Bit Serial Data Interface Bmw X1

BMW Advanced Battery Charging System with Alligator Clips. Drama korea full house. Or DDE (Digital Diesel Electronics) via the BSD (bit-serial data interface).

Intelligent Battery Sensor (IBS) The IBS contains a micro-processor that is used to monitor/measure various battery conditions such as:. Terminal voltage via measurement from B+ to Gnd.

Charge/discharge current via integrated shunt resistor. Temperature of battery acid via integrated temp sensor The IBS is able to withstand thermal loads up to 105°C, the chemical effects of the battery acid. IBS Measuring/Evaluation Function The measuring/evaluation function of the IBS electronics, continuously measures the following values under all vehicle operating conditions:. Voltage (6V to 16.5V). Current (200A to +200A). Closed Circuit Current (0A to 10A).

Starting Current (0A to 1000A). Temperature (-40C to 105C) When the vehicle is stationary, the IBS is programmed to wake up every 14 sec. And makes the required measurements within approx. 50 ms in order to save power.

The measured values from the IBS are provided to the DME by way of the Binary Serial Data Interface (BSD) to calculate the State of Charge and State of Health for the battery. State of Charge (SoC) is a calculated condition showing the current charge of the battery. SoC is used during key ”OFF” periods to insure the battery maintains a sufficient charge to start the engine at least one more time. State of Health (SoH) tracks the history of the battery. Charge/dis-charge cycles and times are monitored. SoH helps the DME determine the proper charging rates and anticipated battery life. Internal resistance of the battery is calculated by the IBS from the current and voltage dip during engine start.

The values are forwarded to the DME to calculate the SoH of the battery. Software contained in the microprocessor of the IBS utilizes the measured values to calculate the State of Charge (SoC) of the battery during vehicle sleep mode and compares this information with that received from the DME/ECM pertaining to the battery SoC/SoH, during the period of time between engine “OFF” and deactivation of the DME main relay. The current SoC/battery data is stored in the IBS every 2 hours over a 6 hour time frame, providing 3-2 hour snapshots of battery SoC information. The stored information/snap-shot data is overwritten every 6 hours.

Whenever KL15 is activated the IBS updates the DME with the current closed circuit histogram/battery status information, by way of the BSD. Upon obtaining updated information the DME evaluates the new data and if a closed-circuit current draw is identified a fault will be stored in the fault memory of the DME. Servicing the IBS The IBS is very sensitive to mechanical stress and strain. It is serviced as a complete unit with the ground cable.

The ground cable also serves as a heat dissipater for the IBS. Google flappy bird. Bryce was one the most honest and knowledgeable auto repair expert I have ever encountered. He is trustworthy and knows what he is taking about. I took my BMW 528 i to another mechanic and they wanted to charge more than $4000 for an electrical issue. Bryce ended fixing the electrical issue for under $200. He has high tech equipments and he really just wants to fix up the car. It is his hobby so he lives trouble shooting and telling you every step of the way.

He is very responsive and super nice. He even gave me a follow up call to make sure my cars is okay and made sure I took it back for a follow up. I would highly recommend Bimmerscan for any BMW electrical issues. Thank you Bryce! I have been having intermittent no start condition since acquiring the car two years ago. It is a 96 BMW 318ti with a S52 (M3) motor.

The swap was done by the previous owner in Virginia and I bought it for my occasional use as a track car. I had been unable to diagnose the problem and was talking to Bryce at BimmerScan about it. He took the time to scan the electrical system and determined that the ground strap was bad.

We replaced the cable and re-tested and found that was the appropriate fix. I was going to swap the battery to see if that was the problem, then wonder if the alternator was bad and then. BimmerScan solved the problem without my throwing money and parts at it hoping to find a fix. Gas mileage has improved, performance is much better and it Starts every time now. Thanks Bryce @BimmerScan. I cant say enough about bryce/bimmerscan. This guy is THE MAN!

I first went to him with my e38. This car was bought new in 2001 and i only have 65k miles on it but the dash was always lit up like a Christmas tree! Since day one this car had electrical issues and every time the dealership said they fixed it, the same issue would pop up. In one hour bryce diagnosed the problem and fixed it!!

Not one issue since! THEN, i took my 2014 (f31) 328ix sport wagon, now this was the cool stuff. He had all these special codes to do some really trick stuff to the electronics like using the key fob to close my rear hatch, roll up my windows and sunroof, as well as fold my mirrors when i lock the car. All my phone contacts in my heads up display. I mean he had like 10 pages of stuff he could do but i just didn't have the time that day, but i will be going back for sure! Needless to say i would absolutely recommend him to anyone. Cool guy, very laid back and not pretentious whatsoever.

I drive a 2009 135i. I began having some weird electrical problems with the radio. Having heard of Bimmerscan before, I already knew that I was going to take it there.

I had heard nothing but great things about Bryce. Bryce did a quick diagnostics test, and within minutes had an answer for me. It was a simple fix and Bryce charged me an extremely reasonable price. I will recommend him to ANY BMW owner who is having any electrical issues on their car. Bryce truly takes care of his customers. I am very thankful to have a person like him in our local community.

Further information on the official fuel consumption and on the official specific CO2 emissions of new automobiles can be found in the guidelines on fuel consumption and CO2 emissions of new automobiles which are available free of charge at all retail outlets and from DAT Deutsche Automobil Treuhand GmbH, Hellmuth-Hirth-Str. 1, 73760 Ostfildern, Germany. Maximum speed optionally with high-speed setup. All engines meet the EU6 emissions standard. Fuel consumption is determined in accordance with the ECE driving cycle (93/116/EC) made up of approximately one third urban traffic and two thirds extra-urban driving (based on the distance covered). CO2 emissions are measured in addition to fuel consumption as such.

Fuel consumption levels are calculated on the basis of vehicles with standard equipment. Special equipment (e.g.

Wider tyres) can have a significant impact on fuel consumption and driving performance levels. The technical data specified apply to vehicles in the German market. The models illustrated may, in part, include optional equipment and accessories not fitted as standard.

According to the specific requirements of other markets, alterations may occur regarding models, standard and optional equipment as described in the text and illustrations. For precise information, please contact your BMW Partner.

Unladen weight (EU) in kg: the figure quoted includes a 90 per cent tank filling, 68 kg for the driver and 7 kg for luggage. Unladen weight applies to vehicles with standard equipment. Optional equipment may increase this figure. Rated output: BMW recommends the use of super unleaded 95 RON fuel.

Unleaded RON 91 fuel or higher with a maximum ethanol limit of 10 per cent (E10) is also permitted. The performance and fuel consumption rates listed are based on the use of RON 98 fuel.
