Parallel Battery Management System for Electric Vehicles

Abstract

Battery bank comprises of ‘N’ No. of. Battery pack where the required cells are connected in parallel and each pack will be made to connect both in series and parallel combination to attain a required voltage. Multi Secondary Coaxial Winding Transformer is used to maintain the battery in balanced condition. During charging and discharging of battery, each battery pack is connected to the secondary winding of transformer including Electronic Switches, Temperature Sensor, Voltage & Current Sensor. The voltage, current and temperature sensor is used to measure the parameters of each pack, from which the state of the health, state of the charge and temperature of the battery can be calculated. The voltage induced in the primary side is based on the switching frequency & duty cycle of the MOSFET. To compensate the required voltage needed by the load, a boost converter is connected to the system on the primary side of the system where the transformer will be coupled. The output is connected to the inverter that produces power to drive a BLDC motor.

Dual Battery Controller for Solar Based Electric Vehicle

“…• Lower operating costs: Solar energy is free and abundant, and by using it to charge the batteries of the electric vehicle, the operating costs of the vehicle can be significantly reducedAbdullah et al (2017),Pratap & Srinivasan (2020). • Environmental benefits: Solar energy is a clean and renewable energy source, and by using it to power an electric vehicle, the vehicle can significantly reduce greenhouse gas emissions and other pollutants associated with traditional fossil fuel vehiclesAbdullah et al (2017),Panneerselvam & Muruganantham (2019).…”

Study on the Effect of Hydraulic Energy Storage on the Performance of Electro-Mechanical-Hydraulic Power-Coupled Electric Vehicles

“…At the same time, the electric motor starts to work, converting mechanical energy into electrical energy, which is stored in the battery pack through the power converter. The new electromechanical-hydraulic power transmission system proposed in this paper effectively combines the characteristics of zero-emission and no pollution in pure electric vehicles [22] with the high energy recovery rate and high power density of the hydraulic systems in hydraulic hybrid vehicles [23], and as a result, it better meets the needs of the economy, reliability, and safety of vehicles [24].…”
