Vehicle Architectures 

There is currently a wide range of different vehicle concepts covering automotive needs: 

  • Micro Hybrid Electric Vehicles (HEVs) are also referred to as start-stop systems because the engine turns off when the vehicle stops and starts automatically when the car is powered, 
  • Mild Hybrid Vehicles, which include the storage and re-use of braking energy
  • Total Hybrid Electric Vehicles which use the electrical storage system for relatively short distances,
  • Plug-in HEVs (PHEVs), which combine the advantages of an electric vehicle with those of a vehicle using a combustion engine, 
  • Electric Vehicles (EVs) are operated with electrical power only. 

Micro Hybrid Electric Vehicles

 Micro Hybrid Electric Vehicles (mHEV) are hybrid electric vehicles (HEV) designed to improve fuel efficiency and reduce emissions. Unlike full HEVs, mHEVs do not have a pure electric driving mode and rely primarily on the internal combustion engine (ICE) for propulsion.

In an mHEV, a tiny battery and electric motor assist the ICE and capture energy from regenerative braking. This energy is stored in the battery and used for auxiliary power systems, such as air conditioning, lighting, and radio, reducing the load on the ICE. This results in improved fuel efficiency and reduced emissions. Belt-driven alternator starters (BAS) – a type of mHEV that use a belt-driven alternator to provide electrical assistance to the ICE and capture energy during regenerative braking.Start-Stop systems – an mHEV that automatically turns off the ICE when the vehicle comes to a stop and restarts when the driver presses the accelerator pedal.

Mild Hybrid Vehicles

Mild hybrid vehicles use a small electric motor and a battery to help the internal combustion engine work better and get better gas mileage. Unlike full hybrids, mild hybrids cannot run solely on electric power, and the electric motor provides only a minor boost to the engine, hence the term “mild.” Most of the time, these systems use a belt-driven starter generator to collect energy when the car slows down and boost it when it speeds up. They may also allow the engine to shut down temporarily at stop lights, improving fuel efficiency.

Total Hybrid Electric Vehicles 

Total hybrid electric vehicles (HEVs) move with the help of both an internal combustion engine and an electric motor powered by a battery pack. The electric motor and the gasoline engine work together to provide the power needed to drive the vehicle, with the electric motor often used for low-speed driving and the internal combustion engine kicking in for higher speeds and heavy loads. The engine can recharge the battery pack or use regenerative braking. The electric motor acts as a generator, turning the car’s kinetic energy into electricity to charge the battery. This makes HEVs more fuel-efficient and lower emissions than conventional gasoline vehicles. Some HEVs can also run solely on electric power for short distances, reducing emissions and fuel consumption.

Plug-in HEVs 

Plug-in hybrid electric vehicles (PHEVs) are a type of hybrid electric vehicle that can run on an internal combustion engine and electric power from a rechargeable battery. The battery can be charged by plugging the car into a wall outlet or a charging station, which is why the term “plug-in” is usMost plug-in hybrid electric vehicles (PHEVs) have bigger batteries than traditional hybrids, so they can go farther on electric power alone before the gas engine kicks in. combustion engine kicks in. This results in lower emissions and improved fuel efficiency, especially in urban driving, where electric power can be used for most trips. PHEVs also have the advantage that they can use gasoline for longer trips. This removes the worry about running out of gas and makes them a better choice for many drivers.

Electric Vehicles (EVs)

Electric vehicles (EVs) run solely on electricity stored in a rechargeable battery. They have an electric motor instead of an internal combustion engine and produce zero emissions while driving. The battery can be recharged from an external source, such as a wall outlet or public charging station, and the time required to charge the battery entirely depends on the size of the battery and the charging station’s power. EVs offer several advantages over conventional gasoline vehicles, including lower operating costs due to the lower cost of electricity than gasoline, improved efficiency, and reduced environmental impact. They also offer smooth and quiet operation and instant torque from the electric motor for quick acceleration. However, the range of EVs is currently limited compared to gasoline vehicles, and the time required to recharge the battery can still be a drawback for some drivers.

Battery Energy Storage  

A method for storing electrical energy that relies on electrochemical charge/discharge reactions is known as a rechargeable battery. Chemical energy is utilised in direct proportion to the amount of electrical energy stored in a battery.

Rechargeable batteries come in various designs and sizes, ranging from tiny button cells to enormous batteries used as backup energy storage in industrial applications. The four battery technology families that now rule the market have led to various chemical combinations being employed frequently: Nickel, Lithium, Lead, and Sodium.

Energy can be stored in different forms as compressed air (pneumatic), flywheels (kinematic), thermal storage (heat), and hydrogen (chemical). Battery Energy Storage (“BES”) systems should be distinguished from other storage devices for several reasons. First and foremost, they are highly flexible and can be adapted to high-power and high-energy applications. When correctly selected or tailored, they are also highly efficient both during use and on standby. BES systems increase road vehicle applications’ overall efficiency– current and future. 

 There are two batteries in a hybrid electric vehicle, including a plug-in hybrid electric vehicle—a 12-volt battery and a hybrid battery, just like in a car with a combustion engine.

Both batteries function fundamentally in a similar manner. They both have a positive and negative electrode submerged in an ion-rich fluid called an electrolyte. Ions, or atoms with an electrical charge, interact intricately with electrons to produce electricity.

The 12-volt battery produces enough electricity to start the car. However, the hybrid electric battery has enough power to propel the vehicle.

The second thing to understand is that a hybrid electric battery is a battery pack that contains and links several separate cells rather than a single battery or cell. For instance, the battery pack in the Toyota Highlander Hybrid comprises 240 cells. The real driving force behind the car is the sum of all its cell powers.

Batteries made of nickel-metal hydride (NiMH)

Nickel-Metal Hydride (NiMH) batteries are a type of rechargeable battery that uses a hydrogen-absorbing alloy as the positive electrode (cathode) and nickel hydroxide as the negative electrode (anode). They were first commercialised in the 1990s and have become a popular alternative to traditional nickel-cadmium (NiCad) batteries.

One of the main advantages of NiMH batteries over NiCad batteries is their higher energy density, which allows for a higher capacity in a smaller size and lighter weight. This makes them well-suited for applications where weight and space are at a premium, such as portable electronic devices and electric vehicles.

Another advantage of NiMH batteries is their relatively low environmental impact, as they do not contain cadmium, a toxic heavy metal that can cause ecological damage. NiMH batteries are also more resistant to the “memory effect” that can reduce the capacity of NiCad batteries over time.

However, NiMH batteries are typically more expensive than NiCad batteries and have a lower self-discharge rate, meaning they lose more energy when not in use. They are also more sensitive to overcharging and over-discharging, which can reduce their lifespan and performance.

In summary, NiMH batteries are a popular alternative to NiCad batteries, offering higher energy density, lower environmental impact, higher cost and lower self-discharge rate. They are widely used in various applications, including portable electronic devices, electric vehicles, and renewable energy systems.

Lithium-ion (Li-ion) Batteries

Lithium-ion (Li-ion) batteries are rechargeable batteries that have become widely used in various applications, including consumer electronics, electric vehicles, and renewable energy systems. They have several advantages over other types of batteries, including higher energy density, longer lifespan, and lower self-discharge rate.

Li-ion batteries consist of a cathode, an anode, and an electrolyte, with lithium ions moving from the anode to the cathode during discharge and back during charging. They offer high energy and power density, so they can store a lot of energy in a small package and deliver it quickly when needed.

One of the main advantages of Li-ion batteries is their relatively low self-discharge rate, meaning they lose relatively little energy when not used. This makes them well-suited for applications where the battery needs to be stored for long periods between uses.

However, Li-ion batteries can be expensive and more sensitive to high temperatures, overcharging, and over-discharging than other batteries. Handling and using Li-ion batteries properly ensures their safe and effective operation.

Overall, Li-ion batteries are an essential part of the energy storage landscape. Their widespread use has been a critical factor in the growth of renewable energy and electric vehicles.
