FAST CHARGING : IP LANDSCAPE REPORT

1 FAST CHARGING : IP LANDSCAPE REPORT Introduction 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. Electric vehicles have two different charging methods - an alternating current (AC) on-board charger (both slow and fast charging) and a direct current (DC) off-board charger (for fast charging). Charging an electric vehicle off an AC wall box takes about eight hours. When on the road, EVs can be charged using either AC charge posts or DC fast chargers, depending on the type of car and the availability of time. Among the EV fast charging networks, Tesla s Supercharger network is the most popular. Other players in Europe as well as auto majors like BMW, Daimler, Ford, Volkswagen, Audi and Porsche, are working to come up with ultrafast EV charging networks of their own. [1] 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. Phone manufacturers have come up with their own standards for fast charging. [1] 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$ Billion by 2022, growing at a CAGR of 29.8% between 2016 and [2] This IP landscape report provides insights into the currently active patents addressing various technologies and applications related to the fast charging of batteries.
