Charging Specifications of the MEAN WELL NPB Series
Understanding the 2-stage and 3-stage charging profiles
How you charge is just as crucial as what you charge with. Ensuring that a battery is charged optimally is paramount for its longevity and efficiency.
This brings us to the intricate science of charging profiles. Among the most prevalent and effective profiles are the 2-stage and 3-stage charging methods, which come as presets on the NPB series battery chargers.
Let’s break these down to understand their mechanics, benefits, and ideal scenarios.
2-Stage Charging: A Simplified Approach
2-stage charging is primarily recommended for Li-ion batteries. It ensures a rapid yet safe charging process, making it ideal for devices and applications that demand quick energy replenishments.
- Stage 1: Constant Current: This is the initial phase of the 2-stage charging method. The battery is charged at a consistent and steady current. This helps in replenishing the major chunk of the battery's capacity.
- Stage 2: Constant Voltage: The charger transitions to the constant voltage phase once the battery has reached a certain voltage threshold during the constant current phase. The voltage remains stable while the current gradually tapers off until the battery is fully charged.
- Indicator Mechanism: The NPB series features a color-based LED loading indicator to make monitoring straightforward. An orange glow signifies the constant current stage, and once it shifts to green, the charger has moved to the constant voltage stage.
3-Stage Charging: Comprehensive Battery Care
3-stage charging is predominantly tailored for lead-acid batteries. The inclusion of the float voltage stage ensures these batteries are kept at optimal levels, especially when they're connected continuously, like in backup power systems.
- Stage 1: Constant Current: Similar to the 2-stage method, the 3-stage charging starts with a constant current phase. This rejuvenates the depleted battery, preparing it for the subsequent stages.
- Stage 2: Boost Voltage: The charger switches to a boost or “bulk” mode once the battery approaches its peak capacity. The voltage is elevated to ensure that the battery receives a full charge without overcharging.
- Stage 3: Float Voltage: The final phase involves maintaining the battery at its peak. The charger provides a floating voltage, ensuring the battery remains fully charged without overloading its cells. This stage is particularly crucial for batteries that remain connected for extended periods.
- Indicator Mechanism: The transition between stages is also indicated by LED color shifts in the 3-stage charging method. The sequence progresses from orange (constant current) to green (boost voltage) and finally to a sustained green glow during the float stage.
MEAN WELL NPB chargers come equipped with standard 2-stage and 3-stage charging settings, offering versatility for a wide range of charging applications, including those that use lead acid and lithium-ion batteries. While these settings are suitable for most scenarios, adjustments may be necessary based on battery configurations and types. In such cases, users can easily modify parameters or establish custom charging curves, particularly with the advanced capabilities of the higher power (>450 watts) NPB series. Read further to explore how these chargers facilitate tailored charging solutions.
Ability to set custom programmable charging curves
The NPB battery charging series ranging from 450 watts (NPB-450) to 1700 watts (NPB-1700), offers a versatile solution with a user-friendly programmable interface and integrated CANBus communication protocol. The integration of CANBus into these intelligent battery chargers give you the precise control over charging curve paramters such as constant current level, boost voltage, float voltage for specific battery types. This allows for advanced control by external Battery Management Systems (BMS). With its adaptable settings, the NPB series 450W to 1700W can effortlessly accommodate a diverse range of application needs, ensuring seamless integration and optimal performance.
What is CANBus and how is used in battery chargers?
The Control Area Network Bus (CANBus) is a standardized communication protocol enabling electronic control units to exchange data seamlessly. Known for its superior reliability compared to PMBus, CANBus boasts high immunity to electrical interference and self-diagnostic capabilities. Like PMBus, CANBus facilitates power supply control and monitoring. In charging applications, users can adjust parameters such as constant current level, boost voltage, and float voltage tailored to specific battery types. CANBus adheres to the CAN ISO-11898 standard with a baud rate of 250Kbps, utilizing the extended CAN 29-bit identifier frame format, or CAN 2.0B. In essence, MEAN WELL Intelligent battery chargers feature built-in CANBus communication protocols, empowering users to efficiently control, monitor, and configure chargers according to their precise battery electrical requirements.
Example of CANBus used to charge warehouse robots
In this application, a CANBus charger is utilized within the charging station. Upon the robots' return to the station, the system promptly detects the connection status of the port and employs CANBus technology to activate the charger. Furthermore, CANBus enables precise control over the charging voltage and current parameters, ensuring efficient and reliable charging for the robotic fleet.
