According to a report in The Telegraph this week, Volkswagen is bench testing a new battery with an undisclosed chemistry although it is believe it will be lithium-ion based.
While this news is very exciting for the potential mass adoption of EVs, the article as written is slightly ambiguous. It claims the battery will be able to provide ‘three or four times the power’ of existing batteries but then muddies this by stating capacities of up to 80kWh.
Reading between the lines, it seems to us that VW is testing a new, more energy-dense battery chemistry to allow them to store more energy within the same physical space. Possibly a real-world application of lithium-air technology.
The information provided comes from Dr Heinz-Jakob Neusser, the VW board member responsible for this development. He went on to comment that he believe that most people – in their second car – will be happy with an all-electric range of about 124 miles. For their main car, or only car, he is reported to say that a battery would need to provide a much greater range.
Also reported by The Telegraph is the news that Neusser confirmed VW has moved away from their high-temperature phosphoric acid fuel cell technology toward a more usual water/hydrogen cell.
Could this be an indication that VW is on the same page as Tesla when it comes to EVs and range? What does this mean for the just released e-Up! and e-Golf?
