Recharged: Secondary Use of Electrified Vehicle Batteries
Global moves to tighten regulations for CO2 emissions have triggered a full-scale drive towards electrified automotive
powertrains. Particularly worth noting has been the advancement of batteries, which may present a major bottleneck in
determining the driving performance and affordability of an electrified vehicle.
The cost of batteries currently affects the affordability of hybrid and electrified vehicles (HEV/EV) for end consumers.
While batteries degraded to 70%-80% of their original power are considered insufficient for their primary automotive
use, these partially depleted batteries may still be useful and could be reused in other applications. Such secondary-use
applications could significantly increase the total lifetime value of the battery, and thus reduce its cost to the initial
automotive user and battery owner.
Possible secondary uses for lithium-ion (Li-ion) batteries include lower-grade automotive and mobile applications;
residential and commercial electric power management; power grid stabilization to help provide reliable electricity to
users; and renewable energy system firming, which in this case involves using batteries to stabilize and store power
provided to the grid by variable resources such as wind and solar energy.
Standardization will be a key enabling factor going forward to allow maximum potential for compatibility in the re-use
for packaging and other versatile applications.
Allocating used electrified vehicle batteries to secondary-use applications also could benefit the environment by
delaying the recycling or disposing of batteries, and by supplying a service that improves the efficiency and cleanliness of
other industries.
Using its expertise acquired through numerous HEV/EV projects, P3 North America has developed a purposeful plan for
the secondary-usage of batteries. Findings are separated into two categories, stationary and mobile, creating a more
sustainable and clear future for HEV/EV manufactures, as well as the vehicles they produce.
Arthur Holland from P3 will be speaking on this topic during The Battery Show. An expert in batteries, quality and
engineering processing, he is also Chairman of the SAE Committee for Secondary Battery Use.
In addition, P3 has published a white paper with further details on this topic. Contact us if you are interested in a copy.
P3 North America, Inc. is a member of the P3 Group, a global firm with over 1,400 consultants. Headquartered in Troy,
MI, P3 North America was founded in 2005 with the objective to serve a growing client base in the automotive and
aviation industry, defining and implementing concepts and solutions in an engineering and operational environment.
P3 specializes in strategy consulting, process and project management and offers highly sophisticated engineering
solutions. In the automotive industry, OEMs and suppliers appreciate expertise along the entire value chain from
strategic planning, product development, procurement and production, to aftersales and marketing.
By providing viable and cost efficient secondary-use options for the HEV/EV vehicle market, P3 can provide a way to
reduce costs. In the fully equipped test laboratory, the specialists at P3NA check battery cells under all standard test
conditions, under real load profiles or specially defined test conditions. They provide support on all matters related to
lithium-ion batteries and lead batteries for mobile and stationary applications. Their range of services includes lithiumion batteries, lead batteries, supercaps and commercial cell chemistry.
P3's test laboratory includes several hundred testing circuits for individual cells in the range from 6/18/60 volts as well
as for cell stacks up to 800 volts. These are loaded with currents of up to 1500 Amps or treated in temperature
chambers. To gather data on the electrical performance capability and service life of battery modules and battery packs,
we have at our disposal a shaker for batteries up to 50 kg, as well as six testing circuits. These have performances of 80
kW (500 V/400 A) and 240 kW (maximum 800 V/600 A).
Developed and parameterized for optimized battery systems, P3 on-board diagnostic procedures forecast the expected
service life in the field as well as electrical and thermal service life models.
