  • Smart Battery Protection and Efficient Charging for Electric Vehicles

    In the new era of technology, Electric Vehicles (EVs) are playing an important role in sustainable transportation. However, there are some challenges in the adoption. These technologies face the problem of efficiency and safety. The proposed system gives a solution. By implementing a liquid cooling-based temperature management system, the battery system can operate within a safe operating temperature range. The autonomous charging systems use a dynamo motor to convert the vehicle's kinetic energy into electricity. A microcontroller-based system is implemented to monitor main parameters of the battery, such as cell and pack voltage, current, and temperature. A program is developed to maintain the temperature of the battery and switch between the primary and secondary batteries. For maintaining the temperature of copper tubing, liquid coolant, and a temperature sensor are used to prevent overheating, reduce the risk of hazards, and extend battery life. There are two batteries (primary & secondary) used to provide power. According to the SOC level, the charged battery is connected to the system, and the depleted battery is connected to the charger. Using autonomous charging, a dynamo motor converts a vehicle's kinetic energy to electrical energy, and it is used to charge the battery. The emergency grid charging option is included for situations when both batteries are depleted. By using a dual approach, the proposed scheme enhances safety and improves efficiency.

    In the new age of technology, we face different problems such as an increase in global warming and pollution, depletion of conventional energy resources, and carbon footprint. This leads to the use of electric vehicles. Choosing an energy storage system for these new technologies is an important task. So battery technology can be a good solution to the question. Hence, the Battery technology plays an important role in energy storage in these areas. It satisfies the purpose of being portable with a small size and can be placed anywhere. The performance of the battery depends on various factors like chemistry, temperature variation tolerance, load profile, and charging-discharging algorithm. For monitoring and controlling the Battery performance, a battery management system is established. BMS requires estimation of different parameters for the choice, monitoring, and controlling of the battery for better performance and efficiency when used for an Electric Vehicle. The paper covers topics related to battery parameter importance, estimations, and battery management systems for efficient operation. Common observations are like battery SOC estimation, SOH estimation, and SOT estimation for an efficient BMS.
  • A Transformer Less Inverter Topology for Renewable Energy Application with Smart Protection Unit

    The global transition towards sustainable energy sources like solar photovoltaic (PV) and wind power relies critically on efficient and reliable power conversion. At the heart of grid-connected renewable energy systems lies the inverter. It does the essential job of converting the direct current (DC) electricity generated by sources like solar panels or wind turbines into the alternating current (AC) electricity. Which is required by the grid and most appliances. Traditionally, this conversion incorporated a low-frequency isolation transformer. This provided crucial galvanic separation between the DC source and the AC grid for safety and voltage matching. However, the quest for higher efficiency, reduced cost, smaller size, and lighter weight has driven the rapid evolution and widespread adoption of transformer less inverter technology, particularly dominating the residential and commercial solar PV market. This paper presents a transformer less inverter topology for PV systems. The proposed system is built in two stages. First stage stands for PWM controlled boost converter while the second stage is configured with SPWM controlled H- bridge inverter followed by smart protection unit. The hardware experimental results on $400 \mathrm{~W}, 230 \mathrm{~V}$ SPWM controlled inverter model are presented which indicates good voltage regulation across load variations. The harmonic analysis indicates 2.5% THD for the lamp load.

    This research paper proposes STATCOM based reactive power compensation on grid connected solar system and a comparative analysis of STATCOM and capacitor bank. STATCOM is utilised to mitigate reactive power in power system. For optimal power extraction from a solar PV panels, The solar photovoltaic panel system is connected to the grid through DC-DC step-up converter and grid tied PWM inverter. ANN based maximum power point tracking method is used to extract the maximum power from a grid-connected solar system by controlling the duty cycle of the DC-DC step-up converter. An ANN block is trained using a variety of irradiance and temperature data. The Pulse width modulation(PWM) method based three phase inverter is designed using a dq0 transformation-based control technique. This suggested system has been tested under various load conditions. The STATCOM based system were simulated in detail, and comparisons were made.
