Power Loss Problem in the Taycan and Audi E-Tron GTs
There were a lot of rumors and predictions when Tesla announced a major recall of its vehicles related to faulty lithium-ion batteries. But nothing could have prepared anyone for what unfolded.
Porsche will actually recall 43,000 electric cars with the engine control unit (ECU) that are affected by a design flaw that can be traced to the same company’s previous recalls. And the ECU maker says it’s cooperating with the company to fully investigate the problem.
The company will also announce an additional 5,000 recalled vehicles.
Tesla Motors recalled an estimated 10 million cars worldwide as a result of the discovery of a design flaw that could affect the use of the lithium-ion batteries in the cars.
The problem was discovered in 2017, but nobody at Tesla ever found out that the battery cells that are used in most vehicles were also faulty. And when the problem was discovered, Tesla executives were told to rush to fix the problem as quickly as possible, but they failed to do so.
That means that vehicles with lithium-ion batteries that have the faulty cells are not affected.
And it’s not just the batteries that had to be changed. The cars’ cars were also changed to prevent the cars from getting broken down in the middle of the night due to the faulty cells.
So in other words, Tesla didn’t discover the problem until the car owners noticed the problem and started reporting it to Tesla.
According to the news release, the ECU maker received a complaint from one Tesla customer who reported that her car had an irregular behavior when starting.
“At any given time, the ECU would make an adjustment or make a software change and then proceed to start, and the engine would not start. This behavior is not normal for electric vehicles and is very annoying to drive,” the company spokesperson said.
“The ECU had determined that the car needed an adjustment to make certain that all of the car’s subsystems were functioning correctly and that the ECU could start the car.

In the case of the Taycan and Audi E-Tron GTs, the power loss problem is a software issue only, i. , there are no physical limitations. The power loss problem occurs on each of the electric motor motors that are on board the E-Tron GTs in all modes of operation when power is lost to the motor during charging.
When a motor operates in the first mode – where power is supplied to the motor – when the electrical energy is lost to the motor, the voltage supply to the motor is reduced to a value less than the voltage required to supply the electrical energy to the motor. This problem is generally corrected in software, so that no voltage is actually drawn from the battery when the battery is being charged. The electric motor will still run, i. , the motor will provide power to the battery when it is being charged, and the voltage supplied to the motor will not be reduced.
When the same motor operates in the second mode – where power is applied to the motor when the battery is being charged – when the electrical energy is supplied to the motor, the motor will run at a reduced load. As a result, the battery voltage will increase. The increased battery voltage to the motor will reduce the motor’s speed.
To overcome the power loss problem, the power loss has to be calculated in the software, so that no voltage is drawn from the battery when the battery is being charged. Power loss can be calculated automatically, either through a software program that does not know the electrical load on the motor, or through a software program that knows the electrical load on the motor when it operates in the second mode.
Case of a 12-volt battery failure: a Porsche owner’s report.
Article Title: Case of a 12-volt battery failure: a Porsche owner’s report | Software.
I’m reporting a battery failure within a Porsche 952. The original owner’s report is attached for reference.
) I have the original 952 and after an accident on May 27, I was unable to get it started. When I tried to restart it several times, it would not be able to start.
) The 952 seems to have a problem with the battery, it will not start.
) The battery is 12 volts so it would seem the only option would be to replace the battery.
The owner has not reported any further problems. The owner does not know what to do.

The problem of 12-volt batteries in the electrical cars
Summary: The problem of 12-volt batteries in the electrical vehicles.
The following article first appeared on Software Magazine.
When we think about electric vehicle batteries, the electric vehicle industry is thinking about the traditional “triode” technology. That is, lithium-ion batteries with high energy density, high specific energy and high power-to-weight ratio. The typical automotive battery is made from several battery cells that are charged and discharged in parallel, and are therefore unable to simultaneously charge two cells, and can only use a single charge for the battery’s life. However that is a limitation of the technology, and in the future it will also become the limiting factor for battery’s performance.
It is also the main technology to charge the batteries of electric vehicles (EV) in the future. It is because of the low energy density of the single-cell (cell with a single battery cell) as well as the need to charge several cells simultaneously, that the majority of the large electric vehicles in the future will be the hybrid – i. EV without the traditional triple-voltage batteries. With such a hybrid vehicle, batteries are charged at the end of the day, when the battery has to be recharged, and the whole electrical system is not stopped. This is why, in the future, more than half of all the EV’s in the world will be equipped with a 12-volt battery.
The problem with electric vehicles with 12-volt batteries is that they are quite heavy compared to the weight of the traditional lithium-ion batteries. When the vehicle is powered by a traditional lithium-ion battery, the weight of the battery, its internal structure and the weight of the battery cell itself are about the same as the weight of the vehicle itself, except that it is lighter than the typical motor. So even if the battery’s weight is the same, the electric vehicle weighs more. The increased weight, both inside the battery and the vehicle, can affect negatively the efficiency of the electric vehicle and the driving characteristics of the electric vehicle.
The 12-volt battery has also a strong influence on the vehicle’s energy efficiency. The internal resistance of the battery is lower than the internal resistance of the vehicle, therefore the motor can be optimized to the current state of the battery.
