What an exiting adventure! After more than two years of hard work and a 3000 km race through the Australian outback, our Huawei Sonnenwagen made it across the finish line in Adelaide. The last months were full of new challenges, teamwork, emotions, surprises and sleep deprivation. Since time has gone by very quickly lately, it is time to recap our trip to Australia.   The weeks before the race  The first few members of the team arrived in Darwin at beginning of September, just a few ...
  Hallo liebe Fans, Freunde und Familie, endlich ist unser Huawei Sonnenwagen gestartet! In einer feierlichen Zeremonie haben sich alle Solarrennfahrzeuge im Regierungsviertel von Darwin gemäß ihrer Startposition aufgereiht. Nach unserer tollen Leistung gestern beim Qualifying traten wir auf Platz 5 an, was uns einen kleinen Startvorteil gegenüber den anderen Teams gewährte. Das gesamte Team war selbstverständlich zum Start versammelt, auch wenn auf manche noch A ...
Hallo liebe Fans, Freunde und Familie, was für eine Woche! Diese stand ganz im Zeichen des Scrutineerings und Qualifyings, also den Prüfungen, die unsere Zulassung und Startposition für das Rennen entscheiden. Wir haben so lange auf diesen Moment, unser großes Abenteuer in Australien, hingearbeitet, da machen wir selbstverständlich nicht auf der Zielgeraden schlapp. So wurde wie immer die ein oder andere Nachtschicht geschoben, letzte Details an unserem Huawei Sonnenwag ...
During our trip through the Australian outback, we don't want to leave anything to chance. For that reason, our solar car is equipped with a large number of sensors. We do not only measure things like the vehicle's velocity or the battery voltage, but also less obvious values such as the temperature of our solar cells.   All measurement values are wirelessly sent to one of our escort vehicles using a self-designed telemetry system. The transmitted sensor values are automatically preprocess ...
The special task of designing a chassis for a solar car  When it comes to building a solar car, of course, one important part is the design of the chassis. It does not only establish the contact between the road and the car itself but it is also essential for the efficiency of the whole car. With that in mind, we started our design process from scratch more than a year ago and this is how we came up with our final design.   The very special use-case of a 3.000 km race through the outb ...
The biggest amount of work when producing fibre reinforced parts is the mould manufacturing. There are many ways to design and manufacture moulds, which all differ in material, cost, time and the process eco-friendliness.   Material  The common way when producing moulds is the use of polyurethane raw blocks with a density between 450 and 700 kg/m³. The material’s disadvantages are the weight and the price. For our solar car, the mould dimension of the main body alone is 50 ...
What to take into account, when designing a battery pack for a solar car?  The battery pack is an important part of the electrical system of a solar car. It is used to store excess energy, generated by the solar cells or by recuperation, that is not immediately needed to power the motor. If the solar cell power is not sufficient to drive at desired speed, due to cloudy weather or a steep ascent of the road, this stored energy is used additionally.   Main Part of the Battery Pack: Batte ...
The main goal of an efficient solar car is to make the most of the energy that the sun provides for us. To maximise the irradiation input of our only power source, our solar panel will be made of solar cells with the highest possible efficiency to gain as much electricity as possible.     Making the most of what we got   Unlike a common battery, the behavior of solar cells under load cannot easily be described as the series connection of an ideal voltage source and a constant ...
