MK2 LEAF Battery and Drive train photos

Fri Dec 14, 2012 2:50 pm

Here are some closeup photos of the Mk2 LEAF battery that I took on my visit to Nissan Headquarters. Note that Mk1 batteries will be in a grey enclosure and Mk2 batteries will be in a black enclosure. Also notice how each module is open to the air so that each cell can better radiate heat.

As reported earlier this new battery pack key features are cost and weight reduction.

Thanks. I really like those pictures at the bottom showing the battery and drive train of the new LEAF! Having the charger upfront sure makes the layout more simple.

I'm having trouble correlating the last two mockups with the PowerDelivery/Inverter/Motor photos above them. Is the box on the top of the last two supposed to be the charger? And are we seeing the Power Delivery Module with the Inverter removed? Is the flat box on the back perhaps the DC/DC converter? Or is that integrated into the Power Delivery Module? Regen was formerly handled by the Inverter. Will it also be done by the Power Delivery Module?

The motor is on the bottom, the inverter is the gray assembly in the middle, and the power delivery module on top has the charger in it.

Regen is always integral with the inverter. In fact, there is no extra hardware needed/used, it's all just a software thing.

The components are the PDM on top, which contains the OBC, DC-DC, and HV DC distribution. The Inverter is in the middle, and the motor is on the bottom.

It's really no different than before, except the OBC is crammed into the HV DC block that used to sit behind the inverter on the MK1, and then moved on top.

Wait! Where's the valve cover?! :?:

Are you saying when you open the hood of a 2013 LEAF it won't look like there is an ICE in there? But I've just gotten good at explaining Nissan's "optical illusion" to people! ;)

Don't worry, the top of the PDM looks valve coverish enough to me.

planet4ever: I agree with you that the last two images of the OP do not match the others -- they look more like a prototype even before MK1!

Yes, it's interesting that the vehicle rolling chassis demo shows a very different packaging for the electronics and motor that the closeup of the drive-line package itself... I'm assuming that whomever did the chassis did not know the actual details of the components and thus just used a generic box and layout for them...
