7 challenges in charge management – and how to solve them

Many depots are not equipped for the high charging power required, as available grid capacity is limited. Without a charge management system, there is a risk of overload: charging processes are completed as quickly as possible and therefore start at maximum power. When several vehicles are charged simultaneously, this can create load peaks that overload the grid and result in buses not being fully charged.

MOBILEcharge dynamically controls all charging points based on demand, reducing charging power and distributing
energy across the available time window. This ensures that grid capacity is used efficiently without being exceeded.

Distributing the energy supply across the entire period available for charging has an additional benefit. As peak power demand is a key factor in determining electricity costs, reducing these peaks – known as peak shaving – can lead to significant savings. Energy consumption is managed more efficiently, lowering overall costs.

Without centralized charge management, there is a risk that vehicles are not charged in time – something that can easily go unnoticed. As a result, buses may not reach the required state of charge for their blocks and, in the worst case, may break down in service.

MOBILEcharge takes blocks, departure times and charging requirements into account, coordinating charging processes accordingly. It monitors charge levels, calculates required charging times and initiates processes as needed. Vehicles are ready when required, enabling reliable fleet operations.

Without automation, many tasks – from charge planning and fault resolution to vehicle dispatch – must be handled
manually. As fleets grow, this becomes increasingly time-consuming, error-prone and costly.

MOBILEcharge automates charge planning and prioritizes charging processes based on departure times, energy requirements and remaining range. In the event of issues, depot staff receive clear guidance, while intuitive dashboards provide full visibility of energy consumption, charging station utilization and system status. This significantly reduces workload, streamlines processes and allows staff to focus on core operations.

Frequent high-power charging can accelerate battery degradation over time, reducing range and limiting operational flexibility.

MOBILEcharge addresses this through battery-optimised charging. By supplying energy at lower power over longer periods, the system reduces thermal stress, protects battery health and helps maintain long-term performance.

Conclusion: E-mobility in public transport can only be managed effectively if intelligent charge management is in place. MOBILEcharge reduces costs, increases availability, eases the workload on staff and makes electric bus fleets efficient and reliable – both economically and operationally.
