This paper proposes a novel pack-to-multicell topology to equalize the voltage distribution of a series lithium battery pack. Switched-capacitor converters are implemented in a series-parallel configuration to simultaneously allow energy transfer from the entire pack to every cell. Those switched capacitors act as intermediary energy storage on equalization paths between each cell. The series-parallel term refers to two equalization phases of the switched-capacitor. At the series-connected phase, each capacitor is connected to its corresponding cell, so the cell’s voltage and capacitor’s voltage would be equalized. Subsequently, in the parallel-connected phase, all capacitors are connected so that they are set to the desired voltage value regulated by a DC/DC converter. The experimental setup of the proposed system has been tested on four series-connected 3000 mAh lithium cells, which have a large spread of initial voltages (2.69-3.92 volt). The experimental results show convergence of the cell’s voltages without over-equalization and a charge transfer efficiency of about 87%.

The specific capacitance and charge transfer properties of electrochemically exfoliated graphene (EG) are studied using various alkaline electrolytes. Scanning Electron Microscopy (SEM) and Raman spectroscopy results confirm the successful exfoliation of graphite into EG using electrochemical treatment. At similar concentrations, the prepared EG electrodes were then evaluated using different alkaline electrolytes, including LiOH, NaOH, and KOH. Cyclic voltammetry (CV) characterization result demonstrates that 1M KOH exhibits the highest specific capacitance $(116.04 mathrm{Fg}^{-1})$, followed by 1M LiOH $(67.29 mathrm{Fg}^{-1})$ and 1M NaOH $(88.26 mathrm{Fg}^{-1})$. Electrochemical impedance spectroscopy (EIS) result indicates that the sample tested using 1M KOH exhibits the fastest charge transfer and easiest ions penetration into graphene interlayers compared to 1M LiOH and 1M NaOH. These results indicate that the KOH electrolyte is promising for realizing a high energy and power density of EG-based supercapacitor electrodes.

Electric motorcycle users are required to be able to streamline the use of electrical energy. The application of speed limiter on vehicles is known to streamline the use of energy. Speed is limited to 40 km/h when the battery is below 20% so that this system can be applied and accepted in the community based on initial survey data. Therefore, a system is made to limit the speed of an electric motorcycle based on the battery level. The controlled variable is the BLDC motor speed with a control method using Fuzzy-PID with input in the form of error and delta error between reference speed and actual speed. The hardware used is Raspberry Pi 4 model B as a controller, FTDI, Logic Level Converter, MCP3008, and HC-06. The Fuzzy-PID output determines the PWM value to control the BLDC motor speed. The results show that the system can increase the efficiency of energy consumption on electric motorcycles by up to 57.3%. The average time required for the system to reach settling time at a speed of 40 km/h from several states is 7.363 seconds.

The battery utilization in electric vehicles needs to be operated at its operating temperature range of $20-45^{circ}mathrm{C}$ to hinder several issues, including a reduction of life capacity and thermal runaway. A battery thermal management system (BTMS) is based on a phase change material (PCM) and the heat pipe is harnessed to maintain the battery temperature. In this research, the BTMS by harnessing animal fat as the PCM and a heat pipe was investigated through experimental methods. Characterization material with the T-history method and thermal performance testing with three different loads of 0,5 C, 1C, and 2 C were conducted. The Findings showed that the proposed module batteries could be applied as the BTMS in electric vehicles due to their thermal properties, which had a melting temperature of 37,18°C and latent heat of 72,71°C. The proposed BTMS could reduce the temperature by 14, 7°C at the highest load of 2 C discharge rate from three discharge loads. Moreover, the temperature differences among batteries can be retained below 5°C. In conclusion, the proposed BTMS in this research has shown the ability to harness natural resources to reduce the battery temperature in electric vehicles. Thus, this can be a promising BTMS in the future.

The process of conversion of gasoline motorcycles to electric would be a solution to reducing fuel imports and greenhouse gas (GHG) emissions. P3tek KEBTKE has converted gasoline motorcycles to electric ones and tested the performance of the converted motorcycle. The gasoline motorcycle that has been converted to electric is NFIIBID M/T produced in 2010. The main process of conversion was replacing the combustion engine with an electric motor type BDLC Mid Drive 2 Kw/72V electric motor; battery capacity 72 V/20 Ah and electric motor controller 100 A/72 V. The method of performance test has tested initial gasoline motor and converted electric motor, which has used a dyno test to calculate power, torque, and emission parameters. The road test of the converted motorcycle on a flat contour to determine the energy consumption. The results test is gasoline motor decreased performance up to 35% before converted to electric and performance has increased 20 % after converted. Furthermore, the cost of an electric energy source for a converted motor is 9 times lower than using gasoline. This pilot has obtained SUT and SRUT certifications from the Ministry of Transportation, allowing government policies to be implemented.

The high rate of traffic accidents in Indonesia in 2020 was reported by Media Indonesia on September 30, 2020, which stated that traffic accidents (Lakalantas) increased by 1.28 percent in the 39th week compared to the previous week, with one of the factors contributing to traffic accidents being blind spots on vehicles, particularly container trucks passing through the port hinterland area. One of them is in Jakarta's northwestern outskirts. As a result, an application that has the potential to minimize the rate of accidents is required. These accidents frequently occur as a result of the driver's inability to detect and know the existence of other vehicles in the vehicle's blind areas. The ADDIE approach was used to conduct the study. This application will provide a warning sign of a vehicle passing on the vehicle's blind spot, also known as a blind spot, which comes from sensors installed on the vehicle's blind spot. It will also provide additional features such as blind spot understanding, blind spot simulators, blind spot detectors, equipment driving, driving procedures, and ethics. Regarding driving regulations, this feature will educate Indonesians, particularly the millennial age, on how to be more self-conscious and aware of the dangers of blind spots while driving, potentially lowering the likelihood of road accidents and assisting in the realization of several crucial aspects. Quality education is one of the Sustainable Development Goals (SDGs).

Electric motorcycles have a very simple machine construction consisting of a battery, controller and drive motor. The placement of these components affects the center of mass, where all the weight of the motor is centered in one meeting point or motor weight point. The problem of determining the position of the center of mass when converting a fuel motor to an electric motor is one of the things that must be resolved. To solve these problems, a center of a mass measurement system is made using the multipoint weighing method with four load cell sensors, the center of mass of an object can be determined by placing the measuring platform under the object to be measured and the position of the center of mass is obtained from the difference in mass measurements at the four load cell points. Sensor reading data is sent to Raspberry Pi from Arduino nano using serial communication and measurement results are displayed using Node-Red as a user interface. The Mass Center Measurement System was successfully implemented with the multipoint weighing method. The best position for mass measurement by varying the nominal load at the same interval is in the center of the platform with a percentage error rate of 0.00% and a repeatability value of 0.002. The results of testing the center of mass with validated objects obtained the percentage level of error of the measuring instrument below the permissible error limit of 10% and the percentage of success of measuring the center of mass of 95.39%. The measurement results of the motor center of mass before and after conversion obtained the deviation value of the center of mass based on the x coordinate of 2.24 cm, based on the y coordinate of 2.34 cm, and the height of the center of mass has a deviation of 1.53 cm. The position of the motor center of mass after conversion is still within the ideal area.
{"title":"Design of Multipoint Weighing in Three-Dimensional Object Center of Mass Measurement System Based on Raspberry Pi","authors":"Nuryanti, Afaf Fadhil Rifa’i, Mochamad Rivaldo","doi":"10.1109/ICEVT55516.2022.9924788","DOIUrl":"https://doi.org/10.1109/ICEVT55516.2022.9924788","url":null,"abstract":"Electric motorcycles have a very simple machine construction consisting of a battery, controller and drive motor. The placement of these components affects the center of mass, where all the weight of the motor is centered in one meeting point or motor weight point. The problem of determining the position of the center of mass when converting a fuel motor to an electric motor is one of the things that must be resolved. To solve these problems, a center of a mass measurement system is made using the multipoint weighing method with four load cell sensors, the center of mass of an object can be determined by placing the measuring platform under the object to be measured and the position of the center of mass is obtained from the difference in mass measurements at the four load cell points. Sensor reading data is sent to Raspberry Pi from Arduino nano using serial communication and measurement results are displayed using Node-Red as a user interface. The Mass Center Measurement System was successfully implemented with the multipoint weighing method. The best position for mass measurement by varying the nominal load at the same interval is in the center of the platform with a percentage error rate of 0.00% and a repeatability value of 0.002. The results of testing the center of mass with validated objects obtained the percentage level of error of the measuring instrument below the permissible error limit of 10% and the percentage of success of measuring the center of mass of 95.39%. The measurement results of the motor center of mass before and after conversion obtained the deviation value of the center of mass based on the x coordinate of 2.24 cm, based on the y coordinate of 2.34 cm, and the height of the center of mass has a deviation of 1.53 cm. The position of the motor center of mass after conversion is still within the ideal area.","PeriodicalId":115017,"journal":{"name":"2022 7th International Conference on Electric Vehicular Technology (ICEVT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130453096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
