We Tested JBD, Daly & JK BMS After the E-Rickshaw Hack — The Vulnerability Is in the Hardware We recently came across reports covered by news outlets about electric vehicles, specifically e-rickshaws, being remotely hacked and stalled in the middle of busy roads. The attackers were using Android apps, some of which were available on the Google Play Store under names like BAT-BMS, Epoch Li-on and Overkill Solar. These apps were apparently able to connect to some specific brands of the… |

IoT based Lithium Battery Monitoring System for Solar Installation using ESP8266 The aim of this project is to monitor a Lithium Battery Bank remotely in a solar installation. It traces current individually for each Battery Pack. It also communicates with solar charger and calculates live values of power going to home and battery bank. It includes a web server with charts, internal historical data, and optionally can also upload data to Thingspeak and… |

Cell Balancing Techniques and How to Use Them A nominal lithium cell is rated for around 4.2V only, but in its applications like EV, portable electronics, laptops, power banks etc we require a lot higher voltage than its nominal voltage. This is the reason why designers combine more than one cell in series to form a battery pack of higher voltage values. As we know from our previous Electric Vehicle battery article,… |

Battery Management System (BMS) for Electric Vehicles On 7th January 2013, a Boeing 787 flight was parked for maintenance, during that a mechanic noticed flames and smoke coming from the Auxiliary power unit (Lithium battery Pack) of the flight, which is used to power the electronic flight systems. Efforts were taken to put the fire off, but 10 days later before this issue could be resolved, on 16th January another battery… |

All you want to know about Electric Vehicle Batteries The speed, mileage, torque and all such vital parameters of an electric car solely depends on the specification of the motor and the battery pack used in the car. While using a powerful motor is no big deal, the problem lies with designing a Battery Pack that could source enough current for the motor for long time without degrading its lifespan. To cope up with the voltage… |

An Engineer's Introduction to Electric Vehicles (EVs) According to a forecast by International Energy Agency, the use of Electric Vehicles will grow from 3 million to 125 million by the year 2030. That is almost 41 times of what it is today, with the increasing demand of fossil fuel and problems with pollution it seems most likely to happen. Owing to that, all major IC Engine Car manufacturers like Ford and GM are slowly… |
