Detailed description

La MASTERVOLT MLI Ultra Liti 24/1250 és una bateria de liti-ion (LiFePO₄) robusta de 24V amb una capacitat nominal de 50Ah i una energia de 1250 Wh. Dissenyada per a entorns marins exigents, ofereix un rendiment fiable fins i tot davant corrents de càrrega/descàrrega elevats, humitat, xocs mecànics i vibracions. Aquesta bateria es posiciona com una solució energètica d'alta gamma, superant les bateries tradicionals en durabilitat amb més de 3500 cicles de vida al 80% DoD i un estalvi de pes i espai de fins al 70% respecte a les bateries de plom-àcid. Forma part de la sèrie MLI Ultra, reconeguda per les seves prestacions extremes i fiabilitat.

Tecnologia i gestió avançada

Al cor de la MLI Ultra 24/1250 hi ha un sistema de gestió de bateria (BMS) propietari i sofisticat. Aquest BMS assegura una utilització òptima de cada cel·la LiFePO₄, integra un algoritme d'autoequilibratge proactiu per a cicles de càrrega més ràpids i efectius, i ofereix una monitorització precisa de paràmetres clau com la tensió, el corrent, l'estat de càrrega (SoC) i el temps restant. Per a una seguretat addicional, un tallabateria integrat desconnecta les cel·les en cas d'anomalies (sobretensió, sotatensió, sobreescalfament, SoC baix), mantenint una capacitat de descàrrega contínua fins a 100 A (2C) i un corrent de pic de 250 A durant 10 segons.

Prestacions optimitzades en fred

Un avantatge destacat de la MLI Ultra 24/1250 és el seu sistema de calefacció tèrmica integrat, controlat pel BMS per optimitzar la càrrega a temperatures de congelació. Quan la temperatura de les cel·les baixa de 0°C, el sistema utilitza l'energia del carregador connectat per escalfar la bateria fins a 5°C, assegurant així una càrrega ràpida i capacitats de potència total fins i tot en condicions hivernals. Aquesta funcionalitat la diferencia de les bateries de liti estàndard, que poden veure reduïdes o bloquejades les seves prestacions de càrrega per efecte del fred, un avantatge competitiu notable respecte a solucions menys integrades.

Integració i flexibilitat

La connectivitat és un punt fort de la MLI Ultra 24/1250, integrant les comunicacions NMEA2000, CZone i MasterBus. Això permet una integració completa al sistema elèctric de l'embarcació i una configuració plug-and-play amb els carregadors Mastervolt compatibles, simplificant la instal·lació sense necessitat d'eines de configuració addicionals. Es pot configurar en sèrie fins a 48V i ofereix terminals de bateria M8 robustos, així com diverses opcions de muntatge (brides de fixació, manteniment lateral per grup 31/49). El seu índex de protecció IP65 garanteix una estanquitat total, essencial per a l'entorn marí, i està certificada UN 38.3, CE, E-Mark, FCC, UL1973 i RVIA.

« Technical analysis of the MASTERVOLT MLI Ultra 24/1250 battery »

The MASTERVOLT MLI Ultra 24/1250 battery represents a strategic energy solution for demanding marine applications. Its Lithium Iron Phosphate (LiFePO4) technology provides superior thermal stability and intrinsic safety compared to other lithium chemistries, a critical factor in embedded environments. The integration of a proprietary battery management system (BMS) is fundamental; it not only protects against overvoltage or deep discharge but also includes a predictive self-balancing algorithm that optimizes cell lifespan and charge cycle efficiency, a significant technical advantage for long-term reliability.

A distinctive feature of this MLI Ultra is its built-in thermal heating pad. This functionality is crucial for cold-water operations, ensuring the battery can accept optimal charging even when ambient temperature drops below freezing, preventing premature degradation of the lithium cells. Integration via MasterBus, CZone, and NMEA2000 greatly simplifies supervision and configuration within a Mastervolt electronic ecosystem or other compatible marine systems, streamlining installation and maintenance. Its IP65 design and resistance to shocks and vibrations make it a reliable choice for the harshest marine conditions, offering a high-performance and durable alternative to traditional lead-acid batteries.
