The new economics of energy storage | McKinsey

Energy storage absorbs and then releases power so it can be generated at one time and used at another. Major forms of energy storage include lithium-ion, lead-acid, and molten-salt batteries, as well as flow cells. There are four major benefits to energy storage. First, it can be used to smooth the flow of power, which can increase or decrease

6 FAQs about [How to deal with battery loss in new energy buses]

How to reduce the energy consumption of buses?

A method to reduce the energy consumption of buses is the implementation of eco-driving courses for professional drivers. However, the courses lose their effectiveness after approximately six months, as drivers return to their previous habits .

How good are bus battery systems?

The bus battery systems remained in good condition, with a maximum cell deviation of 3%, likely due to the vehicles’ newness. However, the continued monitoring of these systems will be essential, especially as the buses age and accumulate more kilometers, to ensure sustained energy efficiency.

How much energy does a bus use?

This enables the optimization of route planning, the strategic selection of stops, and the efficient scheduling of charging times, along with ensuring the proper scaling of the bus battery system. This study found that energy consumption peaked at 116.73 kWh/100 km in the lowest temperature range of −5 °C to 0 °C.

Why do Bus battery voltages vary in the tested buses?

Overall, the cell voltages in the tested buses showed small deviations. Of course, this could be due to the fact that a new bus battery system was analyzed in both cases. To monitor the changes, it will be worthwhile to repeat this study in a later stage, when the buses have driven more kilometers in 1 or 2 years. Figure 16.

Do buses have a battery problem?

Considering that buses are equipped with significantly more batteries than typical electric vehicles, detecting and localizing faults at the cell level is crucial to avoid the substantial costs and environmental impact associated with replacing large battery systems.
