    Charging Sessions and Charging Voltage

    The number of charging sessions for an EV's battery pack, regardless of your SoC and routine charging limit, have affect on battery life. Can we discuss this issue in light of Tesla recommendations to Plug in to a TWC every night? Why to avoid high powered DC chargers for your routine charging...

    Ex-Tesla Engineer Says Solid-State Batteries Are A 'False Hope'

    Now at the helm of Sila Nanotechnologies, he believes lithium-ion cells will reach $50/kWh in ten years. The whole world currently bets solid-state batteries will be a revolution in energy storage. Some bet even their own money on that, such as Volkswagen and Bill Gates are doing with...

    lithium-Ion explosion

    Hello I am interested in how does Tesla prevents the battery from exploding while exposed to the heat in some states. From my experience, you can't put those batteries outside for a long period of times. This is even true for power banks who has small batteries. Can someone explains how does...

    Battery 101: 40 000 cycles with Panasonic 18650 cells?

    Electrical Engineer, Frank Boucher, just wrote an interesting and easy to understand technical article about Panasonic NCR18650B Cells. He also explains why a EV battery pack will be good for much more than 500 cycles, but up to 40 000 cycles (by keeping the pack between 30% and 70% SOC). That...

    How much has your Model S' battery degraded?

    My 2013 Tesla P85 (6,500 miles) now has a range of 204 miles at about 85% charge - the loaner I just had (also a P85) had a range of about 220 at 85%, yet it has 2,000+ more miles than my car and it was newer. I thought lithium ion degradation was related to how many times the cells were charged...
