Exro Technologies Inc T.EXRO

Alternate Symbol(s):  EXROF | T.EXRO.WT | T.EXRO.WT.A

Exro Technologies Inc. is a clean technology company. The Company is engaged in developing power control electronics that expand the capabilities of electric motors and batteries. Its technologies include e-mobility (Coil Driver) and stationary energy storage (Cell Driver). The Coil Drive technology is an adaptive traction inverter that replaces the standard 3-phase inverter in electric vehicles. Utilizing its patented coil switching technology, the Coil Driver enables the motor to dynamically switch between two modes, series mode optimized for high torque at low speeds, and parallel mode optimized for high power and efficiency at high speeds. The Cell Driver technology is a fully integrated energy storage system designed for commercial and industrial applications. Its SEA-Drive power system provides a complete e-propulsion solution to original equipment manufacturers. It encompasses everything from high-capacity batteries and electric motors to next-generation control units.

RE:RE:RE:Keep this in Mind
I don't believe that the latest patent necessarily combines the coil driver and the cell driver.
 
What the BCS offers, based on my understanding, is two things.
 
First, it offers a novel capability to identify and isolate low capacity cells, and then "undiverge" these into threads of similar abnormal cells  This can lead to increased safty, efficiency and longer life.  
 
The patent, or a related patent,  also offers a new method for driving storage cells by ac, which I don't understand.  This negates the requirement for an inverter in stationary ESS (Eric). It can lead to 2X battery life in EVs. 
 
The newest collaboration appears to be focused on increasing continuous power and torque, and not battery life.  LFP batteries are expected to have considerably longer life than the alternative.  Newer lithium manganese iron phospate batteries potentially could last up to 2 million kms (Electric Viking). This certainly introduces a new paradigm regarding the importance of extended battery life. 
 
There is a video of Eric explaining the cell driver technology.  I believe that this previously has been posted.  Worth a view if you haven't already seen it.
 

From EXRO's latest NR:
 
"A world leading global automotive OEM has engaged Exro in a collaboration to explore the latest advancements in power electronics technology to deliver higher continuous power and torque output compared to conventional systems."
 
Mercedes fits this bill.  It is looking at smaller, more power dense axial flux motors in some of its future cars.   It bought axial-flux motors specialist YASA for this purpose. If I understood Eric correctly in his prior media session, this is one of the motors that could benefit from the dual torque/speed profile of a CD. And it can reduce the requirement for rare earth metals.  The space restriction could be related to hub motors.  Don't know.
 
Some of the vehicles that Mercedes is looking at include:
 
 
 
And if you  include hybrids:
 
 
I'm not suggesting that Mercedes is the collaborator.  Just an example of one of the possibilities.  Whatever it is, I belieive that it will be in the premium/luxury/performance vehicle space.  The next wave.
 
I appreciated the conversation Exronly.  I'm always keen on learning.
