Fleet ESG reporting increasingly requires lifecycle CO2e analysis of installed equipment, not just operating-phase emissions. The 200 Ah LFP battery in the Vethy VS02 PRO is a meaningful capex and a meaningful end-of-life consideration. This page walks through embodied CO2e estimation, cycle life expectations, second-life options, and the recycling pathway through Redwood Materials, Northvolt Recycling, and Li-Cycle. The intent is to give fleet sustainability teams the inputs they need for ISSB IFRS S2, CSRD ESRS E5 (Resource Use and Circular Economy), and customer-facing circular-economy claims.

Embodied CO2e of LFP battery

Peer-reviewed lifecycle assessment of LFP battery cell manufacturing (Argonne National Laboratory GREET model, Sweden IVL meta-analysis, others) puts embodied CO2e at 60-90 kg CO2e per kWh of cell capacity, with the range driven by manufacturing location grid intensity. A 200 Ah, 25.6V LFP pack is ~5.1 kWh and therefore approximately 306-459 kg embodied CO2e at the cell level, plus ~50 kg additional for pack-level enclosure, BMS, and balance of system. Total embodied CO2e per Vethy VS02 PRO LFP pack: ~356-509 kg CO2e. Versus the 4-6 tonnes CO2e/year operating savings from idle reduction, the embodied carbon is recovered within 1-2 months of operation.

Cycle life and operating service life

LFP chemistry has high cycle life relative to other lithium chemistries — 3 000-5 000 full cycles to 80% capacity retention under typical operating conditions. In Vethy VS02 PRO operating profile (one near-full discharge per 24-hour cycle, recharge from alternator during driving), this corresponds to 8-13 years of service life. Practical fleet experience suggests pack replacement is typically driven by tractor retirement rather than battery end-of-life — the LFP pack typically outlives the tractor first-life cycle of 5-7 years and is a candidate for second-life or recycling at tractor retirement.

Second-life options for retired packs

An LFP pack at 80% retained capacity from a retired tractor still has substantial usable energy and is a strong candidate for second-life stationary storage applications: workshop / warehouse / depot battery backup, solar self-consumption buffering, EV charging buffer, or telecom backup. Several US and EU fleets have begun building structured second-life programs: pack tested at retirement, certified for stationary use, deployed in fleet depot or sold to second-life integrators. The economic value of second-life capacity is 25-45% of new-pack cost. From an ESG perspective, this is a clear ESRS E5 circular-economy story — the battery delivers two productive service lives before recycling.

Recycling pathway through Redwood, Northvolt, Li-Cycle

End-of-life LFP packs enter the lithium recycling stream through one of three primary North American/European processors: Redwood Materials (US, Nevada), Northvolt Recycling (Sweden, soon Germany), or Li-Cycle (US, Canada, Europe). All three operate hydrometallurgical processes recovering >95% of lithium, copper, and aluminum content. LFP chemistry has lower per-kg recovered-material value than NMC chemistry but the volumes are growing and gate-fee economics are improving. Vethy partners with regional recyclers offering documented chain-of-custody from pack pickup through material recovery, producing the audit trail fleet ESG teams need for ESRS E5 circular-economy disclosure.

Frequently asked questions

What is the embodied CO2e of the Vethy LFP battery?

Approximately 356-509 kg CO2e per pack including cell-level (60-90 kg CO2e/kWh × 5.1 kWh) plus pack-level (~50 kg). Versus 4-6 tonnes CO2e/year operating savings from idle reduction, embodied carbon is recovered within 1-2 months of operation.

How long does an LFP battery last in fleet service?

3 000-5 000 full cycles to 80% capacity retention, corresponding to 8-13 years in Vethy operating profile (one near-full discharge per 24-hour cycle). Pack replacement is typically driven by tractor retirement at 5-7 years rather than battery end-of-life.

What happens to the LFP pack at tractor retirement?

Strong second-life candidate at ~80% retained capacity for stationary storage applications: workshop battery backup, solar buffering, EV charging buffer, telecom backup. Economic value 25-45% of new-pack cost. Several fleets have built structured second-life programs.

How are end-of-life LFP packs recycled?

Hydrometallurgical recycling through Redwood Materials (US), Northvolt Recycling (Sweden, Germany), or Li-Cycle (US/Canada/Europe). >95% recovery of lithium, copper, aluminum. Vethy partners with regional recyclers offering documented chain-of-custody for ESRS E5 disclosure.
