Efficiency

The efficiency of the system as a whole plays a very important role in the case of powered wheelchairs. The more efficient the design of the vehicle, the more energy can be converted directly into motion. The goal is to be able to utilise as much of the energy stored in the battery pack for drive purposes. Every form of energy loss is a loss of mobility.

Alber has extensive know-how in the field of drives and has applied its many years of experience to develop and improve its drives even further.
The drive fitted to Adventure currently boasts efficiency of approximately 80%. Consequently, a very large share of the battery pack\'s energy reserve is available for use by the driver. This means the battery packs used in the ADVENTURE are considerably smaller than those conventionally used until now in electric wheelchairs, a point which also means a saving in weight.
When driving along without consuming much energy—when travelling down hill, for instance—the drives actually act as dynamos, generating energy that is fed back to the batteries, thus increasing the range of the ADVENTURE. If you go for a battery capacity of 44 Ah, this regenerative function will actually give you a range of 45 km.
