It’s trending these days… Mild Hybrid What is it?

Hybrid cars are very popular these days.
Less charging than electric vehicles
In terms of fuel efficiency, driving performance, and maintenance cost
It has advantages over internal combustion locomotives.
You seem to be getting a lot of attention.

Today’s car is a Toyota
This is a Camry Hybrid.
One of them is the XSE model.
It is a slightly sportier model than the base model.
Then, looking at the vehicle in general,
Also, while driving, I learned about hybrid cars.
Let’s take some time to learn more.

There are a lot of hybrid cars out there.
mild hybrid, plug-in hybrid,
You’ve probably heard of these terms.
“Aren’t they all hybrids?”
but you can think
Subtly different.

Hybrid cars are largely mild hybrids,
Plug-in hybrid, regular hybrid
It is divided into three categories:
The difference between these three
It’s in ‘Power’.

mild hybrid
For internal combustion locomotives using 12V voltage
48V voltage is added
48V is not a large enough voltage to run a car.
Electric motors alone cannot drive it.
So there is no pure EV mode.
The motor drives the engine
It acts as a booster.
Recovers energy when decelerating
It also acts as regenerative braking.

in the fortress vehicles
There are so many electronic devices.
12V low power only
It will be difficult to cope with the existing electronic equipment.
So the engine intervenes.
This will affect the fuel economy of the vehicle.

When 48V voltage is applied at this time,
This will solve this problem to some extent.
So it has an effect on fuel efficiency improvement.
Compared to the actual internal combustion locomotive, the fuel efficiency is improved by about 15%.

Mild hybrid in Europe
It is a hybrid system that is widely adopted.
Korea and Japan
I don’t use a lot of mild hybrid systems.
This probably happened in Europe
‘Dieselgate (exhaust gas manipulation case)’ and
It’s related.
Emissions regulations need to be met
European automakers
A hybrid system that could be made in a hurry
It was a mild hybrid system.

From conventional internal combustion locomotives to hybrid vehicles

A hybrid system by changing the engine entirely
rather than separately
much in terms of price and time
tends to be shortened.

Because of the regulations at the time, the hybrid system was
European cars that had to be released quickly
I had to hire a lot.
It was the system.

On the other hand, Korean and Japanese vehicles such as Hyundai and Toyota

There was no need to adopt it.

There is a difference in power.
Both battery capacity and output will increase.
So, the motor can run on its own.

Normal hybrid and plug-in hybrid
It differs from the name.
The reason ‘plug-in’ is attached to the name is external charging.
saying it’s possible.
It only supports slow charging.
As a result, compared to a typical hybrid car
It’s almost like an electric car.

plug-in hybrid car
50-60 km on a single charge
It can be driven by an electric motor.
Those who do not need to drive long distances,
‘The distance to and from work is around 50km round trip’
For those who do
There is an advantage in terms of fuel costs.

However, the charging infrastructure is not within the range of life.
If charging is burdensome
A better alternative to a regular hybrid car
looks like it could be.

Above all, plug-in hybrid cars
the price is expensive.
Because it takes more battery.

For some people, the fuel cost advantage is after 6-7 years of driving.
It goes beyond the downside of the high price.
If you are a long-term car driver
plug-in hybrid car
It could be a better option, but
If the vehicle replacement cycle is fast
general hybrid car
It could be a more sensible choice.

Of course, plug-in hybrid cars
You don’t have to charge it.
But if that’s the case, a plug-in hybrid car
It doesn’t make sense to spend a lot of money on it.

It is a mixture of parallelism characteristics.

EV mode only at low speed
using battery power
You can see the car running.
In the section where the engine is decelerating or the use of the engine is reduced
Power is supplied to the battery through regenerative braking
It’s saving.

Toyota hybrid system
There are two electric motors.
One helps the driving power of the engine,
1 by recovering electricity when decelerating
It serves as a charger.

Because two motors are used
There can be chaos internally.
To avoid that confusion, Toyota
I developed a ‘power split device’.
This is Toyota’s unique technology.

The power split device runs from the motor to the engine.
Minimizing the sense of heterogeneity when power sources pass
plays a role.

when the engine starts to intervene
There is no sense of disparity, such as crying.
It’s very smooth to drive.
As a result, I repeat the process of going and standing like this.
in city driving
Driving stress is definitely reduced.

Because there is a motor to assist the power
It also has the effect of improving fuel efficiency.

Hybrid cars among Toyota sales (based on domestic standards)
It accounts for 88%. That’s a huge part…
Lexus, Toyota’s top brand
The hybrid ratio is as high as 98%.
The Toyota brand itself
In hybrid technology
It can be said that it is in a unique position.

A hybrid car as a mass-produced car
Toyota was the first company in the world to develop it.
The 1997 Prius is that car.
I’d say it was groundbreaking at the time.
Its reputation continues to this day.
