Reliable hardware battery protection boards optimized for rugged industrial and light e-mobility duty cycles in Western Europe.
As home to the second-largest seaport in Europe and one of the largest petrochemical clusters globally, Antwerp represents a demanding industrial landscape. The shift towards electrification of maritime handling machinery, heavy-duty AGVs (Automated Guided Vehicles), portside container transporters, and local smart grid storage setups is driving an unprecedented need for extremely robust Hardware BMS (Battery Management System) architectures.
Operating in environments that feature high humidity, salinity, and strict explosive atmosphere safety standards (ATEX zones) requires battery packs that cannot afford component failure. Standard consumer-grade protection boards are inadequate for the rigorous load cycles of warehouse automation in the Antwerp logistics hub.
Our industrial-grade hardware BMS provides real-time overcurrent, short-circuit, and cell-balancing capabilities with low-latency protection profiles. By using high-performance integrated circuits (ICs) and thick copper PCB layouts, we supply solutions designed to withstand the harsh, continuous operations of European heavy logistics.
Detailed insight into cell protection, thermal margins, and redundant circuit designs optimized for multi-cell series battery arrays.
Cell capacity mismatches lead to reduced pack lifespan. Our BMS integrates precision bypass resistors to discharge high-voltage cells during the top charge phase. For heavy material handling applications, we design high-efficiency balancing algorithms that equalize cell voltages up to 200A discharge rates.
Multiple NTC thermistors are strategically routed to monitor cells, power MOSFETs, and ambient temperatures. This provides instantaneous system shutdown before critical temperature levels are reached, preventing catastrophic failures.
Designed with industrial-grade AFE ICs, our BMS structures read individual cell voltages with millivolt accuracy. Combined with secondary hardware protection loops, this ensures failsafe operation even if the primary microcontroller experiences communication loss.

"Technology as King, Efficient Service"
LITONGWEI has always adhered to this philosophy in all aspects of production and operations. Our vision is to become a leading provider of intelligent green energy management solutions, embracing environmental sustainability. Start with LITONGWEI!
Through our dedicated efforts in high-power design, robust heat-sink architectures, and rigorous QC workflows, we strive to deliver hardware protection boards that fulfill European environmental standards and safety directives.
Litongwei's partners include major industry brands who have collaborated with us for many years.
A full portfolio of micro-inverters, multi-cell BMS, and smart wearable energy modules engineered for stable operation under high electrical load profiles.
Essential information regarding standards, custom orders, and integration for European system integrators.
Our company is ISO9001 and ISO14001 certified. We also hold IATF16949 automotive quality management system certification. Our products comply with European directives, including CE and RoHS standards, which are essential for industrial operations in the European Union and the Antwerp region.
Our Smart Heating BMS has an built-in temperature monitoring algorithm. In cold climates (such as Belgian winter port operations), if the temperature falls below a set threshold, the BMS routes charging current to run a custom-designed heating film before charging begins. This prevents the formation of lithium dendrites, ensuring safe charging cycles down to -20°C.
We support multiple configurations including CAN bus (CANopen, J1939), RS485 (Modbus RTU), and basic SMBus/I2C connections. These systems allow real-time telemetry output of State of Charge (SOC), State of Health (SOH), individual cell voltages, and thermal probe data straight to industrial dashboards and PLCs.
Yes. For example, our LTWSmart Micro Inverters feature a fully potted, weatherproof IP67 structure. We also support custom-fitted aluminum enclosures and conformal coating processes on PCBAs, which protect electronic components against salt mist corrosion in maritime hubs like Antwerp.
