Direct manufacturer-sourcing solutions engineered for safety, reliability, and advanced intelligent communications (CAN/Bluetooth/NTC).
In the rapidly evolving micro-mobility ecosystem, the Battery Management System (BMS) acts as the central brain of light electric vehicles (LEVs). Standard off-the-shelf boards no longer satisfy the safety, range, and communication demands of modern fleet operators and consumer e-bike manufacturers.
Modern e-bikes require constant synchronization between the drive motor, the central display, the battery, and mobile apps. We engineer state-of-the-art CAN Bus, UART, and Bluetooth Smart BMS modules that enable seamless data telemetry, enabling OTA diagnostics and real-time state-of-charge tracking.
Thermal runaway prevention is critical for global standard compliance. By integrating custom NTC thermistors, our BMS boards detect localized hot-spots within the battery cells, automatically shutting off current during discharge or charging to secure the pack from hazards.
We work closely with global design agencies to ensure our BMS products enable pack designs compliant with UL 2849, EN 15194, and UL 2271 frameworks, addressing rigid regulatory hurdles across Europe, North America, and beyond.
Off-the-shelf lithium protection boards struggle with custom pack geometries and specialized current thresholds. Custom BMS engineering allows manufacturers to optimize battery chemistry efficiency, integrate custom safety switches, deploy self-heating functions for cold environments (as seen in our 23S 60A Bluetooth Heating BMS), and extend cycle life by up to 30% through precise cell balancing algorithms.
Shenzhen Litongwei Electronic Technology Co., Ltd. operates state-of-the-art automated manufacturing facilities. We align cost efficiencies with rigorous quality control pipelines to deliver scalable OEM/ODM solutions.
Our production facilities utilize modern high-speed pick-and-place lines and 12 dedicated PCBA processing lines. High density circuit integration and fine-pitch component placement are standard, ensuring minimal defective rates for our micro-inverters and large format protection boards.
Quality control is maintained using advanced automated optical inspection (AOI), circuit test platforms, and environmental test chambers. Full MES tracking is deployed, supporting comprehensive quality traceability from incoming chipsets to finished BMS modules.
We hold over 100 patents in the lithium-ion battery management segment, and we actively co-develop circuits with global partners to protect intellectual property and mitigate third-party patent infringement risks.
Since 2005, Litongwei has evolved from a digital BMS workshop to an industry leader in smart green energy solutions.
Established in 2005, we commenced research and manufacturing of digital Battery Management Systems (BMS). By 2006, the product scope expanded into electric vehicle power systems. ISO9001 and ISO14001 quality certifications were obtained in 2007 and 2009 respectively, establishing a solid manufacturing baseline.
During this era, the company secured 8 utility model and design patents while building the mobile power bank product lines. In 2012, we officially founded the Litongwei Technology Research Institute. Recognitions followed, including the Del New Energy Quality Excellence Award (2014) and the Gold Partner designation from Gaogong Lithium Battery (2015).
We updated our ISO systems, achieved the strict IATF16949 automotive quality management system standard in 2018, and completed the deployment of MES software for automated storage and distribution systems. Awarded the Innovation Award by the Guangdong Battery Industry Association in 2019, Litongwei was recognized as a premier brand for two-wheeled vehicle protection boards in 2020.
Embracing IoT, Cloud API support, and Industry 4.0 paradigms. Litongwei continues to innovate intelligent protection boards equipped with CAN/Bluetooth communication, supporting remote updates, real-time parameters settings, and custom application integration for micro-mobility fleets.
Meeting international standards is critical when sourcing Ebike BMS systems. Here is how we align design cycles with regional safety regulations.
For E-bikes targeting the US and Canadian markets, passing UL 2849 is vital. Our custom BMS architecture features double-fault protection circuits, dedicated hardware over-voltage triggers, and isolated charging layers to meet the rigorous evaluation standards of third-party test labs (such as TÜV, UL, and SGS).
Under EN 15194, E-bikes require sophisticated functional safety checks. Our smart BMS models feature dynamic cell-balancing limits and multiple NTC points to constantly monitor the thermal state of the pack, ensuring full compliance with the European Machinery and EMC directives.
For modern sharing fleets, downtime is expensive. We develop advanced cloud-management APIs that connect with our Bluetooth and cellular modules. Fleet operators can monitor real-time State-of-Health (SoH), log errors, and upgrade firmware remotely, lowering technical and service costs.
Our continuous pursuit of engineering excellence has earned us long-term partnerships with leading global technology brands.
We proudly collaborate with market leaders including Huawei, Lenovo, Desay, Guoguang, Sunwoda, Eve Energy, Guoxuan High-tech, and other premium global enterprises.
Expert answers on technical requirements, ordering processes, and supply configurations for global buyers.
High-performance protection boards engineered for 10S to 23S battery configurations, featuring advanced communication options.
