“…They also give the cycling capacity loss of the cells based on the number of charge-discharge cycles at different temperatures. As a general trend, the data presented in [57,58] show that storing the battery at higher SoC or temperature increases the rate of capacity loss. Furthermore, a higher number of cycles increases the capacity loss, especially when the cells are cycled at higher temperatures.…”

“…First, during the morning hours when the heat gain from the ambient environment is comparatively low, a mild level of cooling is applied to maintain the battery in the range of 23 • C-25 • C. Second, cooling intensifies when the SoC drops below 70% (at approximately 8 a.m.). This is because the capacity loss in the battery cells is highest in the SoC range of 50-70%, according to the dataset implemented in the model [57,58]. Therefore, the cooling decisions are dominated by the tendency to discharge the battery below 50% SoC.…”

Ambient conditions can have a significant impact on the average and maximum temperature of the battery of electric and plug-in hybrid electric vehicles. Given the sensitivity of the ageing mechanisms of typical battery cells to temperature, a significant variability in battery lifetime has been reported with geographical location. In addition, high battery temperature and the associated cooling requirements can cause poor passenger thermal comfort, while extreme battery temperatures can negatively impact the power output of the battery, limiting the available electric traction torque. Avoiding such issues requires enabling battery cooling even when the vehicle is parked and not plugged in (key-off), but the associated extra energy requirements make applying key-off cooling a non-trivial decision. In this paper, a representative plug-in parallel hybrid electric vehicle model is used to simulate a typical 24-h duty cycle to quantify the impact of hot ambient conditions on three performance attributes of the vehicle: the battery lifetime, passenger thermal comfort and fuel economy. Key-off cooling is defined as an optimal control problem in view of the duty cycle of the vehicle. The problem is then solved using the dynamic programming method. Controlling key-off cooling through this method leads to significant improvements in the battery lifetime, while benefiting the fuel economy and thermal comfort attributes. To further improve the battery lifetime, partial charging of the battery is considered. An algorithm is developed that determines the optimum combination of key-off cooling and the level of battery charge. Simulation results confirm the benefits of the proposed method.

“…For example: The use of battery pack that are incorporated in EVs equipped with bi‐directional charging systems is proposed by Reference. Commercially available lithium‐ion batteries (C 6 /LiNiCoAlO 2 type) are used and a degradation model is developed and validated. This model is integrated into a smart grid management algorithm.…”

Smart grids are one of the major challenges of the energy sector for both the energy demand and energy supply in smart communities and cities. Grid connected energy storage systems are regarded as promising solutions for providing ancillary services to electricity networks and to play an important role in the development of smart grids. The aim of the present article is to analyze the role of storage systems in the development of smart grids. The article includes an analysis and a list of energy storage systems that are applied in smart grids. Various energy storage systems are examined raging from electrical, electrochemical, thermal, and mechanical systems. Two case studies are presented that show the role of energy storage in effective management of energy demand and supply.

The Impacts of High V2G Participation in a 100% Renewable Åland Energy System

2018

A 100% renewable energy (RE) scenario featuring high participation in vehicle-to-grid (V2G) services was developed for the Åland islands for 2030 using the EnergyPLAN modelling tool. Hourly data was analysed to determine the roles of various energy storage solutions, notably V2G connections that extended into electric boat batteries. Two weeks of interest (max/min RE) generation were studied in detail to determine the roles of energy storage solutions. Participation in V2G connections facilitated high shares of variable RE on a daily and weekly basis. In a Sustainable Mobility scenario, high participation in V2G (2750 MWh e ) resulted in less gas storage (1200 MWh th ), electrolyser capacity (6.1 MW e ), methanation capacity (3.9 MWh gas ), and offshore wind power capacity (55 MW e ) than other scenarios that featured lower V2G participation. Consequently, total annualised costs were lower (225 M€/a). The influence of V2G connections on seasonal storage is an interesting result for a relatively cold, northern geographic area. A key point is that stored electricity need not only be considered as storage for future use by the grid, but V2G batteries can provide a buffer between generation of intermittent RE and its end-use. Direct consumption of intermittent RE further reduces the need for storage and generation capacities.
