We needed a prototype of an electric motor to see if it fits into our customer's electric vehicle. We could easily prepare the model in our workshop, using Ultimaker 3D printer. The printing took 20 hours. The prototype was made of PLA plastic. It was printed in two parts, because of the complex structure of the item.
Ultimaker 3D printer suits very fine for preparing prototypes. Using prototypes saves money, because you can make all the needed improvements into the protoype.
Spring is now here in Finland and the roads are ready for bicycling. Our customer needed electric bicycles so we assembled accus, electric motor and motor controller into bicycles. The accus are lithium-ion accus.
You can easily adjust the effectiveness of your exercise by using electric bicycle. You don't need to sweat, if you use bicycle on work trip. If you want to exercise harder, don't launch the electric motor.
We designed and built a heated bed into Ultimaker 3D printer. The bed is made of aluminium and it uses own and more effective power source. The heated bed expands the printing possibilities. It makes possible to make demanding ABS plastic items. During the printing process, the item won't curl up because of the heated bed.
The temperature of the bed can be adjusted in controller panel.
We've been developing an new BMS system for our client. Recently we got first prototype PCB's and made first test solderings of the new BMS system. The system consists of 4-12 cells per card, max. 16 cards per bus. It also contains an isolated CAN-bus and pins for external power supply. Circuit board is designed by Eero Vuorinen.
Stay tuned for more information!
Recently we did some Elcat - electric van battery maintenance work. We balanced whole battery pack and made some individual capacity testings on selected cells. We used 3 units of 300A 0-5V power supplies to charge those 300A batteries. In the near future we can load-test single cells up to 600A DC / 4 kW.
PalonenLabs has designed and prepared an adapter between Volgswagen Polo gearbox and Kostov electric motor. Adapter uses the original gearbox disk that contains suitable bore. There are two M6 bolt sockets outside of the adapter, which will give rotation speed signal into Solition JR motor controller.
PalonenLABS has developed an system that controls two or more Eltek Valere Powerchargers on the same CAN bus. Charger outputs are connected in parallel and they are also connected to the same CAN bus. It is possible to reach 6 kW power-levels with two chargers and even more as needed - the system can support up to 16 chargers.
