CATL Unveils Dual Electric Range Extension Battery

CATL has unveiled its dual-electric range extension battery and latest-generation heavy-duty battery-swapping solution in Beijing on 23 October 2026 to accelerate the electrification of road freight transportation. The modular heavy commercial vehicle powertrain pairs a chassis-mounted swappable pack with a secondary 77kWh behind-the-cab unit capable of 3C charging.

The Chinese battery manufacturer designed the dual-battery setup alongside its proprietary Qiji standardisation and infrastructure strategy. The technology addresses electric heavy-duty trucking economics, targeting commercial fleet concerns surrounding battery utilisation, operational overheads, and residual vehicle values.

Key Facts

How Does CATL Dual-System Power Redundancy Work?

CATL dual-system power redundancy pairs a swappable chassis battery with a behind-the-cab auxiliary pack, increasing main battery depth of discharge from 70% to over 95%. When main charge drops below 5%, millisecond switching transfers load to the backup battery, maintaining continuous power delivery without vehicle stoppage.

Conventional electric heavy-duty truck drivers frequently return packs to swapping facilities prematurely due to range anxiety. The secondary 77kWh battery eliminates premature swapping cycles, allowing logistics operators to consume virtually the entire stored capacity before visiting a Qiji station.

"While battery swapping has made energy replenishment faster and more predictable, concerns about battery utilisation, operating costs and residual vehicle value continue to affect fleet economics."

CATL dual-electric range extension technology transfers power delivery to a 77kWh backup battery within milliseconds once the main chassis battery drops below a 5% state of charge.

What Is the CATL 1+X Battery Architecture?

The CATL 1+X architecture decouples commercial vehicle energy storage into one standardised swappable main chassis battery and one customisable auxiliary range-extension battery. While the primary pack maintains full compatibility across the Qiji infrastructure network, the secondary pack can be configured independently for specific environmental or operational demands.

Fleet operators can customise the independent range-extension pack with ultra-high energy density chemistry, cold-climate low-temperature resistance, or ultra-high power output profiles. Both power units undergo technical upgrades independently across their lifecycle.

Under CATL 1+X architecture, a standardised Qiji swappable chassis battery operates alongside an independently upgradeable auxiliary battery tailored for power, density, or extreme climates.

How Does CATL Asset Management Lower Fleet Operating Costs?

CATL asset management separates battery ownership models, retaining the permanent behind-the-cab range-extension pack as a fixed vehicle asset while allowing operators to lease the standardised main chassis battery. Fleets can dynamically adjust leased battery volume to align with seasonal haulage demands, lowering standing rental costs.

Retaining an onboard 77kWh pack reduces vehicle reliance on immediate swapping station access during transport routes. During periods of lower logistics activity, commercial transport operators can surrender leased main packs to minimise ongoing fleet expenditure.

Commercial vehicle operators can lease the primary Qiji swappable battery based on seasonal freight demand while retaining the auxiliary range-extension pack as a permanent vehicle asset.

Who Is This For in Malaysia?

This heavy-duty transport technology targets commercial road freight fleet operators seeking lower operational costs and flexible battery utilisation across long-haul logistical routes. The dual-system setup directly resolves vehicle downtime and residual value risks associated with standard electric commercial trucks.

Local Malaysian distribution, local pricing in RM (Ringgit Malaysia), vehicle assembly status (CKD or CBU), and domestic road tax or infrastructure compatibility have not been announced.

The dual-electric range extension battery system is designed for commercial heavy-duty freight fleets seeking to lower battery rental expenses and eliminate premature charging stops.

Common Questions

How low can the main battery state of charge drop before swapping?

The main battery can be depleted to less than a 5% state of charge before swapping. The onboard secondary battery increases the main battery depth of discharge from 70% to over 95% without risking sudden power loss on transit routes.

What are the technical specifications of the range-extension battery?

The behind-the-cab range-extension battery is currently equipped with a 77kWh capacity and features 3C charging capability. Optional configurations include low-temperature resistance for cold climates, ultra-high energy density, or ultra-high power output depending on fleet deployment requirements.

Has local pricing or availability been announced for Malaysia?

Local pricing in RM (Ringgit Malaysia), local distributor appointments, and Malaysian release schedules have not been announced. The technology was unveiled in Beijing focusing on standardising heavy-duty electric trucking infrastructure and flexible commercial fleet leasing models.
