The importance of battery management is self-evident. More and more products are portable direction, users obtain unprecedented independent. Several decades ago, cordless telephone first provides a stroll in the home of the free people. And now, portable rechargeable products so that people in the world at the same time, we can keep in touch with family. More and more medical equipment use rechargeable batteries, and with the product volume reduction, the complexity of these products are also constantly improving. Charging the battery itself is also changing, battery manufacturers to launch new products to adapt to the rapid changes in the market. The battery voltage increases, the shape size change, energy density is also rising in. Consumer understanding of the battery also unceasingly thorough, they need products with greater flexibility, longer working hours, lower cost and higher security. Shenzhen BRAVO Power Company Limited has been committed to the research and development of intelligent battery management, in order to simplify and better management of charging system. The BRAVO’S battery management are intelligent charge and discharge management system power of independent research and development of lead-acid battery, lithium, nickel. Built-in the battery charging, battery activation normal charging, charging overvoltage alarm, battery charging current, the battery voltage alarm, battery under-voltage protection, reverse battery protection etc function.
1.Charging management
Battery two cell based on different from a battery, two battery needs recharging after use, and not like a battery that can be discarded. Charging circuit and charging algorithms are various, for a particular chemical battery types, unique in its system environment for its proper charging. battery in the medical device package is not removable. Charging method of lead-acid batteries, lithium batteries and nickel-metal hydride battery is constant-voltage-restricted-current method, but the battery to determine whether the way charge varies greatly. The characteristics of various battery research, state of the battery management solutions for battery accurately monitoring, including the charging time, charging voltage, charging current, temperature range, so that the state of the battery is best, to meet customer demand.
2. The discharge management
Discharge management is the two battery is another important index, any kind of batteries, over discharge may cause a decline of battery performance, life is reduced, or even damage the battery, therefore, the battery is fully discharged when the need to shut down the system in a timely manner, so as to avoid excessive discharge of the battery. Because of the built-in MCU, discharge we monitor the battery in the battery state, nearly exhausted, under-voltage warning given batteries, if the battery voltage reaches the end of discharge voltage stop discharge.
3 Protection
When using lithium / polymer batteries, must provide protection function, because the overcharge or overheating may cause fire or explosion. Lead-acid battery or nickel batteries without protection, but also often provide protection circuit to prevent cell damage or degradation. The main protection circuit is a special circuit, is used to detect whether there is insecurity, insecurity and to close the battery to avoid damage in detection. Two protection circuit prevents the battery in unsafe conditions continue to charge and / or discharge. In case of failure of main protection circuit, the two circuits can be reset to provide back-up protection. The intelligent charge and discharge management system Bai Rui arcane power can monitor the battery voltage, current and temperature.
