Hymer Cooperation

Bad Waldsee, Germany

BOS Lithium Extension Batteries are the main component of the new
innovative hybrid storage battery for Hymer caravans.

HYMER GmbH & Co. KG is one of the largest manufacturer of motorhomes and caravans in Europe. The HYMER-smart-battery-system will offer more freedom of energy and independence in travel. Thanks to the significant higher self-sufficiency and integrated battery heating, campers can stay many days longer at a beautiful place, even in winter. The system is installed as standard in selected models and can be retrofitted in all motorhomes and caravans.

In partnership with:

2.77 kWh total usable battery capacity

71% Lithium

29% Lead Acid

1.97 kWh lithium capacity (6x LE300)
0.8 kWh lead acid (95 Ah / 70% DOD)
Values are in standard configuration.
Other capacities are also availabe.

Making the world and people’s lives a bit better is what drives us and what we do every day with our projects. Get to know many more of our projects in countries all over the world with different climates, cultures and people.

Electrifying Mountain Huts

Norway is known for its natural wonders such as fjords, mountains and northern lights. If you go on a tour in the nature you often spend the night in one of the numerous huts and experience the beautiful nature far away from civilization. But especially for the hut owners this also means away from any electricity connection. After the Grimsdalshytta built a new winter drying room, the owner decided on a solar system that has to work in winter. Therefore, they decided to install our HS500 hybrid storage system. Due to the very short sun duration the solar panels were installed very steeply and with large surface and by a special cold insulation for the HS system, it resists also in the winter problem-free. Local electricians have been trained in the technology so that maintenance and repairs can be carried out quickly.
From now on the new drying room will be supplied with light in winter and guests can recharge their mobile phones and cameras to be prepared for the breath taking nature.

Sailboat Windzang

The passionate sailor Peter Reinmann extended his lead acid energy storage of his 9.30 meter long sailing catamaran with two BOS LiFePO4 Lithium modules. Peter is thus able to operate all the on-board electronics such as navigation, radio, light, refrigerator and gas heating. Because there was no room under the bench seat for a larger supply battery, a LE300 hybrid system was the perfect solution without loosing too much space. Now he is able to enjoy longer trips on the water without returning for recharge. A freedom that he no longer wants to miss.

Katate Health Center

The existing health station of Kanungu was in a very poor condition. Simple birth complications, fractures, and infectious diseases often led to death. A state-private initiative turned it into a fully functioning
hospital. Thanks to our energy storage systems, all necessary loads can be handled, especially for operations like autoclave, vacuum pumps, electrosurgical
cutters, anesthesia equipment, and surgical lights. For secure energy supply, BOS energy systems combine electricity
from solar energy, the main power grid, and a diesel generator. This project shows that even in remote areas a very
high medical level is possible.

Kenti Island

The remote island of Kenti is a hub of fisheries export. The only available power access on the island was from a diesel genset. Since diesel runs for four hours per day, cold storing was almost impossible. In 2017 after a World Bank investment, a solar-diesel mini grid was built. However, power capacity was soon not enough. So, BOS AG supplemented the lead-acid mini grid with BOS lithium storage systems into a hybrid solution. Today, with its extended capacity and a whole optimized system, the diesel generator is used only as a bad-weather backup and 340 households are supplied with electricity around the clock.
