“…The principal function of this architecture is to transfer the Maximum Power from a PV panel and store and/or restitute the energy to the load. For that, an electronic management system was designed and implemented on a microcontroller to control all subsystems [9]. The DC power converter connected to the PV generator is associated with a Maximum Power Point Tracking (MPPT) optimizing the research of the Maximum Power delivered by the PV generator.…”

Abstract. An approach to the analysis and design of a bidirectional DC power converter for the cell voltage balancing control of a series connected lithium-ion battery string is presented in this paper. The proposed Cell Balancing Circuit (CBC) is designed to transfer the energy from the fully charged battery cell to the weakest one using a switch mode power converter operation. This operation maintains cell batteries at the same State-Of-Charge (SOC) and voltage range. Unlike previous battery balancing circuits, the balancing method uses only one magnetic component, resulting small size system. Simulation and experimental results show that the proposed cell balancing method can not only enhance the bidirectional battery equalization performance, but can also reduce the switching loss during the equalization period. Experiment results are provided to verify the operating principle of the proposed balancing method. Specific conditions of experiments are used to reproduce photovoltaic operations.

“…As a continuation, a prototype of the MPPT circuit board and battery management system board were presented and individually tested in Reynaud et al The battery management system (BMS) was designed to keep the cell operating safely and to reduce the impact on lifetime. The BMS limits the charging and discharging process by monitoring the voltage and comparing it with predefined thresholds, calculating the rate of discharging and charging, implementing specific charging or discharging method (ie, constant current or constant voltage), and determining battery state of health (SoH).…”

Due to the variable nature of the photovoltaic generation, energy storage is imperative, and the combination of both in one device is appealing for more efficient and easy-to-use devices.Among the myriads of proposed approaches, there are multiple challenges to overcome to make these solutions realistic alternatives to current systems. This paper classifies and identifies previous efforts to achieve integrated photovoltaic storage devices. Moreover, the gaps and future perspectives are analysed to give an overview of the field, paying attention to low-power devices (<10 W) as well as high-power devices (>10 W). We focus on devices that combine solar cells with supercapacitors or batteries, providing information about the structure, materials used, and performance. On the one hand, small power devices must concentrate on including power electronics to increase the efficiency of the system as well as ensuring a safe operation; likewise, more attention should be drawn to validate the feasibility of novel concepts by carrying out more realistic and standardised tests, including long-term testing. On the other hand, high-power devices must be researched thoroughly to evaluate the impact of high temperatures on energy storage and solar module ageing; furthermore, optimum system sizing is a relevant topic that deserves attention and its relation to modular solutions. This critical literature review serves as a guide to understand the characteristics of the approaches followed to integrate photovoltaic devices and storage in one device, shedding light on the improvements required to develop more robust products for a sustainable future. KEYWORDS battery, one device, PV-storage integration, solar-battery integration, solar energy, supercapacitor 1 INTRODUCTION Solar photovoltaic (PV) energy generation is highly dependent on weather conditions, making solar power intermittent and many times unreliable. Moreover, energy demand is widespread during the day, and solar energy is available for few hours, provoking a mismatch between demand and supply. These two issues are the driving force behind the use of energy storage (ES) devices, which help decrease the fluctuations from the generation side but also provide the possibility of performing ancillary services. Consequently, it is fundamental to find the most appropriate energy storage device for particular applications and operational conditions.According to the characteristics of ES devices, the criterion that defines when the energy is stored and utilised may vary, even for the same component. Some ES devices can supply power during extended periods (hours, days), while others are more suitable for shorter periods of operation (seconds, minutes). For instance, rapid changes in PV power due to rapidly changing illumination conditions can be smoothed using supercapacitors (SCs); they deliver power when solar supply is scarce, so the load is still satisfied. For devices with lower self-discharging values like electrochemical cells (batteries), the electrical energy produced by...

“…Similarly, in [19], an electronic control unit includes a converter in charge of performing maximum power-point tracking (MPPT), a battery charge/discharge controller, and a battery management system. Particular interest is given to the battery management [20], where battery operation conditions are monitored closely including state of health, temperature, and state of charge levels. As a continuation, a boost converter is proposed to take care of the PV optimal operation, wherein three switches control the power flow [21].…”

Given the complementary nature of photovoltaic (PV) generation and energy storage, the combination of a solar panel and a battery pack in one single device is proposed. To realize this concept, the PV Battery Integrated Module (PBIM), it is fundamental to analyze the system architecture and energy management. This paper focuses on selecting a suitable architecture among the different options, while also indicating the control strategy that the converters must follow to ensure appropriate performance. Also, several modes of operation for the complete system are introduced to implement energy management. For the selected DC architecture, two case studies, viz. off-grid and peak-shaving for a grid-tied system, were employed to characterize the response of the model demonstrating its utility to perform maximum power-point tracking, excess solar power curtailment, and battery charging and discharging. The proposed control and system architecture prove to be feasible for a PV Battery Integrated device such as PBIM.
