A Side-Extraction Lithium Pack Fits an Existing Stuttgart Forklift Fleet
A Stuttgart automotive-parts plant commissioned lithium packs around its existing side-extraction battery layout, preserving the handling arrangement for 34 production-line forklifts.

A conversion constrained by the existing trucks
An automotive-parts factory in Stuttgart used 34 forklifts to supply production lines. Its existing 48 V, 625 Ah lead-acid installation used a DIN-format side-extraction box. Changing the vehicle handling arrangement would have added disruption for drivers and maintenance staff.
The customer therefore specified the replacement around the existing 830 × 780 × 620 mm envelope, side-extraction method and lifting interfaces.
The battery was adapted to the fleet
HUA-X supplied 460 Ah side-extraction lithium packs for the plant's 48 V forklift platform. The project matched the existing box dimensions and handling points so drivers could continue removing and installing the box using the established procedure.
The conversion was accompanied by an assessment of the charging area and changes to fire separation. Physical fit was considered together with the site's charging arrangement.
Reduced electricity use without changing the handling routine
The project recorded a 19% reduction in daily electricity use. At an electricity-price basis of €0.19 per kWh, annual savings across 34 trucks were approximately €8,900.
The central result was a fleet conversion that fitted the production environment. Matching the replacement to the existing truck and battery-handling equipment helped the customer change the energy system while preserving an established operating routine.
