In the lithium‑battery industry, “safety” carries immense weight. Consumers expect not only long endurance and fast charging, but also the peace of mind that comes with zero hidden risks. Ginkgo Battery understands this well: from the core cell to the intelligent management system, it builds layer upon layer of safeguards—using brand‑new, A‑grade cells sourced from leading manufacturers and pairing them with a self‑developed BMS protection board. With a safety philosophy that emphasizes both internal and external robustness, Ginkgo redefines the reliability standards for power batteries.
I. Rigorous Cell Selection: Ensuring Quality from the Source
The battery cell is the “heart” of a lithium‑ion battery, and its consistency and stability directly determine the safety limits of the battery pack. To cut costs, many brands on the market use Grade‑B or even refurbished cells, which suffer from rapid capacity fade and uneven internal resistance—risks that can easily lead to overheating and short circuits over time.

Criteria for selecting Ginkgo batteries:
The battery cells are brand-new, Grade-A cells from a top-tier manufacturer, ensuring that every cell meets factory‑grade A standards.
Six‑stage screening process: After purchasing the battery cells, they undergo capacity grading (±1% accuracy), internal resistance testing (with a variation of less than 0.5 mΩ), X‑ray nondestructive inspection, high‑temperature aging (cycled at 85°C for 48 hours), self‑discharge rate screening (less than 3% per month), and airtightness verification.
Battery Safety Passport: Each battery pack is equipped with a unique QR code, enabling traceability of its production batch, test reports, and even raw material suppliers, thereby preventing the use of substandard components.
Five-layer safety protection: Structural safety: 3-mm thickened aluminum alloy casing
Process Safety: Full potting process, fully automated laser welding,
Self-developed Ginkgo BMS smart protection board: triple hardware and software safeguards plus fuse‑based active circuit breaking.
Material Safety: All materials inside the battery pack are flame-retardant.
Supply Chain Security: Battery Passport and Cell Traceability

Measured comparative data:
Cycle life: After 2,000 cycles, the capacity retention of Grade A cells exceeds 85%, whereas that of Grade B cells is only 70%.
II. In-House Developed BMS: Equipping Batteries with the “Most Powerful Brain”
If the battery cell is the heart, then the BMS (Battery Management System) is the central nervous system. Conventional BMSs typically rely on off-the-shelf solutions, which struggle to precisely match the unique characteristics of different battery cells and feature simplistic algorithms that fall short of handling complex operating conditions. Ginkgo Battery has independently developed a proprietary BMS, with end-to-end customization from hardware to software, delivering “hands‑on” safety management and control.
Dual‑pronged synergy: Security performance that’s greater than the sum of its parts—when top‑tier A‑grade battery cells meet Ginkgo’s proprietary BMS, safety protection shifts from isolated breakthroughs to systematic, coordinated defense. The battery pack complies with the GB/T 31485 standard for electric vehicle battery safety and has demonstrated no ignition or explosion in tests such as nail penetration, compression, and drop impact.

Electric vehicle owner: “Range reduction in winter is a common issue, but the Ginkgo battery’s self-heating feature gives me 50 kilometers more range than my friend’s car.”
Outdoor enthusiast: “Riding through torrential rain and wading through water, the battery still functioned perfectly after being submerged for half an hour—IP67 protection is no exaggeration.”

There are no shortcuts to safety—only relentless dedication to superior materials and cutting-edge technology.
Ginkgo Battery firmly believes that true safety cannot be achieved through marketing hype—it stems from the rigorous screening of every single cell and the meticulous refinement of every line of code. Choosing Ginkgo means not just opting for a battery, but embracing a steadfast commitment to nipping danger in the bud. With top-tier cells, we uphold the safety baseline; with proprietary technology, we safeguard the everyday lives of people.
