The Future of Electric Propulsion
We love answering questions about what we do! Questions are a sign of interest in our technology and there is nothing that excites us more than talking about than our technology. So below is a description that answers the few common questions about eDTS—the most revolutionary among our solutions—what it is and what it does. It’s adapted from a much longer paper, which you can download here, but if you need a shorter, condensed version, read on .
A variety of options among UAV power systems allows for more choices based on different mission parameters. UAVs can be either fully electric, powered by internal combustion engines (ICE), or operate in a hybrid mode, where the UAV power system works with ICE to provide electrical power to the aircraft when necessary.
Electric motor performance in UAVs is a critical part of their design. Weight, operating temperature, and electrical efficiency of the power components influence various parameters such as flight duration, payload, operating ceiling, and range. Electric motors and their design need to account for all the above and more.
The biggest consumers of electricity in the residential sector and in buildings overall are space heating and cooling, lighting, water heating, space heating, appliances, and electronics. In the commercial sector, this comes from lighting, heating, ventilation, and air conditioning. Finally, in manufacturing, more than half of electricity powers motors (machine drives), with other significant uses covering heating and cooling.
Dynamic Torque SwitchingTM (eDTSTM) is an innovative electric propulsion technology for a range of electric vehicles. It delivers a significant improvement in power efficiency and performance, which translates into a net reduction in vehicle cost through smaller battery packs, extended range, or a combination of the two.
Electric propulsion is not a new invention. The basic technology has been around for a long time, with the first electric vehicles built in the late 1800s and early 1900s. Its common and widespread adoption has been clearly delayed, but it’s finally gaining momentum.
We need to be honest. There is no such thing as a completely green car. It might run clean and produce no harmful emissions. But the way it’s manufactured and the impact its batteries have on the environment are certainly far from being perfectly green. Across their full life cycle, EVs are more environmentally friendly than their internal combustion engine (ICE) counterparts and, once they’re on the market, they will contribute significantly to a drop in carbon dioxide emissions. But to make them as green as possible, we need to make sure that:
The battery pack is the most expensive component of the entire electric vehicle. According to BloombergNEF, the average cost was $137/kWh at the end of 2020. Although the estimates can vary, averaging 30% of the total cost of the vehicle, even moderate savings to this component would have a huge impact on the overall cost of the car manufacture and price. However, more recent analyses predict that the prices will start going up again due to the rapidly growing demand for EVs.
