High cell-count applications present unique battery management and thermal management challenges Battery pack design is a complex, multi-step process with many decisions. After cell chemistry, perhaps the two most important decisions in battery pack design are the number of cells and the arrangement of the cells. Chemistry determines, among many other properties, the nominal voltage of a cell. The size of the cell in turn determines the capacity. To double battery capacity, put two cells in parallel. To double battery voltage, put two cells in series. Pick the proper arrangement to meet … [Read more...]

A BMS collects data, calculates vital statistics, and controls battery function All batteries work safely and effectively within certain optimum conditions. Using them outside these conditions can shorten productive life and create hazards. For instance, overcharging a battery may both reduce its capacity long-term and be dangerous to users. However, the outside appearance of a battery tells you very little about its condition, making it difficult to monitor the battery’s health. A battery management system (BMS) solves this problem by monitoring battery vital signs and ensuring safe and … [Read more...]

Battery chemical reactions are at the heart of battery design Well-designed batteries power your equipment efficiently, reliably, and safely for a long lifespan. To achieve this combination of ideals, engineers evaluate certain design parameters, including voltage and power needs, length of duty cycle, temperature conditions, price, and more to guide their design choices. Battery chemistry is perhaps the most fundamental design choice. At their heart, all batteries are conveniently-packed electrochemical reactions. The ability of a battery to store and discharge electricity depends … [Read more...]

For battery safety and performance, invest in a battery thermal management system Battery thermal management allows batteries to safely and effectively provide power. At their heart, battery packs are conveniently-packaged electrochemical cells. When the battery is charged or discharged, a chemical reaction occurs. Like many chemical reactions, these reactions depend on temperature. Thermal management is all about maintaining batteries at temperatures that are safe and promote optimal battery performance. Custom battery packs are an investment. The application of good thermal management … [Read more...]
