Dynamic Simulation of Battery/Supercapacitor Hybrid Energy Storage System for Electric Vehicles.The most effective method of increasing the energy efficiency of electric vehicles is hybridization with supercapacitors (SCs).
Supercapacitors have a number of advantageous qualities, including high efficiency, the ability to store enormous amounts of energy, a less complicated charging method, and rapid charge delivery. By using a modelling and simulation approach, the advantages and viability of using SCs in conjunction with parallel batteries in EVs are shown.
The performance of the battery/SC hybrid energy storage system (HESS) was assessed for potential stress reduction and prolonged battery life, and a semi-active architecture with one DC/DC converter was chosen.
Simscape Power Systems in Matlab-Simulink, ADVISOR, and generic battery, SC, and converter models were used to model the HESS. Data from the literature were used to validate the HESS model, which demonstrated good consistency. This suggests that the model is trustworthy and has a good chance of predicting the HESS performance accurately.
Simulations of dynamic behaviour were run for the Tesla S70 electric vehicle. According to the hybridization results, the battery charge was significantly reduced. For the USC06 driving cycle, the average SC power contribution and range extension in the HESS were assessed.
The simulation results showed a number of verified advantages attributed to the HESS, including a significant improvement in system performance due to the deployment of transient currents during acceleration and deceleration that significantly reduce battery stress, a striking improvement in vehicle range due to a noticeable decrease in the number of cycles/year, and insulation for the battery pack at extremely cold temperatures. Additionally, hybridization might make it possible to scale back the size of the EV battery or primary power source.
Numerous applications employ batteries as energy storage systems. Batteries do, however, have some drawbacks, including low power density, a short life span, and relative slow response times in some applications. On the other side, supercapacitors (SC) have a far faster ability to store and release energy than batteries. They do not, however, store as much energy as batteries.
These gadgets are appropriate for high power vehicle applications; they can supply the necessary power to accelerate the vehicle or recover the energy lost during braking. Supercapacitors do not have the same energy density as batteries, hence they cannot be the exclusive power source for EVs. They do, however, offer good alternatives to make up for the high peak of demand during brief periods of time when battery power is not sufficient.
Hybridization of batteries and supercapacitors aids in getting over each component’s limits. Battery life is improved since the stresses placed on them are lessened. In the transportation industry, electrification is a key strategy for reducing greenhouse gas emissions.
Millions of electric vehicles are currently on the road worldwide, and that number will keep rising. A crucial component of the electric car is the energy storage system. The storage system needs to be durable, affordable, light, effective, safe, and reliable. It also needs to take up a little room.
Additionally, it must be made and discarded in an environmentally friendly manner.It’s interesting to note that during grid outages or periods of high demand, electric vehicles can be used as backup storage.
In order to generate energy and power for EVs and Hybrid Electric Vehicles (HEVs), connecting a battery pack with supercapacitors is thought to be an effective way. This is because the combination produces both high power and high energy capabilities.
Hybrid energy storage systems (HESS) based on batteries and supercapacitors have been proposed as a way to reduce the negative effects of dynamic power exchanges on battery life. Most HESS advancements have taken into consideration the usage of a battery-supercapacitor combination due to its availability, similarity in operation, affordability, and, most crucially, the way in which their individual limitations are efficiently compensated for.
For vehicles with electric propulsion, the automobile industry has created HESS. HESS had demonstrated significant progress in optimising the energy recovered during regenerative braking, raising the rate of charging, and lengthening the service life of the battery by lessening the stress of deep discharge.
Additionally, HESS development for household energy storage applications is starting to produce fruitful results. HESS commonly uses AC or DC coupling to connect to the power grid. Power converters are used to regulate the power flow between various ESS components. The cost of using power converters and microcontrollers might vary depending on how complex the control schemes are.
Therefore, there is a trade-off between technological advantages and economic viability, and it is essential in establishing the long-term technical and financial viability of the installation of micro-grids.
There are several potential battery-supercapacitor HESS topologies. The energy management and control mechanisms employed in HESS, in addition to the topology, are essential for optimising efficiency, energy throughput, and longevity of the energy storage components.
In a battery-supercapacitor HESS, the two ESS components can be connected to either a shared DC or AC bus. Common DC bus is the ideal option for independent micro-grids for a number of reasons.
The majority of ESS components and generators for renewable energy work using DC voltage, to start. The need for a power converter is thus reduced by retaining a DC bus.
The total system’s complexity is significantly reduced by the fact that the DC bus does not require synchronisation. DC coupling hence outperforms analogous AC bus systems in terms of efficiency and cost. The simplest and least expensive HESS topology is a passive connection between a battery and a supercapacitor.
As opposed to batteries, supercapacitors (SC) can quickly store and release energy, albeit they are unable to hold as much energy as batteries. Low energy density, rapid cycle time, and extremely high power density are all characteristics of supercapacitors (SC).
In order to generate energy and power for EVs and Hybrid Electric Vehicles (HEVs), connecting a battery pack with supercapacitors is thought to be an effective way. This is because the combination produces both high power and high energy capabilities. Due to their lower energy density as compared to batteries, supercapacitors cannot serve as an EV’s only power source.
In the transportation industry, electrification plays a significant role in reducing greenhouse gas emissions. The electric vehicle’s energy storage system is a crucial component. The storage system must be affordable, light, effective, safe, reliable, take up little room, and have a long lifespan. Environmentally friendly methods should be used in both production and disposal.
It’s interesting to note that at times of grid breakdown or demand spikes, electric vehicles can be used as backup storage. To build a fixed grid-sized battery with a 9 MW energy capacity, Elverlingsen in Germany collects around 2,000 batteries from Mercedes Benz EVs. EVs heavily rely on the lithium-ion (Li-ion) battery technology because of its strength and energy density.
For applications that call for reasonably large current units up to several hundreds of amperes, CRE Technologies developed a hybrid supercapacitor battery that can provide instantaneous power, energy storage for short-term operation, and memory backup.
A lithium-ion supercapacitor hybrid cell has been created by American Lithium Energy Corporation (ALE) that combines the power and cycle life of a supercapacitor with the capacity and energy of a lithium-ion cell. It can quickly cycle without degrading because it combines elements of both a lithium ion battery and a supercapacitor. These hybrid cells allow for quick charging as well as rapid discharge.
The Marshall Space Flight Centre of NASA has created a brand-new solid-state supercapacitor with a rare combination of high capacitance and discharge characteristics resembling those of a battery. In order to power the systems that obliterate off-course space launch rockets, range-safety batteries will be replaced. Rechargeable batteries are used in electric vehicles as well as other commercial uses.
In order to create novel energy management methods based on batteries and supercapacitors for electric vehicles with enhanced thermal battery behaviour, ESTACA, a French Engineering School, has been actively working on a Hybrid Energy Storage System (HESS) Multiphysics model.
