What happened
CATL unveiled a dual-electric range-extension battery for battery-swapping heavy-duty trucks, and agreements covering 13,000 units were signed at the unveiling.S1 The system combines a standardized, chassis-mounted swappable pack from QIJI Energy with a 77 kWh backup battery installed behind the cab and designed for 3C charging.S1
The architecture, described as “1+X,” retains compatibility between the main battery and QIJI’s swapping network while allowing the range-extension battery to be tailored for energy density, cold-climate operation, or power.S1 CATL said conventional swapping trucks often return with unused capacity because drivers avoid deep discharge, so the backup system raises the main battery’s depth of discharge from about 70% to over 95% and permits a return below 5% state of charge.S1 Power delivery transfers to the auxiliary battery within milliseconds when that threshold is reached.S1
QIJI introduced 260# (432 kWh) and 300# (513 kWh) standardized swapping blocks alongside its existing 75# block, and reported a five-minute swap duration with a 99.99% first-time success rate.S1 Under its battery-as-a-service model, customers pay for net energy charged rather than energy discharged, preserving the value of energy recovered through regenerative braking.S1 QIJI said basic-plan users can reduce battery rental costs per kWh by up to 20%.S1

XAIPART take
Technical impact
XAIPART analysis: Separating the swappable traction pack from the auxiliary battery could give fleet engineers more freedom to tune cold-weather resilience or transient power without redesigning the entire energy system. Design teams should evaluate thermal control, rear-cab packaging, high-voltage interconnection, and protection coordination because the source did not disclose cell chemistry, maximum continuous output, or cold-weather charge performance.
Market impact
XAIPART analysis: The separate ownership model may reduce the capital tied up in the swappable pack, while seasonal leasing can let fleets match capacity to freight cycles. Procurement teams should compare the full operating package—energy charges, auxiliary-system servicing, station access, and downtime—with conventional fleet ownership rather than relying on the headline rental-cost figure.
Action
XAIPART analysis: Request sample specifications, safety documentation, station coverage, service intervals, and end-of-life terms for CATL and QIJI systems before adding them to an approved-vendor list. Fleets should also model route energy use, swap frequency, charger utilization, and auxiliary-battery replacement assumptions against their own duty cycles.
XAIPART Forecast
XAIPART expects CATL to disclose at least 1,000 units of the dual-electric range-extension system in commercial deployment within 12 months of the unveiling. If reported deployment remains below 1,000 units within that window, this forecast is wrong.XAIPART analysis
Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. Commercial timing, customer identities, deployment schedules, pricing, cell chemistry, power ratings, and cold-weather performance were not disclosed, and the available information comes from one source report.
