This month we focus on electronic development. kiwee electronics will be updated to version 2.0 to improve thermal dissipation and enhance reliability and efficiency. left image : focus on power MOSFET, right image: thermal photo to detect hot point

Ce mois si l’accent a été mis sur l’optimisation de l’électronique du Kiwee. Nous allons passer à une version 2.0 de notre carte électronique pour améliorer les performances. Image de gauche: les MOSFET de puissance, image de droite: détection des points chaud de la carte

Coding

Coding kiwee is a tricky part. There is a cinematic for reel in/reel out phase , a complex battery management and an electric generation function to implement. We have to take into account battery level, charging current, battery state of charge, instantaneous production and consumption, plus a maximum power point tracking to get maximum efficiency. discover our electric generation test bench on video below.

La programmation de Kiwee est complexe. Il y a une cinématique de rembobinage/débobinage, une gestion de la batterie ainsi qu’un fonction complexe de génération électrique a implémenter. Nous prenons en compte le niveau batterie, le courant de charge, la production instantanée ainsi que la consommation. Et par dessus cet ensemble, on rajoute une fonction de recherche de puissance maximale pour être sur d’obtenir les meilleurs performances de notre produit. Découvrez une vidéo de notre banc de test.

So they are going for a two stage crowdfunding? First Kickstarter then equity crowdfunding?

The specs on their presentation paper is interesting. 1 kW fully autonomous operation makes this a very serious proposition.

Very curious to see where this goes.

Yes another crowd funding but totally different. First one was pre sale, this on is equity.
Ending in 2 weeks.
Our R&D program include a 1 kW fully autonomous product, program start : end 2020
Price target : below 5000 euros
Targeted market : remote telecom / water treatment / remote community for coastal and island

It is interesting to see how Kitewinder diversifies its production, adding a wind turbine. Numerous photos and a description are available on the link below:

This wind turbine is dedicated to Travel Vans. It can be mounted on a standard roof rack with M6 fixing nuts.

€200 between manual and auto rising. Hmm. I am in no doubt I would rather save €200 and mount it manually…
