from chemistry to pack
Every junction between two different metals in a sense-wire path is a small, unwanted thermocouple. If there’s a temperature difference across it, it generates a real voltage that a precision voltmeter cannot tell apart from the signal it’s supposed to be measuring. 1. A Junction You Didn’t Design Is Still a Junction Anywhere a copper … Read more
Based on the analysis of the Battery Energy Storage System (BESS) applications, there is a clear correlation between the scale of the application and its nominal voltage. Key Findings: NOTE: this analysis has been done using AI to look at the Battery Pack Database. Hence it is based on the data we have provided along … Read more
In school, we learn that the voltage across circuit components in parallel is the same, and the current is split between them according to their resistances. For components in series, the current through each is equal and the voltage drops off. In a simple model, the total capacity of a battery pack with cells in … Read more
Update: Now that Tesla Cybertruck has been launched and first delveries/bookings being confirmed. We can update the article and benchmarking based on the data available from the websites and various forums. We are now seeing them on the road and buzz is going around with various video reviews. Recent Q2 Earnings call gave us the … Read more
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
India’s number one selling EV in 2022. Tata Nexon EV Prime 30.2 kWh and Max 40.5 kWh battery pack benchmarking.
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
