Explore our core engineering catalog featuring advanced lithium-ion safety control systems, smart communications, and portable micro-inverters.
An in-depth review of advanced battery management systems (BMS), high-efficiency inversion, and intelligent cellular communication arrays.
Our BMS modules utilize intelligent micro-controllers to execute precision cell balancing. By neutralizing voltage deviations down to ±5mV, we mitigate localized hot-spots and extend LFP (Lithium Iron Phosphate) pack lifespan by up to 30%, ensuring reliable continuous discharges.
Designed for harsh environment installations, our Custom LTWSmart Micro Inverters feature an IP67-rated cast-aluminum casing. Fully sealed against high dust concentration and deep water immersion, they boast an outstanding 96.5% CEC efficiency rating.
Equipped with dual CAN bus, RS485, and low-energy Bluetooth (BLE) interfaces, our protection systems offer complete data visualization of state of charge (SoC), state of health (SoH), temperature profiles, and real-time remote cloud diagnostics.
Our BMS allows real-time local and remote configuration via custom apps. Users monitor parameters such as single-cell voltages, charge limits, and system temperature, enabling predictive maintenance prior to hardware malfunction.
Utilizing high-accuracy NTC thermistors, our BMS monitors cell surfaces and MOS switches continuously. If temperatures exceed predefined parameters, the system triggers automatic current throttling or relay disengagement.
From 13S to 23S multi-cell topologies, our standard and custom-engineered protection boards scale effortlessly to accommodate pack capacities ranging from 1kWh for light vehicles up to 20kWh+ for residential storage.
Deploying advanced automation, Industry 4.0 execution, and heavy capital investments to secure high-yield capacity.
With massive physical infrastructures located across our Shenzhen facility (13,000 square meters) and our Dongguan Huangjiang facility (27,000 square meters), Litongwei maintains vertical control over all PCBA manufacturing workflows. Equipped with 24 high-speed pick-and-place systems and 12 fully integrated SMT/PCBA production lines, we support aggressive production cycles with total yield stability. Our enterprise-grade MES (Manufacturing Execution System) delivers full-process serialization and traceability, allowing global clients to track any component down to its raw silicon source code batch, ensuring strict reliability for tier-one OEM contracts.
Customizing energy storage management to address localized grid configurations, environmental stressors, and variable utilities.
In regions plagued by extreme weather and utility strain (such as Texas or California), our high-capacity BMS works seamlessly with regional smart meters. By scheduling discharges during peak hours, homeowners bypass steep Time-of-Use (ToU) tariffs while securing high-reliability backup power for critical cooling and medical systems.
Under strict grid-feed regulations in Western Europe, the LTWSmart Micro Inverter operates alongside our intelligent BMS to maintain near-zero export balances. Excess daytime generation is directed strictly to local storage instead of backfeeding the grid, optimizing solar utilization and securing long-term economic independence.
From rural Australia to sub-Saharan microgrids, solar battery banks must endure harsh, dusty, and hot conditions. Our multi-series lithium protection boards, complete with active cell balancing and multi-sensor thermal throttling, guarantee continuous operational stability for vital irrigation and crop refrigeration systems.
For high-density municipal structures, our compact BMS allows space-saving energy configurations. Interfacing with virtual power plants (VPPs) via secure cloud networks, local battery stacks participate in ancillary services, generating monthly revenue while stabilizing localized distribution transformers.
Positioning our platforms at the forefront of solid-state, sodium-ion, and cloud-intelligent power storage systems.
With raw lithium subject to supply chain shocks, sodium-ion cells are emerging as highly viable alternatives. Litongwei has engineered a dedicated BMS architecture optimized for the unique voltage curves and thermal attributes of sodium-ion chemistries, ensuring reliable operation at temperatures as low as -30°C.
Integrating machine learning logic into cloud-connected BMS platforms allows our systems to cross-reference localized usage profiles with internal cell metrics. By identifying micro-short circuits or minor cell degradation anomalies early, it helps prevent thermal incidents and optimizes asset lifespans.
Our upcoming product lines support unified V2H communication interfaces, turning domestic electric vehicles into active home backup power sources. This modular approach allows users to use their EV battery capacity to power home loads during multi-day grid outages.
