from chemistry to pack
The UBTECH Robotics Walker S2 robot battery swap demonstrates a robot that can operate indefinitely. The robot has two battery packs, thus allowing one to be removed and placed in the charger before a fully charged pack is taken from the charge station and placed in the robot. Uses: Factory floor automation, assembly line co-worker, … Read more
In the first instance it is all about requirements. What are the hard points, the inviable parameters? My first thoughts are around these headings: This post has been built based on the support of and sponsorship from: Quarto Technical Services, Eatron Technologies and About:Energy Initial sizing is around Electrical and Thermal. The Battery Calculations Workbook has some great tools to … Read more
What are the Cold Temperature Charge / Discharge limitations and mechanisms? At cold temperatures lithium ion cells suffer from a significant decrease in available capacity. The DCIR of the cell increases significantly as the temperature decreases. Significantly reducing the available peak and continuous power.

What is different about the operation of a drone and hence what does this mean in terms of battery requirements? For a drone we are meaning an unmanned drone as used for photography or surveillance. The fundamental parameters are: This post has been built based on the support and sponsorship from: Eatron Technologies, About:Energy, AVANT Future Mobility, Quarto Technical … Read more
When thinking about sizing a battery pack it is worth stopping and considering the data required to size a pack. These are the requirements. If you don’t have these then the design is likely to change considerably, these changes will cost time and can ultimately end in a poorly optimised design. The usable energy for … Read more
