Mode employs various techniques outside of working hours in addition to the standard charging algorithm. ExpressCharge is used to charge the batteries more quickly during business hours. The days and the time period during which the battery must be charged are configurable.

How do I reprogramme my BMW now that the battery has been changed?

Here are the instructions so that you can see how crucial the BMW computer reset is after reading the preceding explanation.

  • Once the lights and radio are turned on, first switch the ignition key of the BMW automobile to the accessory position. This must be completed prior to starting the car. Then, hold down the “Trip” button on the instrument panel for a few seconds until the red light appears.
  • Once more, press and hold the “Trip” button until Reset appears.
  • Press the same button a third time after that. The BMW computer will quickly reset now.

BMW automobile battery replacement and computer reset are both inexpensive procedures. The sooner you complete this, the easier it will be for you to operate your BMW vehicle. Despite all of these facts, this surgery should not be taken lightly. There are auto repair shops with qualified experts who adhere to the manufacturer’s warranty guidelines. To receive a safe and secure service, consult these businesses.

How can I turn off accelerated charging?

  • In the left pane, select the Advanced Charge tab.
  • Click the toggle to the On position at the top of the page to enable Advanced Charge.
  • Button Advanced Charge on or off for each day of the week by clicking the corresponding toggle.

What voltage should my battery have, BMW?

Verify the voltage reading. Not more than 12.7 volts, but around 12.45 volts is the ideal range. It could be time to replace your automobile battery if the reading falls below this range.

The BMW hybrid does it refuel while moving?

To get the most performance and power out of your plug-in hybrid car, we strongly advise charging the battery. All-electric driving will be restricted without recharging, and the power reserves for the eBoost feature will be significantly diminished. BMW advises routine overnight charging for maximum efficiency.

BMW plug-in hybrid vehicles also offer on-the-go charging. The plug-in hybrid can recover some energy while braking through regenerative technology. Additionally, the Battery Control Mode feature allows for charging to occur while traveling. By using the electric motor as a generator, this mode continuously maintains the high-voltage battery charge at the desired level or increases it to the preset value. In this manner, for instance, it is feasible to employ Battery Control Mode during a highway trip to safeguard or even boost the electric power reserves so that a later urban route can be driven entirely electrically and without any local emissions.

Your PHEV will still get you where you need to go even if you don’t have time to charge it. Automatic switching to the BMW TwinPower Turbo engine occurs when the battery is completely depleted.

Do BMW batteries require programming?

Registration is necessary so that your vehicle is aware of the modified requirements and is able to adapt to the new battery settings. Otherwise, improperly coding your BMW battery could lead to a variety of electrical issues, including a reduction in battery life, the risk of overcharging or undercharging your battery, or, in the worst case scenario, serious harm to your car’s alternator and electrical system, which could cause your battery to fail before its time.

What kinds of electrical issues could there be? As a result of your automobile assuming that the battery life is low and attempting to conserve it, several modules of your BMW may turn off. So, at that time, it’s possible for your windows and mirrors to not close or open, your radio to not function, your interior lighting to not function, or other modules that are not required for starting or operating a car to fail.

How do batteries get charged configured?

By decreasing the charging threshold so that the battery never fully charges, mostly AC – Extends battery life. Recommended for individuals who use the system primarily with an external power source

What is your rapid charging method?

When you absolutely need your device back online, the majority of Galaxy phones support fast charging and fast wireless charging. Your phone will instantly enable the Fast cable charging feature when you plug in a Samsung Fast Charger. You can explicitly activate this function, but it ought to be enabled by default.

Only a few phones support super fast charging, and you must use the included charger or a 25W or 45W converter that has been approved by Samsung.

Navigate to and enter Settings, then select Battery and devicecare to access the charging option.

The switch for fast, ultra-quick, or fast wireless charging should be tapped.

Connect the USB cord to the phone, then insert the USB power converter into an electrical outlet to begin Rapid or Super fast charging.

You can take the charger out of the smartphone and the outlet once the phone is fully charged.

Note: Only a select few smartphones, including the Note 10+, S20 Ultra, and S22 Ultra, enable 45W charging.

What occurs with an unregistered BMW battery?

The servicing procedure “Register battery replacement” must be executed after installing a new battery. To let the power management system (software in engine electronics and an intelligent battery sensor) know that a new battery was put in the car, the battery replacement must be registered. The power management won’t work effectively if the battery change is not registered, which could result in certain tasks being restricted by particular electrical consumers being turned off or having their power consumption lowered. Power management will charge the new battery as if it were the old, worn-out battery, resulting in the replacement battery failing sooner than expected.

Important! The on-board computer’s display may show inaccurate values if the new battery hasn’t been recognized because of outdated information in the power management system (check control message “Recharge battery” appears even though the battery is new).

The power management in the Digital Engine Electronics (DME) or Digital Diesel Electronics (DDE) is alerted by a servicing function when a battery needs to be replaced. The following actions are carried out:

  • 2. Changing a battery with a different capacity but the same kind (registration/conversion)
  • 3. Changing to a new type of battery (for programming, conversion, or registration)
  • 4. Software updates for the entire battery management system

For vehicles with EfficientDynamics, changes to the charging profile also impact how the Start/Stop system functions.

Car 1:

The battery is being replaced with an identical one. To inform the car that the battery is new, you register replacement so that the charging profile can be modified appropriately. If you don’t, the car will try to charge an outdated battery and eventually fail.

Car 2:

You replace a Standard LA battery with an AGM (or vice versa). Because the charging profile will be for the wrong sort of battery and accelerate battery failure, if you don’t register the replacement, it will toast the new battery for similar reasons to Car 1 but even worse. You MUST utilize a “conversion” in this scenario to switch the battery type. Register a replacement after that.

The vehicle must remain stationary with its new battery installed for at least 3 hours after a battery replacement. It is not feasible to verify with any reliability the state of charge of the new battery until that time. Possible The battery’s complete discharge-related Check Control signals are then hidden.

After a power supply interruption, some systems’ range of use may be constrained. Individual settings might also be lost.

Depending on the equipment specification, settings or activations are required. For instance:

  • Autonomous engine start-stop function (MSA) vehicles: The MSA function is only operative after a learning period (the vehicle must not be awakened for approximately 6 hours).

The lifespan of a battery in these cars, whether an AGM or ordinary battery, can be significantly shortened by skipping the battery registration step. On a late model BMW, skipping battery registration can be one of the problems that results in premature battery failure. For more information, see the topic on Energy Diagnosis.

How can I activate charging mode?

You may control the sort of connection your Android device establishes when you plug in a USB cord. Make sure the charging capability is turned on and has not unintentionally been disabled if you’re charging another device with your laptop.

To access USB options, go to Settings > Connected Devices. Make sure the Charge linked device toggle is turned on in the list of choices.

(Note: If your device is not currently connected to a USB cord, you will not be able to alter any parameters in this menu.)

Is battery health improved by slow charging?

The most favored and independent method for charging an EV battery is slow charging. For NMC batteries in particular, it offers the longest possible battery life (cycle life) and is safer than quick charging. Since the EV owner simply has to pay for the electricity, it is also the least expensive method of charging the EV battery. In order to speed up the adoption of electric 2Ws and 4Ws for the personal use segment, its use must be made more commonplace at work. Owners of electric 2W vehicles can use the workplace charging stations by bringing their chargers with them. Additionally, by choosing this option, any form of uncertainty brought on by variations in charging connectors in the electric 2W region is avoided.

A 2W or 3W battery needs 4 to 5 hours to completely charge on a slow charger. Electric vehicle (EV) manufacturers assert that slow charging extends battery life. However, what good does it do to charge lithium-ion batteries at the same rate as lead-acid traction batteries?

If EV makers included a higher ampere rated charger with the EV, “slow charging” could go more quickly. The charging time would be cut in half by utilizing a charger with a double the ampere rating.

The standard 6A charger offered by 2W OEMs costs about INR 2,300. Costs for a 15A charger are roughly INR 4,000. Similar circumstances apply to electric 3Ws, where OEMs normally offer a 15 A charger for roughly INR 4,000. They may offer 30A for about 7,000 Indian rupees. The entire experience of EV ownership can be significantly enhanced in terms of time spent to charge the vehicle at home or work by slightly increasing the vehicle’s absolute price.
