Global Mild-hybrid Vehicles Market - Growth, Trends, and Forecast (2018 - 2023)
The prospects for the market have started attracting a lot of automotive technology vendors to the market. The global mid-hybrid vehicles market is expected to register a CAGR of close to 7% during the forecast period.
Controlled Power Technologies
Controlled Power Technologies (CPT), one of the pioneers in providing environment-friendly automotive technologies, had shown great interest in 48V mild-hybrid vehicles. It has planned to launch switched-reluctance (SR) motor-generator technology for these vehicles. The company has also shown interest in developing a portfolio of electronically controlled electrical machines known as COBRA, Speed Start, and TIGERS suited for these vehicles. The product is expected to bring about significant CO2 and NO2 reduction through different applications of switched-reluctance technology, which is also helpful as it eliminates the need for permanent magnets and earth metals in an electrical machine.
Evolution of vehicle emission regulations will result in difficulty in meeting the standards with the conventional vehicle technology. Also, a shift to the fully hybrid and pure electric powertrains involves a considerable cost in building different infrastructural platforms. Thereby, an intermediate technology like that of mild-hybrid is a very effective development where the vehicle has the capacity to incrementally improve fuel efficiency from the traditional powertrains. A significant amount of braking energy can be regenerated in this system. The alternator is replaced with a reversible 48 V electric machine with a large battery. Mild-hybrids make use of stop-start and regenerative braking but they tend not to return as high an EPA-rated mpg as full hybrids or electric vehicles.
The electric machine provides the much-required torque boost and assists in the considerable downsizing of the internal combustion engine. The improvements and developments permit the 48V mild-hybrid to have increased acceleration, noiseless start-stop and smooth take-off that would significantly improve driver experiences, almost replicating the advantages of hybrids at less than half the cost and structure. Some common examples of these vehicles are General Motors eAssist and Honda’s Integrated Motor Assist.
The Mercedes mild-hybrid system is a mainstream hybrid system that uses a lithium-ion battery. In 2010, GM launched a second-generation version of its mild-hybrid. The newer version increased the motor power from 5 to 15 kW and the earlier nickel metal hydride battery was replaced with a higher capacity, lighter lithium-ion unit.
The main challenge faced by the OEMs as of now is putting forward a portfolio of electrified vehicles that not only satisfy the regulatory requirements but are also acceptable to the customer at a cost effective bargain. Compared with 200V to 600V full hybrid and pure electric vehicles, the low voltage mild-hybrid approach eliminates the need for high-cost safety features and large battery packs. In addition, the universal application of the mild-hybrid technology in more than 100 million gasoline and diesel engine vehicles per annum to be produced during the forecast period is expected to reduce annual CO2 emissions by more than 100 million tons globally per annum.Major Players: AUDI, BMW, HONDA, MERCEDES, NISSAN, PEUGEOT, amongst others
