Charging solutions for electric bus fleets

Operate your electric buses reliably and at the lowest cost

We offer smart charging solutions and give you advice, regardless of the manufacturer.

Spurred on by discussions about pollution in congested metropolitan regions and the transformation in mobility, electric mobility is continuing to gain momentum. Attractive transportation possibilities also contribute to the continually growing percentage of electric buses used in local public transport. The switch to electric buses entails more than just a change in the type of drive. New technical and economic conditions of your electric buses also require an intelligent charging solution.

Advantages of electric buses at a glance

Icon - sustainability

Fewer Emissions

Electric buses are free of emissions (locally) and produce less noise when driving.

Icon - efficiency

High degree of efficiency

The efficiency of an electric drive and the possibility of recuperation provide for a high degree of efficiency.

Icon - saving costs

Reduced total costs

Today's electric buses already demonstrate lower operating and maintenance costs (TCO) than diesel buses.

Icon - happiness

Great ride comfort

Electric buses accelerate smoothly and almost silently. This significantly increases comfort during the ride.

Charging types

Essentially, charging types are split into two groups: Alternating current (AC) charging and direct current (DC) charging

Explanation: Batteries for electric vehicles can only be charged with direct current. Our power grids supply direct current or alternating current depending on the location and voltage. To convert the AC into direct current, rectifiers are needed to charge the battery if an alternating current connection is used.

In the case of plugs for DC charging, these rectifiers are already in the charging station and not installed in the vehicle, and therefore enable greater charging power than with AC charging. In AC-charged vehicles, less powerful rectifiers are fitted in the vehicle for space reasons, which limits the amount of charging power.

Plugs for AC Charging

  • Type 1 plug: for Asian models; charging power up to 7.4 kW
  • Type 2 plug: for European models; charging power up to 22 kW or 43 kW
  • CHAdeMO plug: Quick-charge system from Japan; up to 100 kW
  • CCS plug: Quick-charge function with AC and DC; charging power up to 170 kW (350 KW)

 

Plugs for DC charging

Pantograph: On-route charging up to 450 kW

Charging and energy management from The Mobility House

charges your electric buses reliably and reduces investment and operating costs

How you benefit

Reduce investment costs

Control the charging processes of your electric buses intelligently. This means you will need fewer charging stations in total.

Minimize grid connection costs

When you control the charging of your bus fleet, a smaller grid connection is sufficient.

Lower grid usage charges

You can save on grid usage charges every month by reducing load peaks.

Save on energy costs

Charge during low-price phases and benefit consistently – this lowers your monthly electricity costs.

Our services for efficient running of electric bus fleets

Our goal is to provide you with a sustainable, cost-optimised charging solution for your buses. That is why we focus on a comprehensive approach for your charging infrastructure, from conception to operation.

1. Designing the e-bus fleet

To optimise the running of your electric bus fleet, your charging infrastructure should have a smart, customised design to meet your needs. We will create a innovative energy and infrastructure concept for you in five steps.

  • Evaluation of route data
  • Evaluation of the grid connection and energy landscape
  • Optimisation of charging processes with the help of our analysis software
  • Feasibility study of various scenarios
  • Creation of a customer-specific energy and infrastructure concept

2. Implementation

You can draw on our many years of experience with charging infrastructure projects of all sizes when implementing your concept. We’ll be happy to support you with the following based on your needs:

  • Design and planning of site-specific charging solutions
  • Determining tendering requirements
  • Procuring the relevant components, e.g. charging stations
  • Installation by our qualified specialist partners

3. Operating the e-bus fleet

We ensure that your electric buses are cost-optimised and charged depending on the timetables, and therefore guarantee that your e-bus fleet runs to schedule every time. We focus on the following:

  • Meeting the charging requirements
  • Load balancing for cost-optimised operation
  • Reduction of ongoing costs for grid usage and electricity consumption
  • Monitoring and control of charging processes in the customer portal
  • Interfaces to control centres and depot management systems

„The Mobility House analysis makes all the difference when we’re looking to reduce the ecological footprint of our fleet. At the same time, we can ensure that our operating costs stay low.–
Managing director

A bus company which operates a bus fleet for local transit in its region, among other things, wants to serve as a pioneer in the public transport sector by switching its fleet from diesel buses to electric buses. In this specific case, it is particularly important that routes around a national park are covered by zero emissions buses. We delivered a concept that will charge the fleet reliably and cost-efficiently. Timetables with the related distances form the basis for developing our solution. Using our analysis software and smart load balancing, we develop a charging infrastructure solution via which we can reduce grid expansion. By reducing the load from 2.3 MW to 0.5 MW, the company saves investment costs of € 320,000 as well as € 140,000 annually on running costs. We also look at whether integration of a solar system with stationary storage is an option, and whether it is cost-effective for operation of the fleet.
