Penn State team develops thermally modulated LFP battery; fast-charging, inexpensive, long-life for mass-market EVs

Green Car Congress

A team of Penn State engineers has demonstrated a thermally modulated lithium iron phosphate (LFP) battery to offer an adequate cruise range per charge that is extendable by a 10-minute recharge in all climates, essentially guaranteeing EVs that are free of range anxiety. —Professor Chao-Yang Wang, corresponding author.

MAHLE Powertrain presents new prototype 48-volt battery for mild-hybrid vehicles

Green Car Congress

Thus a compact and cost-effective battery that is capable of high charge and discharge power levels relative to its storage capacity (high C rates) is desirable. As there were no suitable low-cost, compact batteries able to deal with the necessary recharge and discharge cycles involving high currents, MAHLE Powertrain developed its own.

Bosch sees future requiring multiple powertrain technologies; the larger the vehicle, the more the electrification

Green Car Congress

In order to further reduce its CO 2 emissions in this vehicle class, the gasoline engine will require a low-cost, basic hybrid solution. This will be done with a broad range of efficiency-enhancing technologies, including the turbocharging of downsized engines. Automating the manual transmission, for example with the eClutch.

NREL Study Finds That A Dynamic Plug-in Vehicle Could Be A Promising Technology Pathway for Cost-Effective Vehicle Electrification

Green Car Congress

The study by Aaron Brooker, Matthew Thorton and John Rugh aimed to identify possible pathways to cost-effective vehicle electrification by evaluating a variety of scenarios and technology improvements. Even so, they found, extra battery costs in PHEVs and EVs outweighed the gasoline cost savings.
