Revamping the 100 in X –
An All-Electric Future
We can evaluate the progress of the automobile by looking at the Tesla Model S Plaid. It reaches 100 mph from a standstill in just 4.3, compared to the 100 mph the Disco Volante reaches in 17.8 seconds.
With the automobile industry reaching the point of electrification, the meaning of “100 in X” is quickly changing. Consumers’ key concerns in switching to electric is range and charge- anxiety.
StoreDot has gone ahead and modernized “100 in X” as we know it today. After all, it is the market leader when it comes to XFC battery technology A.K.A an extreme fast charging. According to them, “100 in X” is “the time, in minutes, to add 100 miles of range during a charging event”. This is way to make it easier to understand for consumers.
An easy-to-understand roadmap has been created to ensure that drivers get the same experience as gas-powered cars. We have to analyze current and also future electric vehicle ecosystems. Many milestones have been set to define “100 in X”. We must keep in mind the technology used in the “extreme semi-solid” and extremely fast-charging battery.
- By 2024, 100 miles charged in 5 minutes
- By 2028, 100 miles charged in 3 minutes
- By 2032, 100 miles charged in 2 minutes
Major Battery Improvements Driving “100 in X”
Battery capacity and energy density are major factors in discussing the total time to charge. There is already a variety of battery capacities. In the next years, greater energy density is going to be dependent on the performance of the cathode and anode. This means, ternary cathodes and silicone-dominant anodes are going to be the driving force for the density of battery cells.
With the current information on nascent and current battery development, energy density during slow charging is going to go from 240Wh/kg to higher than 300Wh/kg in 3 years. At the same time, the nominal pack capacity is going to go from 60kWh to more than 75kWh.
The charge rate of the industry will grow roughly from 2.4C – to 3.0C. The expected charge time from 2021 to 2024 for 100 miles will reduce to almost 7.7 minutes. In contrast, StoreDot’s silicone-dominant anode technology will go down to just 5 minutes in 2024 at 6.3C. Another leap in the battery performance world will be the introduction of the “100in3” energy density pack in 2028. It will be further reduced from 3 minutes by the introduction of “100in2” in 2032.
100 Miles – 2 Minutes – 10 Years
In StoreDot’s 10-year outlook they plan to achieve a slow-charge energy density of 700Wh/kg in a pack with a capacity of 160kWh by 2032. The changes StoreDot is planning will include 100×2, which would cut the charge time in half compared to other industry leaders.
Along with these plans they will address consumers’ concerns by getting their battery to offer 990 miles of range for an EV. We need overall advancements in the EV ecosystem for all these updates and developments to matter.
A Joint Effort
Undoubtedly chemistry and design of the battery back have a huge role in deciding the time a battery charges. External factors like the efficiency of the charge station and the current capacity of the plug all increase consumer experience. These will help in the global adoption of electric vehicles.
The CCS – Combined Charging System for Level 3 DC- Charging supports a maximum of 400A for 400kW at 1,000V. Some companies make these CCS chargers which give an output of a maximum of 500A. Companies are coming together to beat this number. China’s State Grid and Japanese CHAdeMO Association are working to increase it to 900KW at 1500V and 600A.
The thing to note as we upgrade this charging levels is that the entire infrastructure will need updates as well, such as transformers and cables. There will be cases where we need solutions such as renewable energy and hydrogen fuel cells with battery storage, coupled with bi-directional smart-charging and billing. The final step is making the EV design energy-efficient. It depends on many factors which include aerodynamics, weight and size of the car and engineers being able to create efficient motors and control systems. .
Battery Technology published that the EVs which were in the low-mid 200Wh/mi range were the most efficient, while those above 300Wh/mi were the least efficient. As the EV industry is progresses by leaps and bounds, we need a transformational product to overcome the barriers faced in the adoption of EVs. A “Range on Demand” user experience is required. To introduce the fast-charging battery we will need make sure there is a realistic and clear plan put in place StoreDot’s “100inX” offers that vision in an easy format to understand as we move forward.
