The POINTGUARD system also stands out by prioritizing battery safety through a five-layer protection system. This includes advanced temperature sensors, an internal fire extinguisher, aerogel insulating pads, pressure relief valves, and high-temperature-resistant cushions. This proactive approach ensures safe risk management from the outset, making the system truly unique on the market.
✅ Cell-level temperature monitoring (8x sensors per pack).
✅ Aerogel insulated pads, preventing thermal-runway
✅ Internal fire extinguisher.
✅ Decompression valve to avoid explosion of the enclosure in case of damage.
A well-designed BMS plays a central role in system protection. It typically halts charging or discharging in response to unsafe conditions like high/low temperatures or voltages. In a closed-loop setup, once the condition resolves, the BMS can also automatically resume operation—without user intervention.
Take cold-weather charging, for instance: lithium batteries are particularly vulnerable below freezing. A BMS will stop charging below 0 °C and only allow it to resume once the temperature returns to a safe level. Some advanced batteries incorporate internal heating or strict low-temperature logic to ensure optimal operation in colder climates.
Closed-loop systems also greatly reduce the burden of manual configuration. The BMS communicates charging parameters directly to compatible inverter-chargers using standardized communication protocols—often via robust and reliable CAN bus over CAT5 or similar cabling.
However, because signal wiring (e.g., CAN High, CAN Low, Ground) varies between brands, correct wiring and cable preparation are essential. Installers must refer to the inverter’s technical documentation and may need to set master-slave configurations when using multiple batteries in parallel.
A practical solution for these challenges is the LYNK II Communication Gateway, which bridges communication between Discover AES Rackmount battery batteries and supported inverter-chargers. It simplifies integration by eliminating the need for crossover cables and automatically managing battery network communications.
Some systems go further by enabling dynamic charging, where the BMS continuously sends optimal, real-time voltage and current targets. This approach shortens charging time and minimizes energy losses from cable resistance.
Dynamic systems also excel at cell balancing—a process that evens out charge across all cells in the battery. The BMS slightly raises voltage at the end of the charge cycle while reducing current, allowing higher-voltage cells to finish charging safely.
