The GWL VZV Forklift Battery Project
An innovative replacement solution forthe traction battery for the fork-lift trucksand warehouse transportation vehicles. The original lead-acid battery is replaced by high performance lithium iron-based battery that matches the dimensions, keeps the same weight but brings much mor
Avoiding petty risks with home storage
Perhaps a small neglection of the maintenance of an airplane can cause the whole plane to crash. Also, a small negligence can cause somerisky situations concerning the energy storage solution.
See two examples from the photos.

Using the proper terminals to connect the cells
When charged and discharged, expanding and stretching a little. The cells also change their shape due to the temperature expansion of the materials and the changes of the atmospheric pressure.
All of these factors cause that the cells are more or less b

The copper terminal oxidated – Why?
Some users and customers ask, why - when receiving the new cells – do the copper terminals have signs of severe oxidation.
Copper as a metal is prone to oxidation and reaction with other materials.The oxidation of the terminal is a matter of days. Also the black rubber cover on the top of the
The cell terminals must be perfectly clean!

QUOTE:
Use only the original copper terminals #1). There are many reasons why you should not use any other accessories #2) to connect the cells. Check our knowledge-base for details #3), if you are interested in.It is very important to clean all connectors and terminals perfectly with sandpaper just before assembly. #4). Even small resistance between the cells would dis-balance the battery.

BMS123 or GWL CPM? - Deeply discharged cells
As our customers are well aware, some type of protection module is necessary to use with every lithium battery for prevention of a deep discharge or overcharge.
I will use the example of our customer from Holland to describe how a significantly cheaper GWL CPM protection can often be the better choice th
The energy generation by Stirling Motor
The GWL/Power team is also experimenting withthe energy generation from heat by a Stirling motor. The Stirling motor is installed on top of the OKOFEN Power-generating pellet boiler.
The demonstration shows the real power from the1000W Stirling Motor generation. The output power rated at the AC part of the
Is the Bestie the Best or the Beast?
“The Bestie” is the“Beast” and it is the “Best of the Beasts”. Actually this is the very first photo of the GWL/Modular complete solution, to be installed in the Czech Sustainable Houses project, after it has arrived to GWL/Warehouse in mid summer 2020.

Simple testing is the best testing
Making a simple testing of the new BMS for a customer application. As we say, we sometimes need to test whether the wheel is really round. Or what you test is what you do not need to believe.
