The battery of the hybrid car is broken. Can it be used as a tanker? Will driving be a bad experience?

When I was a child, my relatives and friends drove an old Passat, and the turbine broke down. He said: "If I don't fix it, I will naturally inhale."

Now that the hybrid battery is broken, can it be used as an oil car without repair?

This depends on the specific model At present, in terms of broad categories, hybrids can be divided into oil-electric hybrid models and plug-in hybrid models. The technical principles of these two models are not the same, so the impact after the battery is broken is not the same.

The driving cost of hybrid electric vehicles will be very high.

What happens to the mixing of planetary gear sets?

Let's talk about hybrid cars.

Zheng Changshun from the School of Mechanical and Power Engineering of Shanghai Jiaotong University published a paper in the journal of Transmission Technology, which briefly analyzed the mainstream E-CVT power split hybrid transmission, and said so. ?

Toyota THS hybrid power system has a principle, that is, a set of planetary gear sets is used to connect the engine, the motor and the wheels, and the transmission of the engine and the motor can be distributed to drive the car.

Kind of like what? It is to pour tea, pearls, milk and tea into a cup, shake it and mix it together.

This whole cup of bubble tea is a planetary gear set, so the power is mixed and transmitted to the tires, and the car can drive, and the milk tea tastes great.

This planetary gear set can also distribute part of the power generated by the engine to charge the battery. As long as the battery is high, the motor can be driven at first, and the engine will rest.

If the battery is broken, the motor will naturally stop moving, and the power of the whole car will be provided by the engine.

Because the engine uses a special Atkinson cycle, the power performance at low speed is quite poor, so there is not much power to directly drive the car.

So in theory, if the battery of Toyota's hybrid is broken, it will be a boring and particularly expensive oil car to drive. Might as well change the battery.

I also searched Camry's hybrid battery, which is broken, and how it actually works.

There will indeed be a lot of startup jitter, boredom, increased fuel consumption, failure of kinetic energy recovery, etc., similar to the symptoms we judged in principle just now.

In addition to the oil-electric hybrid of planetary gear sets mentioned by Toyota just now, such as Honda i-MMD, it uses another set of principles.

A little simpler than Toyota. The engine is directly connected with the wheels and the generator, and then the generator is connected with the battery and the driving motor.

We don't have to worry about the principle, just say three modes.

1 The vehicle only uses batteries and motors to drive the vehicle in pure electric mode. If it is broken, it will not move, and it will not work.

In the second case, the battery power is not so much that it cannot be driven by pure electricity.

Therefore, it is necessary for the engine to work, drive the generator, provide power for the motor-driven vehicle, and store the excess power in the battery. In this mode, the engine does not directly drive the vehicle.

If the battery is broken, the engine can drive the generator and motor to drive the car, but the excess electricity can't be saved.

In other words, when driving in urban areas, the engine can have a rest, thus achieving the effect of reducing noise and fuel consumption. I've been working now, and it's nothing.

In the third mode, it is really difficult for the motor to follow the car when running on an elevated road or high speed. If you can't keep up, the engine will directly output power to the wheels through a certain transmission ratio, and the motor will not participate in the driving.

In this case, even if the battery is broken, it basically has no effect on driving.

Theoretically, if Honda's battery is broken, the car can be driven, but because it can't use pure electric mode, the performance of power and fuel consumption will be almost worse, which may be worse than that of naturally aspirated.

Jason also published a paper "20 17 Guangqi Honda Accord Hybrid Engine Can't Start" in Automobile Repair and Maintenance magazine. From the actual maintenance case.

After the failure of the high-voltage battery, the transmission, speed sensor, instrument panel and other components do not work, and the vehicle cannot even start.

In other words, there is a difference between theory and practice.

If the battery of Honda i-MMD system is broken, it can't move, not at all.

Plug-in hybrid vehicles can be used as fuel vehicles.

After the hybrid of oil and electricity, let's talk about the traditional plug-in hybrid model. I'm here to explain why it's a "traditional plug-in hybrid model".

Because now many plug-in hybrids actually realize the plug-in function after adding oil-electric hybrid batteries, and the essence is oil-electric hybrid. ?

If the battery of this kind of car is broken, except that it does not support the plug-in function, other situations are actually quite similar to the oil-electric hybrid we mentioned earlier.

The traditional plug-in hybrid car is a bit like a mobile phone charging treasure. The charging treasure is broken and the mobile phone can still be used.

Zhang Shubin, Jilin University, Master thesis, Research on adaptive equivalent fuel consumption energy management strategy for plug-in hybrid electric vehicles.

When the battery capacity of the plug-in hybrid electric vehicle is less than the minimum set value, the engine will be driven separately and output the maximum torque. ?

Simply put, the battery is dead and the engine can only drive itself.

However, the batteries of plug-in models are still relatively heavy, such as 5 series, fuel version 1705kg, new energy version 2005kg, which weighs 300kg.

So if the plug-in battery doesn't work at all, it can be used as pure oil, but the extra battery pack will make the car more expensive.

It's like: the charging treasure is obviously broken, and I still can't pull it out, so I have been tied there. It's uncomfortable to use, and it's still dangling in your trouser pocket, right?

Not all hybrid cars can be turned on when the battery is broken.

Therefore, generally speaking, the battery of a hybrid car is broken, which does not mean that it can be used as an oil car.

Although some plug-in hybrid models can be used as oil vehicles, their experience is also poor, uneconomical and uneconomical, so it is recommended to maintain them.
