The 2026 Guangdong-Hong Kong-Macao Greater Bay Area Auto Show kicked off in Shenzhen on May 29, drawing global attention to the latest electrification innovations. Among the highlights, CALB and Harmony Intelligent Mobility made a joint appearance, unveiling their collaborative safety framework for the Huawei Giant Whale Battery Platform. As a core co-builder of the platform, CALB demonstrated its full-spectrum battery safety technologies and achievements in full-standard AI-driven intelligent manufacturing.

Notably, CALB is one of the official drafters of China’s new national battery safety standards. The company has actively participated in battery standard certification for multiple Harmony Intelligent Mobility models, with its products not only fully complying with but also exceeding the stringent requirements of the latest national regulations. According to CALB’s technical team, the battery system achieves an optimal triad balance—safety, driving range, and residual value retention—delivering tangible benefits to both OEMs and end consumers.

⚡ Three pillars of all‑round protection

• √ Full‑stack safety design — 15 robust protective layers effectively prevent internal short circuits, thermal runaway, piercing, deformation, high‑temperature stress, abrasion, and corrosion.

• √ Full‑standard AI intelligent factory — 100% on‑site X‑ray inspection for every single cell, backed by over 200 technological upgrades and AI‑powered visual detection for zero‑defect quality.

• √ Full‑lifecycle safety guarantee — Cloud Battery Manager with more than 200 sensing nodes enables millisecond‑level early warnings and 7×24 real‑time monitoring of each cell’s status.

Centered on the design philosophy that “Safety is the ultimate luxury”, the Giant Whale Battery Platform—co‑engineered by CALB and Harmony Intelligent Mobility—sets a new benchmark for EV battery safety. The integration of full‑stack hardware protection, AI‑driven production line inspection, and cloud‑based lifecycle management creates a closed‑loop safety ecosystem that addresses the industry’s most critical pain points.

During the auto show, CALB executives highlighted that the partnership with Harmony Intelligent Mobility goes beyond component supply—it is a deep strategic collaboration on system‑level safety standards. With the new national battery safety standards taking effect, CALB’s early involvement in drafting and testing gives it a first‑mover advantage in regulatory compliance and performance optimisation.

Industry analysts note that the combination of CALB’s manufacturing expertise and Harmony’s intelligent vehicle architecture, together with Huawei’s battery platform, represents a powerful synergy. The real‑time cloud BMS, in particular, is seen as a differentiator, offering predictive analytics that can pre‑emptively identify anomalies before they escalate.

INSIGHT   The Giant Whale Battery Platform is expected to power several new models in the second half of 2026, with CALB’s production lines already ramping up for mass delivery. The partnership underscores a broader industry shift toward “safety‑first” electrification, where regulatory rigour and AI‑enabled quality control become competitive differentiators.
