Nissan Leaf 40 KWH Battery: Check Out The Subtle Differences Under The Hood

One sure way to tell that the green revolution has hit the car industry is when major automaker players start revamping the very models that responded to the need for more environmentally-friendly cars. Such is the case with Nissan, which not only did a major upgrade on its Leaf model, it also completed a massive overhaul of its battery.

For openers, that battery's got a heck of a lot more power, boasting a 40 kWh capacity, an increase of 25 percent over the last version. That will certainly help in achieving more distance without recharging, as in more than 150 miles if figures released by the Environment Protection Industry is any indication.

That said, you wouldn't be able to tell the difference between the current battery and its predecessor if you removed it from the Leaf. However, the folks at EVs Enhanced, a web blog for green energy car enthusiasts, did just that to provide its analysis on what makes the upgraded component so different.

A very attentive eye was required, since the frame, shell, pin connectors, modules and the battery management system appear to be very similar to the old leaf battery. Beyond that, the differences include the current sensors now have four wires instead of three. Those wires, which connect to the battery management system, accommodate two sensors instead of one, to better manage the calibration of the electric currents.

As well, the fuse has also been upgraded to withstand the 400 amps of power that's generated when the Leaf has the pedal to the metal. That same fuse, which used to be housed at the top of the battery, has also been relocated further inside the unit.

Those were the big points raised by the assessor, and despite some shaky camera work for an inspection that took roughly less than three minutes, might be enough to arouse the curiosity of green types.

But don't expect this upgrade to last very long, as the Nissan Leaf battery is reportedly being overhauled again for a 60 kWh battery in 2019 that will include a temperature management component which will likely be liquid based. That might make for a much different-looking battery.
