Elevators are the core transportation facilities in buildings. Their operational safety and emergency support directly affect public security. As the safety line of defense during sudden power outages, emergency backup power supplies critical energy for emergency operations such as elevator leveling and door opening. This imposes stringent requirements on the safety, stability, and rate performance of backup batteries.
With 24 years of expertise in the battery industry, BPI — a national-level specialized and sophisticated enterprise — has developed the SC-series high-rate discharge Ni-MH batteries based on core technological accumulation. Featuring high safety, high rate performance, long service life, and wide temperature adaptability, these batteries have become an ideal solution for elevator emergency starting power supplies, laying a solid power foundation for elevator emergency support.
The core demand of elevator backup power is to deliver instant strong power during sudden outages to enable a quick response of the emergency system.BPI SC high-rate Ni-MH batteries come in two series: the medium-rate P series and high-rate XP series, with a capacity range of 2000–4200 mAh. They support 3.0–10.0C high-rate discharge, releasing stable and powerful power the moment power cuts off. This ensures fast elevator leveling and door opening, gaining critical time for safe passenger evacuation and eliminating the risk of passengers being trapped due to insufficient power.
The batteries also support 0.5–1.0C high-rate charging, enabling rapid recharging and quick restoration to backup status after emergency use. This meets the elevator backup power requirement of instant availability and fast recovery, supporting 24-hour uninterrupted backup for building elevators.
Safety is the top priority for elevator backup batteries. The enclosed elevator shaft and fluctuating temperature demand much higher safety performance than ordinary applications.BPI SC batteries are the only Ni-MH product in the industry with independently developed explosion-rotection patent + explosion-protection system patent, both fully applied in mass production. The structural design fundamentally eliminates safety risks under extreme conditions such as short circuit, high temperature, and overcharge.
Rigorous testing confirms that the batteries remain 100% safe — no explosion, no leakage, no overheating — even under fully charged short-circuit and 150°C extreme temperature rise tests. This completely satisfies the high safety standards for elevator backup power.
Buildings are widely distributed, and large temperature differences between regions and fluctuations in elevator shafts demand high environmental adaptability. Meanwhile, elevator backup batteries operate in long-term standby with occasional discharge, requiring strict cycle life and cell consistency.
BPI SC batteries work stably in a wide temperature range of −20°C to +65°C, maintaining reliable discharge and standby performance in elevator shafts of all building types.
Cycle life exceeds 1000 cycles under IEC standards
Cycle life reaches over 400 cycles under 0.5C fast deep charge/discharge
These features meet the long-term standby and repeated charge/discharge needs of elevator backup power, greatly reducing later replacement and maintenance costs.The batteries offer excellent cell consistency and support 2.4V–48V series connection and 2–5 parallel groups, allowing flexible configuration for backup systems of different elevator brands and models without complex modification, delivering strong adaptability.
As a world-renowned battery OEM/ODM manufacturer, BPI holds six authoritative production certifications, including ISO9001, ISO14000, IATF16949. The SC batteries have obtained product certifications from multiple countries and regions, such as CE, CB, PSE, KC, complying with mainstream global market access standards.
From raw material selection, cell R&D and manufacturing, to quality control inspection and finished product delivery, BPI implements a full-process, high-standard quality management system to ensure stable and consistent quality of every battery. This provides standardized, high-quality power solutions for elevator backup systems, making BPI a core partner of many elevator brands.
With 24 years of technological accumulation, BPI has forged robust product strength. Targeting the public-safety-critical scenario of elevator backup power, BPI SC high-rate Ni-MH batteries precisely solve the three core pain points of power, safety, and adaptability, safeguarding building transportation safety with advanced technology.
In the future, BPI will continue to focus on the emergency energy storage battery sector. Leveraging the R&D capabilities of a national specialized and sophisticated enterprise, the company will keep optimizing product performance to deliver higher-quality and more adaptable energy solutions for the elevator backup power industry, establishing a reliable power benchmark in the emergency energy storage field.
