Behind every quotationis a set of data your engineers can re-check
Selection logic, service life, failure diagnosis, safety validation and the export compliance route are all published here, so procurement decisions rest on traceable engineering data rather than a supplier's assurances. This library is the evidence base behind every TIANQIU quotation, warranty and market-access document.
verifiedEvery figure comes from laboratory bench records or overseas field operation; raw curves, test reports and original certification scans are available per project

Where this library's data comes from
Bench testing, vibration duty data, standard duty cycles and overseas fleet operation together form the evidence base for this library.
Specification notice:The figures above are engineering reference values. They may differ with production batch, configuration and actual duty cycle, and the percentages for life, efficiency, availability and coverage are engineering estimates and bench references. Contact us for the detailed specification sheet.
Where the data is produced
From thermal-runaway and fire-safety practice to BMS commissioning and the 48V / 60V / 72V platform comparison — each conclusion states the basis it rests on.



Selection and electrical matching
Get the voltage platform, real capacity, charger match and BMS communication right first, and the vehicle stops coming back from gradients, fast charging or swap-cabinet commissioning.
48V / 60V / 72V voltage selection
Derive the working voltage platform from payload, gradient and daily distance, and avoid the three critical mistakes made when upgrading a pack.
Open the selection guidearrow_forwardReal Ah capacity and range estimation
Move from nameplate Ah to genuinely usable capacity, folding depth of discharge (DoD), high-temperature losses and real vehicle consumption into one credible range figure.
Estimate real rangearrow_forwardCharger matching and fast-charge safety
How charger voltage platforms, constant-current constant-voltage curves and BMS communication protocols must line up to avoid over-temperature and nuisance protection lockouts during fast charging.
Check charger matchingarrow_forwardBMS selection and CAN bus
How to size continuous current, over-current steps and MOSFET withstand voltage, plus CAN 2.0B message definitions and how they map to the instrument cluster and charger.
Open BMS selectionarrow_forwardBMS host software and protocol centre
Host software, CAN / RS485 messages and swap-cabinet communication protocols, with the diagnostic paths for the problems that actually appear on site.

Cycle life, thermal propagation isolation, factory quality control and failure diagnosis in extreme climates decide whether the fleet still runs full shifts in year three.
Cycle life and SOH whitepaper
Why workshop packs die at 300 cycles while automotive cells reach 3,500 — seven fade mechanisms compared, with temperature and impedance plots.
