from chemistry to pack
Why are we moving to higher voltage packs? We know that the battery cell is not a perfect current source as it also has an internal resistance. Symbolically we can show a cell with the internal resistance as a resistor in series. Rint is the DC internal resistance, sometimes abbreviated as DCIR. The DCIR is not … Read more
There can be a number of reasons to do an Emergency Shutdown of a battery pack and a number of approaches to this. Hence interesting to layout and discuss this topic. It should be noted that we are discussing the BMS opening the contactors. The main reasons for an emergency shutdown are: Each of these … Read more
There are a number of reasons to estimate the charge and discharge current limits of a battery pack in real time: Hence this is a key function of the Battery Management System (BMS). The difficulty is that the current limits are dependent on a number of factors, for the cell alone we should consider the … Read more
In this Article you will the details about the Rivian R1T Battery pack and Module Construction, Standard Specification, Key Pack Metrics.
In this Article, we will compare different Cylindrical Cell Sizes used in electric Vehicles. 4680 vs 21700 vs 18650.
Equations and Calculator for DC to DC Converter: Buck, Boost and Bidirectional Buck and Boost Converter. Have Fun
In this article, we will look at the Battery Module Production. There are 7 Steps for Battery Module Production.
Current from the Grid (AC) goes through EVSE (Charging Station Either Level 1 or 2) through a connector to the On Board Charger. The Onboard Charger rectifies or converts the current into DC and sends it via the Battery Management System (BMS) to the Battery Pack
Batteries are the heart of an Electric Vehicle but the Battery Management System is more like the brain which keeps the Heart pumping out electricity to the Motor safely and at required output. Electric
