Loading technology and Solar

LINK TO THE ITINERARY

It is 6:00 a.m. We load our bikes. None of the street children is to be seen at the moment, probably too early this morning for adventures in town. For the memory of our stay in the city Darkhan we shoot a few photos in front of the big Buddha's statue. Then we start the today journey in direction Ulan Bator. The traffic has violently increased. The Asian highway 3 is not any more the lonesome road like we remember it from some years ago. We must concentrate to hold the track. At some places there are little scarps of the street to the side stripe. So that we doubt our trailer could tip if the right tyre leaves the street. Suddenly we see a unusual silhouette coming towards us. While getting closer we recognise two cyclists. Steve and Marco come from Italian Switzerland. They transported their bikes by airplane to Ulan Bator and are on the move for three weeks in this country. We have a briefly exchange, take a photo of ourselves mutually to continue after a little while the trip in different directions.


Meanwhile our E bikes working their way up to 1,000 meter altitude. The engines support us furthermore without problems. After 30 km I change the accumulator one (out of three per person) and put it, as well as already during the last travel days, directly to the Goal Zero battery. Based on my long-standing experience with solar technology I have put together a loading system back in Germany during the preparation for this journey: two times 60-watt panels and two solar generator Goal Zero yeti 150, I call it “buffer battery” it is responsible to store the energy which is won by the solar panels and to transmit the energy in smoothed form to the accumulators. If I would connect the Bosch accumulators directly to the solar panels, I would bring the 12 volts net parts in danger because of the constantly changing loading tension, after some time they would become simply overloaded.

If a Bosch accumulator is empty I connect it to the yeti 150. The yeti 150 is getting loaded by the solar panels. The idea was that during the loading of a Bosch accumulator at the same time the buffer battery (yeti 150) is fed by solar. However, the solar energy gives not enough power to hold the Goal Zeros (yeti 150) in a consistently filled power situation. For that we would need a bigger solar surface with more watt. However, the Goal Zero is able to load the Bosch accumulator to three quarters fully, than it is at the end with its capacity even in spite of solar supply. We could also have taken two bigger, approx. 13 kilogramme Goal Zero to handle the problem of the quick unloading.Because we transport everything by ourselves without a supporting vehicle we had to make compromises.

These days it appears that we extend our range of action in the mountainous area by approx. 20 km with the help by the buffer batteries. We are able to ride our e-bikes about 30 km per accumulator with heavy load and many mountains. Having three Bosch accumulators per person, one reload at a street restaurant and the additional load by the buffer battery we own a range of action of approx. 140 kilometres. This current experience value results exclusively from the local geographic situation and the additional load of an accumulator in a socket. For us this range of action is astonishing and surpasses any expectations. We will see which experience the future time and distance will bring and how the reach of the accumulators thereby changes.
