One more chance, maybe the last chance, for mild hybrids to proliferate. Wayne Gerdes – CleanMPG – Nov. 23, 2017 Bosch’s new 48V battery for mild hybrids will soon be reaching automakers across the globe. OEMs can also eliminate the expensive R&D to create a similar system from scratch. This means that installation of the Li-Ion battery and small but robust motor will benefit compact through microcars. Production of the battery is scheduled to start in late 2018. Anticipating a large market for entry-level mild hybrids, Bosch offers other powertrain components for these models in addition to the 48V. The company estimates that some 15 million 48V hybrid vehicles will be on the road by 2025. Automakers in China, Europe, and North America are focusing on CO2 emission reductions. According to Bosch, the yet to be produced 48V battery is already in high demand among Chinese manufacturers, and the Li-Ion unit is poised to become a global success. Bosch is already in talks with over a dozen customers and has secured a considerable number of production projects. The secret of the battery’s success is its inexpensive way to reduce vehicle CO2 emissions. The battery requires no active cooling and its housing is made of plastic, not metal. Both bring costs down. The plastic housing presents a challenge, as Li-Ion cells expand when the battery is charging and over the course of the battery life. As a result, the housing must withstand a certain amount of stress. Bosch. invests $475 million USD/year in electromobility with more than 30 production projects, including in the manufacture of batteries, that are in current production. The affordable 48V hybrid for the mass market provides the ability for every powertrain to become a hybrid drivetrain. Bosch expects its battery to find success in not just China but Japan and Europe as well. Bosch 48V Li-Ion Q&A How does a 48-volt hybrid save on fuel? A 48V hybrid can reduce fuel consumption through the use of a regenerative braking system that stores and then doles it out to a small motor to help accelerate the car back up to speed. Why is China seen as an e-mobility pioneer? With more than half a million models sold, China is by far the world’s largest market for electric vehicles. It is a world leader in e-vehicle production, too. Electric vehicles and hybrids are set to take over still more of the Chinese market, especially with government support. Why is the new battery efficient when it comes to CO2? No other country in the world emits as much CO2 into the atmosphere as China. It has set itself a fleet target of 117 g/km by 2021, and China’s automakers are looking to the 48-volt hybrid system to help them achieve this goal. Bosch’s new and less expensive 48-volt battery will make the system more affordable for a broader market, and will thus help Chinese automakers considerably reduce CO2 emissions. I just do not see the market for a 48V system when 250 to 650V systems use mostly the same components albeit larger in every respect and offer far superior efficiency gains. There are savings in the downsized components but is Bosch reinventing the wheel with a smaller wheel and trying to gain something from it? Then again, a mild hybridized drivetrain is certainly more efficient than one that is not hybridized at all?
