1Carmakers from the United States and other countries are thinking about ways to manufacture and improve a technology called an e-axle or e-drive.
2This technology is fast becoming an area of competition in the automobile industry.
3The e-axle, or e-drive, joins an electric vehicle's gear, motor, and power-control electronics.
4It is the "brain" that controls how a vehicle uses energy stored in its battery.
5This "brain" turns that energy into power.
6It also helps get back energy lost when stopping the vehicle.
7In other words, a well-designed e-axle increases a vehicle's power efficiency and ability to change speeds.
8It also helps extend the vehicle's driving range and its smoothness.
9The technology has become a competitive area, in part, because automakers are under pressure to cut electric vehicles' manufacturing costs.
10The goal is to make them cost as much as cars powered by gasoline.
11Progress in new technologies is also important for efforts to cut pollution, including carbon dioxide, also known as CO2.
12Vehicle-based CO2 emissions are responsible for about 17% of emissions from all sources, says Zifei Yang.
13She is with the International Council on Clean Transportation in Washington.
14Yang noted that the reduction in vehicle emissions has slowed as more people drive bigger, more polluting sports utility vehicles.
15Other industry experts point to changes in countries such as China and India, where more people are buying and using cars.
16In recent years, the Japanese business Nidec has turned its attention to automobiles and e-axles.
17Shigenobu Nagamori is the company's founder.
18Nagamori says he wants Nidec to control up to 35% of the world's e-axle market by the year 2030.
19That market could be worth $20- to 30-billion a year by then, up from an estimated $2.8 to $3 billion today.
20Nagamori has said he believes the way to become a market leader in e-axles is to reduce the cost for the technology.
21The way to do that, he said, is by being able to produce every part that goes into an e-drive system.
22Some automotive technology suppliers are working together to manufacture e-axle systems.
23Japan's Denso and Aisin formed a group called BluE Nexus in 2019.
24This year, U.S. parts supplier BorgeWarner agreed to purchase Britain-based Delphi, and Japan's Hitachi Automotive joined with three Honda group suppliers.
25Automakers Volkswagen, Ford, Toyota and smaller Japanese brands are each making technology groups in part to drive down e-axle manufacturing costs.
26Electric car maker Tesla developed its own e-axle technology.
27But it is unclear whether the company continues to use it in more recent Tesla models, noted Reuters news agency.
28General Motors, or GM, Nissan and some other carmakers believe e-axles offer such a large area for growth that they want to design and manufacture their own systems.
29GM believes it can better join the e-axle with the battery and the rest of the vehicle, making for a quieter, smoother and more economical drive, said the company's Adam Kwiatkowski.
