German vehicle-maker Audi is in the middle of testing a 48V lithium-ion system for full electric and mild-hybrid vehicles.
The prototype system allows the battery to offer 0.5 kWhs and a peak output of 13 kW through the use of electromechanical rotary dampers to harness regenerative breaking energy.
One of China’s largest lead-acid battery manufacturers has opened a factory to make start-stop batteries that it will supply directly to OEM firms such as Audi, BMW, Mercedes and Volkswagen.
The factory, in Boading in the Hebei province, China, has an annual capacity of five million batteries.
German carmaker Audi is to introduce a dual 12V/48V electrical architecture to future ICE (internal combustion engine) vehicles.
The 48V system features a lithium-ion battery and a DC/DC converter to integrate the 12V electrical system. The alternator achieves an energy recovery output of 10kW, adding up to a saving of up to 10g/km CO2, according to Audi.
Korean battery maker LG Chem has struck a deal with German automaker Audi to supply lithium-ion batteries for its next generation hybrid vehicles.
The 48V batteries will be used in Audi’s new plug-in hybrid and micro-hybrid vehicles. The lithium-ion batteries are to replace currently integrated 12V lead-acid batteries.
