Key benefits - Improves long term pack health: as battery cycle life increases, cell capacity decline can occur irregularly and cause voltage imbalance. This balancing module actively maintains even cell voltages to reduce imbalance and preserve overall pack performance. - Flexible balancing current from 0 to 5.5 A: supports different pack conditions and balancing needs. When the voltage difference between cells is 0.1 V, the balance current is 1.0 A. The current is proportional to the voltage difference, and as cells become more balanced, the balancing current naturally decreases. - Precise voltage compensation: compensation voltage accuracy is within 5 mV, enabling careful and reliable balancing across cells. - Very low idle drain: operating current in idle mode is less than 0.1 mA, minimizing standby power loss in idle equipment or systems. - Ready for sleep switch integration: space is reserved for a sleep switch, simplifying incorporation into larger power management solutions. - Clear function and performance: designed to balance multi cell packs efficiently with predictable current behavior and high-precision voltage control, aiding compatibility with a variety of battery configurations. How it works - Balancing action is driven by cell voltage differences. The device delivers current to the cells with lower voltage to bring them in line with higher voltage cells. - The balancing current scales with the imbalance: larger voltage gaps draw more current, while small gaps reduce current as balance is achieved. - The system maintains tight voltage control with a compensation accuracy of up to 5 mV, ensuring stable and accurate balancing outcomes. - When not actively balancing, the module draws minimal power (less than 0.1 mA) to minimize waste and prolong system life. - The design provides reserved space for a sleep switch, enabling easy power management within integrated systems. Specifications at a glance - Balancing current range: 0 A to 5.5 A - Voltage difference to current relationship: 0.1 V difference corresponds to 1.0 A balancing current - Voltage compensation accuracy: within 5 mV - Idle current: less than 0.1 mA - Sleep switch integration: space reserved Compatible use scenarios - Multi cell packs in electric vehicles, power tools, and portable devices: maintain even cell voltages across the pack to extend cycle life and reliability. - Home and mobile energy storage: support balanced operation in solar or UPS style battery systems that use stacked cells. - RC hobby and portable power solutions: keep pack voltages aligned during frequent charging and discharging cycles, improving performance and longevity. Usage considerations - Best applied to packs that require active cell balancing to prevent voltage drift and capacity loss across cells. - Suitable for configurations where a sleep switch can be integrated or where space is allocated for future power management features. - Pairing with a compatible battery management system (BMS) or controller enhances overall pack safety and performance. Notes - The described features focus on balancing function, current behavior, precision, low idle consumption, and integration space for a sleep switch. - No adjustments to core pack chemistry or materials are implied; the module targets balancing performance and efficiency within existing battery configurations.
