EV Study Reveals Impacts of Fast Charging

(1/1)

Found this link in a newsletter of a charger provider. That may ease some anxiousness about fast charging our bikes.

Apparently Tesla has built in enough safeguards to avoid damage of the battery by fast charging. Looking at the capacity numbers (max 21,5 kWh / nominal 18,9 kWh / real world approx. 16 kWh) I have no doubt that this applies to Energicas as well.

Specter:
Battery replacements under warranty get VERY expensive, so does making a customer have to buy one out of warranty, it gets VERY expensive reputation wise.  There is plenty of head room to make sure the batteries are kept safe and cozy.  Their software is fairly extensive to protect that HUGE investment in the overall bike, that the battery is.

This is apparent by the fact that it slows down when it's hot, when it's cold, when it's nearing the end of it's charge, when it's balancing, THAT it is balancing etc etc.

In theory slower is ALWAYS better, less of a percent cycle is ALWAYS better, but then the real world kicks in, ... at what expense?  How much are you willing to put up with?  How much are you willing to sacrifice?

If you charged them at 5 amps they'd last probably 10k cycles, but do you want to take 20 hours to charge the battery EVERY TIME?  No, so you trade off a little longevity for speed and convenience.

If you only cycled them 20 percent of their capacity they'd probably last 10k cycles or more, but do you want an effective range of only 40 miles?  NO, so you trade a little longevity for range, and convenience.

If you only pulled a 0.2 C rate off the battery it'd last a lot longer, but do you want to take 45 seconds to get up to 60 MPH, and have 60 MPH be your top speed, on a good day?  Again, no, we're not quite ready to join the Rasqual Roustabout gang yet :)

It's about  Compromise...
