Intelligent Series-Parallel Architecture Based on Cluster-Level Optimization | Exploring TAICO Energy Storage Solutions
1. The Essence of Series and Parallel Technology and Its Integration with TAICO Design
1. Series connection creates high-voltage core scenarios
Technical Principle: Series connection of batteries (positive to negative) increases system voltage. For example, 16 LiFePO4 battery cells at 3.2V each in series achieve the standard household voltage of 51.2V
TAICO Solution:
The HES series home energy storage battery supports flexible configurations of 15S (48V) or 16S (51.2V), compatible with various inverter input ranges (40-58.4V)
The industrial-grade high-voltage system supports multi-module series connection up to 204.8V, meeting the requirements of large-scale energy storage power stations and reducing transmission losses
2. Parallel expansion capacity and continuous power supply capability
3. Technical principle: Connect terminals of the same polarity (positive+positive, negative+negative) in parallel, with the voltage remaining constant but the capacity added up. For example, four sets of 100Ah batteries are connected in parallel to form a 400Ah system
TAICO scheme:
The T-ESS series supports 63 modules in parallel and can be expanded to 315kWh per system, making it suitable for community microgrids or backup power sources in data centers.
Patent current sharing technology solves the problem of parallel circulating current, with a capacity utilization rate of over 98% for each module
2、 Application of Series Parallel Combination: Engineering Practice of High Energy Density Systems
Case: Construction of 24V/400Ah Industrial and Commercial Energy Storage System
1. Series layer: 4 sets of 12V 100Ah TAICO T-ESS batteries → series connected to 48V 100Ah
2. Parallel layer: 4 sets of 48V 100Ah modules → parallel output 48V 400Ah (19.2kWh)
Advantage:
Voltage adaptability: compatible with mainstream 50kW three-phase inverters
Capacity elasticity: Supports batch expansion, mixed use of new and old batteries (requires BMS active balancing)
3、 Intelligent string architecture: TAICO's core breakthrough
Compared to traditional centralized solutions, TAICO adopts cluster level optimization design to achieve energy efficiency leaps:
| Dimension | Traditional centralized | TAICO intelligent string type |
| Energy efficiency | The barrel effect is significant, with a usable capacity of ≤ 85% | Cluster independent DC/DC optimization, capacity release ≥ 95% safety |
| Safety | Overcharge risk caused by circulation | Each cluster has independent temperature/voltage monitoring and automatic fault isolation |
| Operational costs | Single cluster fault requires shutdown for maintenance | Modular replacement, supporting hot swapping |
| Life cycle | The shortest battery cell determines the system’s lifespan | The difference in the number of cycles between clusters is ≤ 50 times, and the lifespan is extended by 10% |
ComTechnical implementation:
Each battery cluster integrates an intelligent power optimizer (IPO module) to adjust voltage consistency in real-time
Dual liquid cooling technology ensures that the temperature difference within the cluster is ≤ 2 ℃, delaying the decay of the battery cells
4. Key Security Strategies and TAICO's Engineering Protection
1. BMS quadruple protection system
2. Active balancing: Eliminating SOC differences in series connected cells (accuracy ± 1mV)
Parallel circulating current suppression: dynamically adjusting inter cluster current distribution
3. Safety design specifications
4. Hardware level: ceramic diaphragm cell (temperature resistance>150 ℃)+fuse protector
System level: Short circuit response<10ms, compliant with UL1973/IEC62619 certification
5.Typical application scenarios and TAICO solution selection
| Scene | Voltage demand | Capacity requirements | TAICO Recommended Solution |
| Home photovoltaic energy storage | 48-51.2V | 10-30kWh | TKS single cabinet (5.12kWh/module) |
| Convenience store off grid power supply | 96V | 50-100kWh | TK-ESS parallel cabinet x 4 (25kWh/cabinet) |
| Factory peak valley arbitrage | 384V | 500kWh+ | TK E-CUBE High Voltage System |
