    On cell specifications and battery charging characteristics

    I'd like to see what the "true capcity" discharge curve looks like, if the one that's published is a derated one. To me it looks exactly the same as all other LMO cell curves (which are not derated). Let's close this disussion and wait for someone to actually do a 1/3C discharge of an actual...

    On cell specifications and battery charging characteristics

    Sigh! AndyH: to get the true maximum installed capacity of a battery pack (in Wh), you multiply the nominal cell voltage with the max cell capacity and then the total number of cells (regardless if they are in series or parallel). For the Leaf, this gives us 24kWh. The fact that we only use a...

    On cell specifications and battery charging characteristics

    Normally the cut-off voltage is 3V, not 2.5V as in the graphs. You really don't get any more energy out from 3V to 2.5V. Note how the capacity slightly increases between 1C and 1/3C rate. The rated capacity of 33.1Ah is very close to the maximum Ah you can extract from the cell, so total...

    On cell specifications and battery charging characteristics

    You can find the detailed cell specifications at http://www.eco-aesc-lb.com/en/product.html Leaf uses the 33.1Ah cell, two in parallel, and 96 in series (192 total). Nominal pack voltage is then 360V, and total installed capacity is 192*33.1*3.8/1000 = 24.15kWh. This should end all...
