Batteries

Dive into the electrifying world of Battery Management Systems with Vaneet Kumar, VP of R&D at SVOLT, as he unveils how they are revolutionizing electric vehicles' performance and safety.

Up to twice as much energy at the same size: Solid-State Batteries (SSB) are at the forefront of current research and development in the field of electric mobility. They are considered the next big thing that could significantly improve the performance, safety, and range of electric vehicles (EVs). Compared to the currently dominant lithium-ion batteries, which use a liquid or gel-like electrolyte, they offer several crucial advantages.

2024/03/18 - Solid-state batteries replace the liquid electrolyte with a solid one. This not only allows for higher energy density but also increases safety, as the risk of leaks and the resulting fires are minimized.
There are three types of solid electrolyte system, namely oxides, sulfides, and polymer electrolyte...

They each represent different approaches to sustainable mobility: battery electric vehicles (BEVs), fuel cell electric vehicles (FCEVs) and e-fuels for combustion engines. DRIVEN has compared the concepts. Who’s the winner?

2024/03/15 - How do we compare the alternative drive systems?
Various criteria are relevant when it comes to evaluating alternative drive types. In view of finite resources, primary energy consumption is particularly important – this is the total amount of energy that is directly obtained and consumed from natural sources before it is converted into other forms of energy. Primary energy consumption therefore measures the energy input in its original form.

In order to offer drivers of electric cars a simple way of assessing the state of health (SOH) of the battery over its entire service life, TÜV Rheinland is now offering a "Battery Quick Check" in collaboration with Twaice.

2024/03/15 - The condition of the battery is crucial for the resale value of an electric vehicle. Vehicle owners are therefore interested in knowing how far battery degradation has progressed, while potential buyers want to objectively and independently assess the "State Of Health". The battery in electric vehicles is a wear part that deteriorates over time, both through charging and discharging cycles and through the mere passage time. The Battery Quick Check requires that the electric vehicle be connected to...

The German Federal Network Agency’s annual report points out the weak spots: In 2022, around 900 million euros had to be spent on stabilizing the electric grid because grid bottlenecks prevented the use of renewable energies. 

The cost of stabilizing the German electric grid reached an all-time high in 2022. A record value of over 8 billion kWh of renewable energy (compared to 5.8 billion in the previous year) was limited due to grid congestion. This mainly affected offshore (51 percent) and onshore wind power (39 percent). Solar power was also increasingly lost due to grid congestion: the loss rose from 237 million kWh in 2021 to 620 million in 2022...

One goal in battery development is to maximise the number of battery cells in the battery pack of an electric car. But SVOLT's high-speed stacking is about more than that: the process has many significant advantages.

It was an April Fool's joke in spring 2016 when the fast food chain BURGER KING® presented its new "Square" product line on social media. The first square Whopper® was supposed to require 25 percent less transport costs and up to 32 percent less storage space thanks to more efficient use of space. And all this without changing the portion size.
It was no joke when a large coffee retail chain announced at the beginning of 2023 that...

A joint study (only available in German) by RWTH Aachen University and strategy consultants PwC has analyzed the potential of recycling traction batteries. The results give hope for a profitable future. SVOLT is also working intensively on battery recycling.

Batteries that are no longer powerful enough for use in cars are by no means worthless. As a rule, they still have 70 to 80 percent of their original capacity after several thousand charging cycles (depending on the battery type and cell chemistry). In a joint study, the Chair “Production Engineering of E-Mobility Components” (PEM) at RWTH Aachen University and strategy consultants PwC have concluded that...

The energy transition requires a paradigm shift in power supply: storage capacities for green electricity must be massively expanded. Electric car batteries can contribute to electric grid stability. They are particularly sustainable if the batteries are produced in Europe.

CO2 emissions are clearly too high: road transportation must deliver so that EU climate targets are not jeopardized. The figures are a fiasco for European transportation policy: in 2019, road transportation was responsible for 26 percent of all CO₂ emissions in the EU. In 1990, its share was “only” 15 percent. However, while other sectors have significantly stepped up the pace and total CO₂ emissions have fallen by 23 percent since 1990,...

According to the media, it is the “electric car game changer” that makes “electric mobility truly affordable for everyone”: the new Citroën ë-C3 will be launched in spring 2024 and can already be ordered now. 

The small car’s battery scores with its impressive technical details. Two key figures explain the euphoric media response to the small French car from Stellantis: the combination of its low entry-level price of just 23,300 euros (without subsidies) and its range of 300 kilometers according to the WLTP-standard. A combination that was previously unheard of for a five-seater compact car. Until now, customers have either had to dig much deeper into...
