Electrovaya to Supply Battery Pack for Raser Plug-in Hybrid Demonstrator Vehicle

Raser Technologies is ordering an Electrovaya Lithium Ion SuperPolymer integrated battery system for use in its plug-in hybrid demonstrator vehicle. (Earlier post.)

Electrovaya will provide its batteries, integrated intelligent battery management system and engineering support for integrating complex power systems. Program leader, Raser Technologies, will incorporate its Symetron electric motor and power electronic drive powertrain technology. FEV Engine Technology, Inc. will integrate the vehicle.

Electrovaya currently offers three chemistry solutions for its polymer battery platform, which is independent of electrode materials:

  • Cobaltate (150-220 Wh/kg) for small systems, i.e. cells up to 10 Ah;

  • Phosphate (110-130 Wh/kg), a lithium iron phosphate electrode material for large systems including transportation; and

  • The recently introduced MN-Series (170-210 Wh/kg), a lithiated manganese oxide based system. The MN series offers up to 50% higher energy density with comparable safety and rate properties to Electrovaya’s Phosphate-Series chemistry, and is the company’s preferred chemistry for transportation. (Earlier post.)

In August, Electrovaya delivered its first plug-in hybrid Ford Escape—based on the MN-series—to the State of New York. The increased volumetric efficiency of the MN-Series enabled the near doubling of the capacity of the pack to nearly 15 kWh.

Electrovaya has previously collaborated with Raser Technologies as co-founder of the Plug-in Hybrid Consortium with the aim of accelerating plug-in hybrid commercialization.

At EVS-23, Electrovaya is highlighting its upgraded Version-3 intelligent Battery Management System (iBMS) for transportation applications. The iBMS has been designed for 15V and 48V modules which may be integrated to form intelligent Battery Systems from 48V to 710V.

The iBMS is an integrated, CAN-bus solution with fail-safe capabilities. It optimizes the battery system for optimal performance at a cell and module-level, protects the system and provides system-level interface communications to optimize the battery system together with other elements such as motor, controller and charger.

The iBMS consists of both distributed and system control intelligence integrated in the battery system design. It is available in several voltage configurations and is available as an integrated solution for all three of Electrovaya’s chemistry offerings.



That MN-series at 200 Wh/kg is a complete game changer if it really has the safety, cycle and calender profile to compete with Altair etc.

The lattest MN-Series version energy density is supposed to reach 330 Wh/kg. This would make it one of the best EESU for PHEVs, specially when coupled with very high efficiency motors such as those developed by Raser Technologies.

A very interesting joint venture.


Both are pretty high performers.


330Wh/kg? Nice!

I wish them the best.


How can a polymer battery be used in a car? Aren't the rates too low?


"Electrovaya’s zero emission vehicle, the MAYA-100 is powered by energy-dense, lithium-ion SuperPolymer® technology. Equipped with a 35 to 50 kWh battery pack, this long-range ZEV can travel over 200 miles between charging."

It seems that they can be used for EVs.


I'm all for whatever Raser does. I would consider Enerdel to be a strong competitor in the Li-ion battery for Hybrid and electrical vehicals. If interested take a look at this site. They are 80% owned by Ener1 ticker ENEI .
