How DALY Builds Quality into Every BMS, from R&D to the Field

At DALY, our quality engineering team works hand in hand with R&D, supply chain, manufacturing and after-sales. We follow the Integrated Product Development (IPD) process step by step, and keep refining our products through testing and post-project review.

01Front-Loaded R&D Quality
Catch risks at the design stage

Design Quality Engineers (DQEs) in the R&D Quality Department act as the quality gatekeepers of the development phase, following each project through its full lifecycle:

02Real-World Validation
Testing that mirrors actual operating conditions

The R&D Testing Department is split into a Test Design Group and a Test Execution Group, working together as the “brain” and the “hands”:

We also test real-world conditions such as heavy-load start-up, high-current overcurrent, peak/off-peak power switching and engine load-dump surges, combined with environmental tests such as high and low temperature, vibration and electrostatic discharge, to match the wide range of conditions customers face.

Professional Test Equipment That Backs Up Validation

Quality validation relies on both hardware equipment and a management system. DALY operates 11 types of test equipment, including Nebula automated test cabinets, Agilent and Fluke measuring instruments, temperature and humidity chambers, and high-current loads, covering both conventional and extreme validation needs.

All DALY products are certified to ISO 9000, CE, RoHS and EMC, meeting common industry standards and global market access requirements.

03Manufacturing Control
Bringing design standards to the production floor

Every solution that R&D delivers must ultimately be realized on the production line.

DALY converts design requirements into executable documents such as SOP work instructions, PFMEA risk analyses and IPC process specifications, and applies process control to critical operations.

We also manage suppliers and perform incoming material sampling inspection, and run a risk assessment for every material change. From raw materials to finished products, this keeps mass-produced units consistent.

04Field Feedback
Driving quality iteration

Delivering a product to the customer does not mean the quality work is finished.

DALY collects device operating data through its cloud platform and receives feedback from frontline after-sales teams, then performs a root-cause review of every abnormal case in the field. The conclusions are shared with the R&D, quality and testing teams, who use them to improve designs and strengthen test cases. This closes the loop from the customer’s site back to R&D.

From risk prevention in R&D, to repeated validation in real-world scenarios, to strict control in manufacturing, to continuous tracking at the customer’s site, DALY builds quality into the entire BMS lifecycle. Every stage has standards, verification, feedback and improvement. DALY’s full-chain quality team safeguards every link of the BMS.
