Design of a Modular Battery Management System for Electric Motorcycle

Abstract

This paper proposes a modular battery management system for an electric motorcycle. The system not only can accurately measure battery voltage, charging current, discharging current, and temperature but also can transmit the data to the mixed-signal processor for battery module monitoring. Moreover, the system can control the battery balancing circuit and battery protection switch to protect the battery module charging and discharging process safety. The modular battery management system is mainly composed of a mixed-signal processor, voltage measurement, current measurement, temperature measurement, battery balancing, and protection switch module. The testing results show that the errors between the voltage value measured by the voltage measurement module and the actual value are less than 0.5%, about 1% under the conditions of different charging and discharging currents of 9 A and 18 A for the current measuring module, less than 1% for the temperature measurement module; and the battery balancing in the battery management system during the charging process. When the module is charged at 4.5 A for about 805 s, each cell of the battery has reached the balancing state. Finally, the testing results validate that the modular battery management system proposed in this paper can effectively manage the battery balancing of each cell in the battery module, battery module overcharge, over-discharge, temperature protection, and control.

Design of Remote Monitoring System for Lithium Battery Operating Statu

“…The initialization consists of the reset pulse sent by the main control chip and the response pulse sent by DS2438. The reset pulse informs DS2438 to initialize, and the response pulse informs the master chip DS2438 that initialization has been completed [16]. When the main control chip receives the response pulse of DS2438, it will send a ROM command to control DS2438 to access a specific function.…”

Multi‐parameters dynamic scheduling with energy management for electric vehicle charging stations

“…Compared with the system proposed by Cherukuri et al., the modular BMS for electric motorcycles proposed by Chen et al. [18] has more functions. In addition to collecting the three types of data above, the system can also control the battery protection switch to protect the safety of the battery module in the charging and discharging process.…”

“…The BMS is highly customised when used, and different scenarios make the BMS very different. Common application scenarios include EVs [16,17], electric motorcycles [18], aviation planes [19], underwater robots [20] etc., most of which are small-capacity applications. On the grid side, the BESS is already used [21].…”

Analysis of power quality and economic worthiness of electric motorcycle charging in a residential electrical system

“…Governments of many countries support and encourage the use of EMCs. In addition, several researchers have suggested improvements in EMC models, including the use of an electric motor rather than an internal combustion engine [2], development of a stable charge-discharge battery management system and reduction in noise [3], and development of a swapable battery system for flexibility in use [4][5][6].…”
