Hybrid Drivetrain Options: Navigating the Advantages and Disadvantages in today's context

With the rising popularity of EVs, Hybrid tech is besides gaining traction. There is simply a batch of speech connected the forum regarding antithetic Hybrid options and their pros and cons. So present is thread to screen each the antithetic hybrid thrust bid options.

The hybrid powertrains tin beryllium represented successful the pursuing diagram

Parallel Hybrid

Parallel hybrids person a electrical motor, interior combustion motor (ICE) and a tiny battery. They are of 2 types of implementation successful parallel hybrids

1. Parallel Hybrid aka Mild Hybrid

These vehicles person a tiny Li-Ion artillery which is integrated with Integrated Starter Generator. The car has regenerative braking to complaint the tiny battery. This helps successful the followings functions

1. Auto Start/Stop - The motor shuts down erstwhile the car is idling and starts it up erstwhile you privation to determination ahead
2. Torque assistance to the ICE

Pros:
1. Slightly higher substance ratio than axenic ICE

Cons:
1. No axenic electrical thrust capability
2. No large simplification successful process tube emissions
3. Engine cranks each clip you commencement the car, nary soundless commencement up.
4. Annoying motor shutdown and startup successful postulation

Examples - Maruti Smart Hybrid oregon Toyota Neodrive used successful cars similar XL6, Fronx, Brezza, Grand Vitara and Hyryder

2. Series - Parallel Hybrid aka Strong Hybrid

These vehicles person a tiny Li-Ion artillery (around 1 KW) which is integrated with a electrical centrifugal positive determination is simply a ICE. Both the ICE and electrical centrifugal tin powerfulness the wheels utilizing a powerfulness divided instrumentality and planetary gear. The car has regenerative braking to complaint the tiny battery. There are antithetic scenarios successful which either ICE oregon electrical centrifugal oregon some powerfulness the car -

1. Dedicated EV mode which gives 2 - 3 kms scope nether airy acceleration and astatine speeds nether 40 kmph
2. Electric centrifugal powers the wheels and motor charges the artillery successful changeless velocity thrust conditions beneath 75-80 kmph
3. Electric centrifugal positive ICE powerfulness the wheels nether mean acceleration
4. Heavy acceleration oregon speeds supra 80 kmph - Petrol centrifugal powers the wheels

Pros:

1. Higher substance ratio than a axenic ICE oregon mild hybrid car which entails to little moving cost
2. Lesser per km emissions than axenic ICE car oregon mild hybrid car

Cons:
1. Very constricted axenic electrical thrust capability
2. Still pollutes the municipality areas
3. Complex setup needs much components and algorithms to power betwixt centrifugal and ICE.
4. Uses eCVT gearbox
5. Costs much than Mild hybrid oregon Pure ICE car. Example - Toyota Hyryder mild hybrid V AT is Rs. 17.24 lakh ex- showroom and beardown hybrid V AT is Rs. 19.99 lakh ex-showroom

Examples - Toyota Hybrid or Honda e:HEV (Honda has a somewhat antithetic implementation) used successful cars similar Maruti Grand Vitara, Toyota Hyryder oregon Honda City

Series Hybrid aka Range extended electrical vehicle

These hybrids besides person a artillery (slightly larger than a bid parallel hybrid vehicle), electrical centrifugal and ICE. The quality being the ICE enactment arsenic a generator and the wheels are lone powered by the electrical motor. The car has regenerative braking to complaint the battery. The tech is presently implemented by Nissan presently successful its e-Power cars. Nissan uses 2.1 KWH artillery to powerfulness the electrical motor. The artillery is charged arsenic required by a 1.5 L adaptable compression ICE. It tin alteration its compression betwixt 8:1 to 14:1 for antithetic driving conditions. Lower compression for dense driving and higher compression for sedate/steady driving conditions

Pros:
1. Better thermal ratio arsenic the ICE operates successful optimal RPMs.
2. Higher substance ratio than a axenic ICE oregon mild hybrid car which entails to little moving cost
3. Lesser per km emissions than axenic ICE car oregon mild hybrid car
4. Lesser complexity than a bid parallel hybrid
5. No gearbox needed

Cons:
1. Very constricted axenic electrical thrust capability
2. Still pollutes the municipality areas
3. 95 RON substance required owed to adaptable compression

Examples - Nobody is selling wide marketplace bid hybrid cars successful India. Maruti is talking astir bringing bid hybrid successful Fronx successful 2025. Nissan sells bid hybrid cars extracurricular India.

Plugin Hybrid

These hybrids are thing but bid parallel hybrid oregon bid hybrid with a larger battery. The artillery tin charged from an outer powerfulness source. These cars person an electrical lone driving scope of 50 to 75 kms connected a azygous charge. And if the artillery gets depleted, it behaves similar immoderate different hybrid car.

Pros:
1. Pure electrical scope sorts retired astir of the metropolis driving uses cases
2. Occasional hybrid trips tin beryllium made without the request of charging the car
3. Higher substance ratio than a bid parallel oregon bid hybrid car. Running outgo successful the metropolis tin beryllium adjacent to EVs and connected highways adjacent to different hybrid vehicles
4. Lesser per km emissions than axenic ICE car oregon mild hybrid car oregon beardown hybrid car.

Cons:
1. In city, the car lugs astir an ICE adding to other weight
2. On highways, the car lugs astir a larger artillery adding to other weight
3. If the idiosyncratic doesn't complaint the battery, it inactive pollutes the municipality areas
4. If the idiosyncratic doesn't complaint the battery, the substance ratio numbers volition spell for a toss
5. Need to sojourn the substance bunk to capable up the petrol tank.

Examples - Nobody is selling wide marketplace plugin hybrid cars successful India. MG has hinted connected bring PHEVs to India.

Some past of antithetic hybrids being covered connected Teambhp

1. Teambhp was invited for a Toyota Hybrid lawsuit successful Japan successful 2013. Toyota showcased some Strong Hybrid and Plugin Hybrid. Toyota launched wide marketplace hybrid successful India successful 2022 - Related thread (Toyota Hybrid Technology: Drive & Experience @ Japan)
2. Nissan enactment e-Power was caught investigating successful India successful 2017. Nissan ne'er launched the merchandise successful India - Related thread (Nissan evaluating e-Power tech for India. EDIT: Note spotted!)
3. Plugin Hybrid for India? - The thread treatment was started successful 2020. Not adjacent 1 wide marketplace plug successful hybrid was launched successful India. - Related thread (Plug-in Hybrids for India?)

Finally the question - Out of these which hybrid powerfulness bid volition you similar oregon volition you similar an EV oregon volition you similar axenic ICE - NA/turbo petrol/diesel

Can you delight explicate what happens present and how? I don't spot a electrical centrifugal here.

This is however it works

Quote:

Maruti Suzuki's Smart Hybrid aka mild hybrid Technology uses an Integrated Starter Generator (ISG) to supply torque assistance to the motor during acceleration. The ISG replaces the accepted starter centrifugal and alternator, and uses vigor stored successful the car's dual artillery setup to assistance the engine. This reduces the load connected the engine, which improves substance ratio and performance
