Ford and Purdue developing charging station cable that can deliver increased current for faster charging

Green Car Congress

Ford and Purdue University researchers are working to develop a new, patent-pending charging station cable that could combine with in-development vehicle charging technology, making it even easier for people to transition to EVs with seamless re-charging. —Issam Mudawar, Betty Ruth and Milton B.

APRA-E awards WUSTL $2M to develop predictive battery management system for plug-in vehicles; targeting more efficient use

Green Car Congress

The system will predict optimal charge and discharge of the battery in real-time, enhancing battery performance and improving battery safety, charge-rate, and usable capacity. If Li-ion batteries are charged too quickly, they can heat up and may explode. Earlier post , earlier post.). Earlier post , earlier post.).

Paul Scherrer Institute and Toyota RD team finds tiny memory effect in Li-ion batteries; implications for vehicle battery management systems

Green Car Congress

The memory effect of the battery is written in a cycle with partial charging (here, 50% of the battery’s storage capacity) followed by complete discharge. In the subsequent cycle, the memory effect is evident through an overvoltage (small “bump”) at precisely the same point at which the partial charging cycle terminates.

Toyota RAV4 EV key for meeting California ZEV requirements; Tesla powertrain uses Model S components

Green Car Congress

and I think this will give us a good idea of overall consumer acceptance of EVs. Twenty-two months after the project announcement, Toyota and Tesla engineers revealed the RAV4 EV at Electric Vehicle Symposium 26 in May 2012. kWh of useable energy at full charge. The RAV4 EV has two charge modes: Standard and Extended.
