Abstract

This paper discusses a 58 volt battery voltage control system for electric vehicles using the Blynk application.The research successfully monitors the amplitude of the battery voltage. Additionally, it includes the capability to controlthe battery via an SSR relay, which is connected to the NodeMCU ESP8266. The Blynk application displays both theamplitude and the percentage of the battery voltage. The NodeMCU ESP8266 has demonstrated reliable performance,maintaining a stable connection as long as it is connected to the internet. The average voltage discrepancy shown on theBlynk application is 0.74%. The SSR relay disconnects the power supply to the electric vehicle when the battery voltageapproaches 46.3 volts or when the battery capacity percentage drops to 0.16%. This system ensures that the battery ismanaged effectively, preventing over-discharge and potential damage by disconnecting the load at critical voltage levels
