LOWAGO: the portal for charging tariff comparison

Triplesense Reply develops comparison portal for public charging electricity tariffs for MAINGAU Energie GmbH.

Contribution to the popularization of electric mobility

For MAINGAU Energie, Triplesense Reply has created Germany’s first online comparison portal for public electric vehicle charging tariffs. The platform provides a price calculation based on your own vehicle and your personal driving style. The slogan ”always on the move at a reasonable price” makes clear the aim of MAINGAU Energie to promote sustainable everyday mobility with LOWAGO as a key focal point.


The heart of the portal is the charging tariff comparison

The objective of the LOWAGO portal is to create greater transparency with regard to the cost of charging electric vehicles and hence to promote the acceptance of e-mobility as a key pillar of the automotive revolution. The integrated tariff calculator provides a clear comparison of the numerous tariffs of various providers, enabling consumers to choose the ideal tariff to suit their requirements at public charging stations. The calculation takes into account the vehicle type as well as the average distances driven. The search function can also be further refined by means of individual filters.

Pivotal function in the extended e-mobility ecosystem

The LOWAGO platform networks a variety of market participants on a B2B basis and at the same time forges a link with the consumer. For this reason in particular, the user-friendliness aspect and the creation of a convincing customer experience were of key importance while developing the platform. The user experience is enriched with an offering of information that offers genuine added value. In addition to the tariff calculator, it also includes a list of providers, a search function for charging stations and a blog section.

The portal, which was created by Triplesense Reply for MAINGAU Energie, is thus making a crucial contribution to the popularisation of electromobility as a key element on the journey to a climate-neutral economy.
