A key focal point of this review is exploring the benefits of integrating renewable energy sources and energy storage systems into networks with fast charging stations. By leveraging clean energy and implementing energy storage solutions, the environmental impact of EV charging can be minimized, concurrently enhancing sustainability.
Using energy storage with less capacity can save cost and weight. For the example considered, a BOL capacity of 90 kWh (80% reduction in respect to the previous example) is assumed. Given the recharge power of 540 kW, this corresponds in a charging C-rate of 6, too high for a ‘high energy’ optimized battery.
The profitability and functionality of energy storage decrease as cells degrade. The economic end of life is when the net profit of storage becomes negative. The economic end of life can be earlier than the physical end of life. The economic end of life decreases as the fixed O&M cost increases. Indices for time, typically a day.
Despite intensive research activities, mobile energy storage is still the limiting factor, curbing the success of hybrid and electric vehicles. Since the direct storage of electrical energy can be realized only by the capacitors and coils, indirect storage methods prevail.
In order to dimension any energy storage device accordingly, the predictability of the duty cycle is absolutely essential. Hence, one of the best predictable use-cases—public transport bus service—was chosen. To be more precise, the case of fully electrified buses with on-board energy storage (no hybrid- or trolley-variants) is considered.
