Advantages

1. Liquid Cooling

Unlike air-cooled battery cabinets, EnerOne+ uses a liquid cooling system that keeps cell temperature differences very small, improving:

• Battery life
• Capacity retention
• Safety
• Charging/discharging efficiency

The original EnerOne maintained cell temperature differences within about 3°C, contributing to its long service life.

2. CATL CTP (Cell-to-Pack)

CATL’s Cell-to-Pack technology removes unnecessary module structures, resulting in:

• Higher energy density
• Fewer electrical connections
• Lower failure rates
• Reduced weight

3. High Safety

EnerOne+ includes multiple protection layers:

• Cell monitoring
• Module monitoring
• Rack-level BMS
• Cabinet-level BMS
• Thermal runaway detection
• Aerosol/fire suppression
• Pressure relief vents
• Electrical isolation
• Fault diagnostics

CATL also incorporates its No Propagation (NP) technology to reduce the risk of thermal runaway spreading between cells.

4. Long Lifetime

Typical performance :

• Up to 10,000 charge/discharge cycles
• Around 20 years design life

For one full cycle per day :

• 365 cycles/year
• 10,000 cycles ≈ 27 years (actual service life depends on temperature, depth of discharge, and operating profile).

5. Flexible Integration

The cabinet is compatible with DC systems from 600 V to 1500 V, allowing integration with many third-party PCS brands, such as:
Sungrow, Sinexcel, Kehua, SMA, Power Electronics, Gamesa Electric, Delta ABB
This flexibility enables system integrators to optimize cost and performance.

6. Applications
