ElectronVault launches cloud-based rapid prototyping tool for traction batteries

13 May 2012

ElectronVault Inc., an energy storage startup co-founded and led by Rob Ferber, a former Science Director at Tesla Motors who worked on the Tesla Roadster battery system, has launched a new cloud-based service for traction battery design for electric vehicle manufacturers. The new service is intended to reduce the time spent on traction battery system specification and production prototyping from many months to a few minutes, according to the company.

Once a system has been prototyped using Traction Battery Designer, manufacturers can expect a turnaround of 30 to 60 days for delivery of production units built to their specifications using the recently announced ElectronVault Series 1 line of traction battery modules, according to the company.

An addition to the company’s customized battery system solutions, the Series 1 line boosts battery energy utilization by 50%, extending range, power, and performance of electric vehicles, according to the company. The product line comprises four standardized module sizes, with more than 300,000 electrical configurations and battery cell load options that can be quickly delivered for easy integration into a range of electric vehicles from two-wheeled vehicles and automobiles to buses and trucks.

The company supports an range of chemistries; cell joining technologies are a core in the ElectronVault Battery System Platform portfolio. Safety and thermal management functions are inherent to the cell–cell joining layer providing electrical interconnection and current balancing. In addition, the company says, its universal BMS (battery management system) enables a high degree of fault tolerance and flexibility.

Manufacturers of personal mobility devices can opt for Size 1 (CL3) modules, which each provide 550 W of continuous power in a 6 kg, 221-millimeter-long package. Companies producing electric buses can opt for Size 4 (CL3) modules for 2200 W of continuous power in a 14 kg, 700-millimeter-long casing. All systems are shippable by common carrier for rapid integration into electric vehicle manufacturing processes.

Electric vehicle manufacturers can also mix and match different modules of the Series 1 traction battery line. Systems are deliverable in 30 to 60 days, or to suit development timelines.

Traction Battery Designer provides electric vehicle manufacturers with complete specifications, cost calculations and delivery dates for production-ready traction battery systems. The application tailors battery traction systems to the operating parameters and constraints of particular vehicle development programs. To make the application available for a select group of manufacturers, ElectronVault is launching an early access program later this month, with general availability for global vehicle OEMs slated for July 2012.

In order to speed past carbon-based transportation, the electric vehicle industry needs advanced solutions now. Traction Battery Designer will significantly cut product lead times and development costs. Our traction battery systems are designed for rapid deployment in the most demanding situations. And, by simplifying bill of materials and delivering high-yield processes, we cut manufacturing costs by up to 50 percent.

—Linda Maepa, COO and co-founder of ElectronVault

Using Traction Battery Designer, automotive designers can enter requirements such as vehicle weight, maximum speed and range, as well as controller operating parameters and limits to define a block diagram that describes the vehicle platform. The application then makes traction battery suggestions that leverage ElectronVault’s flexible Series 1 traction battery product line.

Designers have the option to refine the characteristics of any traction battery, or define several variations, so the solutions meet the business and engineering requirements of the vehicle OEM. Users can also view complete specification sheets, which include unit cost and delivery lead times for budget and planning.

Our traction battery systems have been proven to double energy storage utilization and increase vehicle range by as much as 43 percent in some applications. Using Traction Battery Designer, our customers can gain these advantages quickly and tackle market opportunities faster.

—Rob Ferber

ElectronVault’s launch market is the two-wheel electric vehicle market in Asia, which currently has more than 100 million electric two-wheelers on the road.

A fully modular mass produced plug-in battery approach would be one of the best way to reduce battery packs price while maintaining essential size, performance and flexibility.

It would be important to be able to add more plug-in modules, on an as required basis or as people can afford. On board diagnostic could easily identify which module is going down in performance and has to be changed.

Future electrified vehicles should be designed to ease battery module changes and/or adding more modules by users.

Designing EVs so that additional batteries could be rented for trips might make sense. Own a 80 mile range EV, rent an extra 80.

That would reduce cost and 'normal' weight.

Yes BW...and those with installed solar panels could use spare EV batteries for their solar power system? It should be easy to transfer energy (DC-DC) from one pack to another and be most free from the grid for EV energy. Surplus energy, if any, could be sold to the grid?

With enough homes so equipped, USA could eventually close down many coal fired power stations, crude refineries and gas stations. There is an interesting future potential to reduce crude oil imports.

Speaking of traction batteries, what happened to the KOLIBRI lithium-metal-polymer battery?

A Google yields ~nothing new in a year for a li-ion battery certified by German Engineering(gov labs) as having around twice the present li-ion battery energy density.

What is true on internet sites?

Do these modules also have a built-in Battery Management System?.. if they did that would really speed up design. Packaging the cells in a Volt is 30% of the total cost of the battery, but that includes a liquid cooling system.

Artemis hydraulic hybrid technology along with INNAS NOAX free piston hydraulic pumps can cut fuel use to one half or less with the same or better performance. Hydraulic gas pressure accumulators have better power and energy storage than ultra capacitors and much better power than many batteries. Just as seat belts and airbags were mandated in many places, hydraulic hybrids should be mandated.

Even existing lead batteries can provide enough energy for most automotive trips. Electric "HUMMERS" including the TESLA and TH!NK are not needed to reduce energy use.

There is very little use in the automotive for electric vehicles of high price.

Ammonia is a zero emissions concentrated liquid fuel, and perhaps someone will invent a anti-fuel cell that produces ammonia directly from air and water and electricity. ..HG..

@Herm: Yes, ElectronVault battery modules have fully integrated battery management systems (BMS). In fact, we fully integrate multiple layers of safety, electrical and thermal management which operate independently of yet synergistically with one another. Our BMS is one such component, allowing for safety and electrical management of individual battery modules but also at the battery system level.

This enables a fault tolerant battery system which can accumulate failed components while preserving 95%+ performance levels. We were guided by the principle that battery maintenance should not cost more, take more time, nor take place more often than periodic maintenance such as an oil or spark plug change.

Let's see oil is changed every 3,000 miles does that mean one is now expected to do battery maintenance at the same intervals? What value is there in that particularly for a car which is twice as expensive even with Federal subsidies?

"There is an interesting future potential to reduce crude oil imports."

Yes indeed the oil imports will be exchanged by lithium and rare earth imports from China and/or South America. From the frying pan into the fire. Good night and good luck!
