How to Size the Battery for Your Forklift Fleet Author: Max Khabur, Marketing Director ENEROC USA A practical guide to moving a warehouse fleet from propane to electric trucks: the benefits of switching and the four variables that determine what size battery the job requires. Why switch Maintenance. An internal combustion engine needs oil changes, filters, spark … Read more
ATI’s 2026 Target Matrix vs the 2021 NASA Baseline Back in 2022 we covered NASA’s targets for electrified aircraft propulsion, which were deliberately broad: a single system level specific energy figure of 400 Wh/kg, a general expectation of “1000’s of cycles”, and a note that power demand would spike hard during takeoff and landing. That … Read more
Can we find a battery pack from the Battery Pack Database, using a limited dataset of 642 packs. Something that might get you an idea as to what you should be looking at? Note: if you just want to search based on useable energy just delete the values in all of the other search boxes. … Read more
With so much data now available in the Battery Pack Database it is interesting to look at Cell to Pack Mass Ratio by Chemistry and Format. Note that for this analysis we have excluded all of the BESS packs as they tend to not be as mass sensitive as mobile applications. The fixed lines showing … Read more
The 12V system voltage limits used across the automotive industry come from LV124, the specification that defines the operating voltage range every 12V component must survive. It sets out Vmin and Vmax limits for different classes of function, covering everything from cranking dips during engine start to steady-state running voltage. Note: the 6V cold engine … Read more
Most cell selection still begins with datasheets, because they are the only information engineers can easily access early on. That is understandable, but it is also why teams spend months testing “promising” cells that later fail in a real pack. The root issue is simple: a cell is not a battery pack. Effective selection requires … Read more
1. Introduction Ola Electric has rapidly positioned itself as one of the most influential players in India’s electric two-wheeler revolution. Beyond the scooters themselves, a critical pillar of Ola’s strategy is its in-house battery technology, which serves as the backbone of its product roadmap and cost leadership ambitions. The company has invested heavily in vertical … Read more
In the battery application world everyone is always looking for power vs energy density. Wanting the maximum of both. However, as we know from a comparison of power vs energy cell design it is nearly impossible to have both. In simple terms the energy cell has thicker layers of active material, thinner current collectors and … Read more
For most simple peak power calculations we will be interested in the Direct Current Internal Resistance (DCIR) value for a new cell at 50% SOC (25°C, 10s), Open Circuit Voltage (OCV) and minimum voltage. Note: this is just an estimation and this needs to be compared to the manufacturers specifications and tested values. However, as … Read more
In the first instance it is all about requirements. What are the hard points, the inviable parameters? My first thoughts are around these headings: This post has been built based on the support of and sponsorship from: Quarto Technical Services, Eatron Technologies and About:Energy Initial sizing is around Electrical and Thermal. The Battery Calculations Workbook has some great tools to … Read more
