HAOSEN

HAOSEN's company page describes the planning, design, assembly, commissioning and integration of intelligent production lines. Its automotive work covers lithium batteries, fuel cells, motors, electric drives and conventional powertrains, with separate MES and logistics categories. In your enquiry, name the battery project and the software interfaces you want quoted, so the offer covers your line and leaves out the rest of the portfolio.

HAOSEN builds lines for vehicle makers: lithium battery modules and packs, fuel cells, motors and electric drives, conventional powertrains, plus MES and logistics systems. A prismatic module line from an integrator like this usually runs cell loading and checking, cleaning, gluing or insulation, stacking and compression, busbar laser welding, insulation tests and end-of-line testing.

A 2026 regulator notice about the company's acceptance paperwork is a good reason to be strict about records. Ask for acceptance criteria for every station, a dated and signed report for each, and a line test with your own cells. The acceptance testing page explains how to divide those checks between the factory and your site.

A notice from the CSRC Dalian bureau dated May 18, 2026 names revenue-related internal-control issues at HAOSEN. It mentions missing dates on some customer acceptance reports and wording errors in reports for individual projects. The notice is about reporting and controls; it makes no finding on machine quality or on this module line.

For your purchase, keep full, dated acceptance reports for each station and for the line. Each report should name the configuration tested and list any open items. Ask HAOSEN what corrective steps it has taken since the notice.

Each source below is the maker's own page or a public record, with the date it was checked. Ask the factory to confirm the figures for your order in writing.
