Maintaining the State of Charge (SOC) balance in battery packs is crucial for the performance and longevity of golf cart batteries. Olelon’s Magic Series modular batteries are designed with advanced technologies to ensure each battery module’s SOC remains consistent. Here are the key measures and mechanisms Olelon employs to achieve SOC balance and optimal battery performance.
1. Role of Independent BMS
Each module in the Magic Series is equipped with an independent Battery Management System (BMS). This system monitors and manages the voltage, current, and temperature of each battery module, ensuring they all operate in optimal conditions. The independent BMS plays a critical role in maintaining SOC balance across the battery pack.
2. Overall Monitoring with Smart Box
After connecting the battery modules through physical wiring (both parallel and series connections), they are integrated into a smart box. This smart box provides comprehensive monitoring of all battery modules, offering advanced management and control functions. It ensures the safety and performance of the entire battery pack by constantly monitoring the SOC, health status, and temperature of each module.
3. Balancing Features of the Smart Box
- Active Balancer: The smart box features an active balancer, which transfers charge between modules to maintain consistent SOC levels.
- Passive Battery Equalizer: It also utilizes a passive battery equalizer, which dissipates energy from modules with higher SOC to balance the entire battery pack’s SOC.
4. Bluetooth Connectivity and APP Monitoring
- Bluetooth Module: The smart box connects to an APP via a Bluetooth module, allowing users to monitor the real-time and historical data of the battery pack and individual modules.
- Real-Time Data Monitoring: The APP provides real-time data on voltage, current, temperature, and SOC, helping users detect and address inconsistencies promptly.
5. Regular Maintenance and Inspection
- Periodic Inspections: Regular inspections using the APP and smart box help identify and resolve potential issues early.
- Equalization Charging: Periodic equalization charging ensures all battery modules are fully charged, preventing SOC discrepancies.
6. Temperature Management
- Uniform Temperature Control: The smart box and independent BMS monitor and manage the temperature of each battery module, ensuring consistent operating conditions and preventing performance variations due to temperature differences.
7. Preventing Over-Discharge and Over-Charge
- Over-Discharge Protection: The BMS provides over-discharge protection, preventing individual modules from discharging too much and causing SOC imbalance.
- Over-Charge Protection: The BMS also offers over-charge protection, ensuring no module is overcharged, which helps maintain SOC balance.
8. Data Analysis and Predictive Maintenance
- Data Analysis: The APP and smart box analyze historical data to predict and preempt SOC imbalance issues.
- Predictive Maintenance: Based on data analysis, predictive maintenance can be performed to replace or repair modules with declining performance proactively.
By implementing these advanced technologies and management strategies, Olelon’s Magic Series batteries ensure each battery module’s SOC remains balanced. The combination of independent BMS, smart box monitoring, active balancers, and passive battery equalizers provides a highly efficient and safe user experience. This meticulous approach to SOC management enhances the performance and lifespan of the batteries, making them ideal for golf cart applications and beyond.
