Battery Capacity For Plug-In EVs Increased By 22.6% From 2014 To 2015

AUG 17 2016 BY ERIC LOVEDAY 12

Once a week, the U.S Department of Energy puts out its “Fact of the Week” and often times the fact is focused on plug-in electric cars.

Such is the case with the “Fact of the Week” release, focusing on the total batter capacity increase for plug-in electric vehicles in 2015″

TOTAL BATTERY CAPACITY OF ALL PLUG-IN ELECTRIC VEHICLES SOLD INCREASED FROM 2014 TO 2015

The number of battery packs sold for plug-in electric vehicles (PEV) declined by 3.4% from 2014 to 2015. However, the total battery capacity for all PEVs sold between 2014 and 2015 increased by 22.6%. The rising battery capacities of PEV models have increased battery production even when sales of battery packs are down. Following the introduction of mass market PEVs in 2011, the total battery capacity sold increased nearly tenfold from 0.4 to 3.8 million kW-hrs by 2015.

The sales volume of hybrid electric vehicles (HEV), and therefore HEV battery packs, is much higher than for PEVs but their battery capacities are much smaller. Battery capacities for 2011-2015 HEV models usually ranged from about 1 to 2 kW-hrs while PEV models for this same period had battery capacities as large as 90 kW-hrs for a single battery pack. As a result, the total battery capacity sold for PEVs is much higher than it is for HEVs despite lower PEV sales volumes.

In addition to the brief release, the DoE compiled a couple of nifty charts.

Given that 4,000 less PEV,HEVs were sold in 2015 over 2014, this fits. Will be nice to see both lines heading upwards in 2016

2014: 122,238 EVs sold with 0.4 million kWh
2015: 216,099 EVs sold with 3.8 million kWh

The number kWh (per EV) seems a bit low?

eg: in 2014: 30,000 LEAFs (24 kWh each) is 0.72 million kWh (exceeding 0.4 million kWh value)

eg: For 2015 the numbers seem closer …~17,000 LEAFs (24 kWh each) In 2015 is 0.4 million kWh; add in 25,000 Model S with 80+ kWh is 2 million kWh; 15,000 Volts, etc

You misread, the 0.4 million kWh is from 2011 not 2014

And much longer life than the warranties imply. In fact Hyundai gives a lifetime warranty of their hybrid and plugin hybrid batteries. I see 20-30 year life in ALL batteries with thermal control. So that only leaves 2 auto makers out of long life batteries.

Dorman Products already offers remanufactured hybrid battery packs, they offer three year warranties AND they offer higher capacity batteries with the remanufactured packs. If Ford won’t sell me a higher capacity pack when my pack gives out, out of warranty, I’ll try to get a higher capacity pack from companies like Dorman Products. I think the articles I’ve read about pack replacement not being practical are just ridiculous, especially if you can get a higher capacity remanufactured pack from a company like Dorman Products.

And Ford Energi answer to Chevy was to product a few percentage point of efficiency; sigh. I wonder if Dorman will have a higher capacity battery for the Energi. Ford really missed a chance to move the battery out of the trunk in 2017. I noticed they also slightly changed the headlights so previous models cannot use them.

This is what I want to know: Which is the PHEV with 90 kWh?!?

Seems like they have included trucks/buses..??

They talk about PEV models, not PHEV. That means both EV’s and PHEV’s. You can guess the car with 90 kWh.

That would be the Tesla P90

One interesting thing that you can see in the photo above that the size of the 60 kWh pack isn’t 3.25 bigger.
Increase in power density give room for better car design and better performance.

Ugh, almost meaningless math going on here. It is due to two things:
– higher sales of Teslas which raises the average.
– slightly higher capacity of Volts.

Extra credit:
– almost negligible sales of tiny battery Plug-in Prius

The problem is that PiEV – Plug in EVs do not all use the same battery pack. So, deltas in one brand can make the math look “interesting”.

What would be better is a “weight of battery packs dropped on a kWh stored per kg of weight”. that would be something to report on.
