The battery must be operated within its specified temperature ranges to prevent thermal runaway or capacity degradation. Charging requires a compatible BMS with over-discharge, over-current, and cell balancing protection.
- Temperature Limits: Discharge operation is limited to -20°C to 65°C and charging to -10°C to 55°C to avoid electrolyte instability or damage.
- Preconditioning Requirement: New batteries must be preconditioned at room temperature before the first full charge cycle to stabilize the semi-solid electrolyte interface.
- Discharge Cut-off Protection: The BMS must enforce a discharge cut-off voltage of 36.4 V to prevent deep discharge and irreversible cell damage.
- Current Limitation: Continuous discharge current must not exceed 35 A to avoid overheating and internal resistance rise beyond the 9 mΩ specification.
Follow these steps to safely prepare the battery for first use and integrate it into an electric bicycle. Always use a compatible BMS and observe the specified voltage and temperature limits.
Required Equipment: Compatible battery management system (BMS) with over-discharge, over-current, and cell balancing, Charger capable of supplying the recommended voltage range
- Inspect the battery
Inspect the battery package for physical damage, deformation, or leakage before unpacking and handling. - Connect the BMS
Connect a compatible BMS with over-discharge, over-current, and cell balancing protection to the battery terminals. - Precondition at room temperature
Charge the battery within the recommended voltage range at room temperature (20–25°C) for the first full cycle to precondition the electrolyte. - Set discharge cut-off voltage
Verify the BMS discharge cut-off voltage is set to 36.4 V to prevent deep discharge and extend cycle life.
How does the 35A maximum continuous discharge (1C) affect hill-climbing performance and battery life on long commutes?
The 35A maximum continuous discharge (1C rate) supports consistent hill-climbing and acceleration. With 35Ah capacity and ≤9 mΩ internal resistance, the battery delivers high power output. The cycle life is ≥1000 cycles to 70% SOH under standard conditions; sustained operation at the 1C discharge rate may reduce cycle life but remains within specified limits.
Can this 48V 35Ah semi-solid battery be integrated with existing e-bike controllers and BMS systems?
Yes, but integration requires a compatible BMS with over-discharge, over-current, and cell balancing. The battery uses a 13S1P configuration with nominal voltage of 48V and discharge cut-off at 36.4V. The controller must accept 48V input and handle up to 35A continuous current. The battery is intended for electric bicycles, e-scooters, and light electric vehicles.
What are the specific temperature constraints for charging and discharging this semi-solid battery in cold climates?
The charge temperature range is -10°C to +55°C, and discharge range is -20°C to +65°C. Avoid prolonged exposure above 65°C. For initial use, pre-condition new batteries at room temperature before the first full cycle. The semi-solid electrolyte enhances thermal stability and leak-proof construction, improving safety in cold-weather operation.
The ATOMFAIR Rock Solid Series 48V 35Ah semi-solid state battery for electric bicycles offers enhanced safety through leak-proof semi-solid electrolyte and wide -20°C to +65°C discharge capability, but requires a compatible external BMS and careful temperature management during charging due to a narrower -10°C to +55°C charge temperature range.
Positive
- Semi-Solid Electrolyte Safety: Enhanced thermal stability and leak-proof construction provide superior safety over conventional liquid cells, validated by nail penetration and overcharge test passes.
- Wide Operating Temperature Range: Discharge from -20°C to +65°C enables reliable all-season e-bike operation, suitable for cold climates and hot environments.
Trade-offs
- Narrower Charge Temperature Range: Charging is limited to -10°C to +55°C, narrower than the discharge range, requiring temperature-controlled charging infrastructure to avoid operating outside specifications.
- Requires External BMS: Proper operation mandates a compatible battery management system with over-discharge, over-current, and cell balancing protection, adding integration complexity.
