New version of PowerModule (v2) launched !

Posted on by Content Team

PowerTech is pleased to announce the launch of the new version of the PowerModule modular battery system. This product completes the PowerRack range for medium to high power applications.

PowerModule by PowerTech Systems

The design of the product has been engineered to reduce space requirements and facilitate integration.
The vertical and horizontal assembly of the modules allows a large number of combinations and meets a maximum of needs (Vehicles, marine, industrial machinery, rail, robotics, etc.)

Watch a one minute video presentation of new PowerModule :

This new version brings its share of new features:

  • “Plug-and-Play” and flexible system : Easy and fast commissioning
  • Scalable system : Serial and/or Parallel assembly up to 128 modules to fullfill the most complex appplications
  • Embedded Cell heating system for sub 0°C operations
  • Stainless steel housing with waterproof connection (IP67)
  • BMSMatrix® Technology inside
  • Serial assembly range from 51.2V to 819.2V nominal
  • Energy range from 5.4kWh to 688kWh
  • Safe and high performance Lithium Iron Phosphate (LiFePo4) technology
  • Minimum 3000 cycles at 100% DOD (at 1C)
  • External communication via CAN bus 2B
  • Full Monitoring over the cloud

New high-performance lithium LiFePO4 cells

Posted on by Content Team
Lithium Iron Phosphate - LFP - LiFePO4-cell

After more than a year of intensive testing, we are now using a new high-performance lithium LiFePO4 cells to replace the cells used in our products.

This new generation of cell retains all the safety and robustness of those used in our products to date and adds two major improvements:

  • Specific Energy improved by 25% : It is possible to accommodate 1/4 more energy in the same volume.
  • Improved operation life by 50% : Cycling tests performed show a performance of 3000 cycles of full charge-discharge cycles (100% depth of discharge) at 1C. This represents a 50% increase in the number of cycles compared to the previous generation.
    At a DoD of 80% at 1C, the number of cycles performed rises to 4500.

Below chart shows the estimated number of cycles for our new generation of Lithium LiFePO4 cells, according to the discharge power and DOD figures. The test conditions are those of a laboratory (constant temperature of 25°C, constant charge and discharge power).

Lithium Iron Phosphate Life Cycle
Life Cycle chart of new LiFePO4 cell generation

We can read from the chart the below figures :

  • 3 000 cycles at 100% DoD @ 1C
  • 4 500 cycles at 80% DoD @ 1C
  • 10 000 cycles at 60% DoD @ 1C
  • etc.

It should be noted that following the number of completed cycles, the cell still have a nominal capacity > 80% of the original capacity.

Our main product ranges: PowerBrick, PowerRack and PowerModule, will benefit in the coming months from this new generation of cells with an increase in capacity, a reduction in weight but also a significantly improved lifespan.

The E-mobility market today

Electro-mobility becomes more democratic

It is the ability or property for people or objects to move in a space, by a means of transport using partially or totally electrical energy.

Today, electromobility meets a major challenge in the fight against global warming. That of the replacement of polluting thermal engines by electric models more respectful of the environment.

According to figures released by the IEA (International Energy Agency), the number of electric cars in circulation around the world has sharply increased in 2016. With more than 750,000 units sold (40% more than the previous year), the market of green vehicles has exceeded the symbolic bar of 2 millions of units.


Some key figures:

  • China has become the main market for electrically powered cars. With more than 336,000 new registrations, it concentrates more than 40% of global sales in 2016. Moreover, there are 200 million electric two-wheelers and more than 300,000 electric busses.
  • In second place is Europe with more than 215,000 green cars in 2016.
  • In Norway, electric cars account for 1/3 of new car sales.
  • Next come the United Kingdom, France (where electromobility represents only 1.5% of the market share), Germany, Sweden and the Netherlands.
