Batteries and battery technology have evolved a lot over time. Batteries today, power everything from cars to satellites and are a source of emergency power as well. The rechargeable kind are near ubiquitous in the many electronic devices we use daily. A couple of variables remain key in connection with rechargeable batteries – the time taken to fully charge them and the duration they can provide power for when fully charged. We focus on the first of these aspects in this report.
Fast charging technologies are being increasingly used to cut down the charging time for electric vehicles (EV) and various consumer electronic devices. Superfast charging is a critical feature that drivers look for when purchasing an electric vehicle. In the latest smartphones and laptops, fast charging is made available through a compatible USB-C cable and adapter that can fully charge these devices in less than an hour.
There are some estimates available for the different segments of the battery charging market. For example, the electric vehicle charging stations market is estimated to reach US$ 12.61 Billion by 2022, growing at a CAGR of 29.8% between 2016 and 2022. This IP landscape report provides insights into the currently active patents addressing various technologies and applications related to the fast charging of batteries.
They have at least adjusted the pace due to Tesla. The rest is due to better batteries, and that a useful EV could be made. VW made their first EV back in 1976, with lead acid batteries.. was a test car for 10 years. Testing motors and batteries. In 1989 they released the first electric Golf available to the public, this time with lead-gel batteries in the floor of the trunk. 30 miles range. Then came an electric Jetta with sodium-sulfur batteries, and 74 miles range. In 1993 they released the electric Golf 3. First VW with AC motor, lead-gel batteries, break regen, 55 miles range. Charge time was 2 hours to 100%. . and so on. Slowly learning, low production numbers. In 2007, they shower the first e-up prototype. A year later Tesla released their first EV. The newer models like VW e-up in 2011 was the first with “volume production that used lithium ion batteries. Since then it”s been step by step. Later this year, they will release the first of their from the ground up designed EVs, an AUDI.
