With the popularity of NEVs, owners care more about battery life. As the core part, battery health affects range and longevity. This guide covers charging methods, pile choices, power, and habits to protect your battery.
I. Charging Methods: Scientific Charging for Longevity
1. Avoid Overcharge and Over-discharge
Overcharge: Keeping a battery full for long accelerates aging. It’s suggested to stop at 80%-90%.
Over-discharge: Avoid dropping below 20%, as low power causes irreversible damage.
2. Shallow Charge/Discharge, Periodic Full Charge
Shallow charge: Avoid fully exhausting before charging to reduce cycles.
Periodic full: At least once a month, a 100% charge helps balance the state.
3. Use Smart Equipment
Smart charging: Devices with scheduling systems automatically adjust current and voltage.
Timed charging: Use off-peak hours to save money and reduce grid impact.
II. Choosing the Right Pile
1. Compatibility
Ensure compatibility with your brand, model, and national standards (GB/T 20234) for stability and safety.
2. Pile Types
AC (Slow): Better for daily use and battery health. Ideal for home or work.
DC (Fast): For emergencies or long trips, as frequent use can hurt the battery.
3. Power Choice
Choose based on battery capacity. Home AC is usually 7-22kW, DC is 30-350kW. Suggestions: 7-11kW for daily slow, 60-120kW for fast.
III. Charging Power: Balancing Speed and Protection
1. Impact of High Power
Excessive power increases internal temperature, accelerating aging and reducing cycle life.
2. Choose HARDHITTER Smart Scheduling
HARDHITTER fast piles with smart scheduling allocate power based on battery state and temperature, ensuring safe and efficient processes.
IV. Daily Habits: Longevity for the Battery
1. Avoid Extreme Heat
Charging in heat accelerates aging. Use shady, ventilated areas.
2. Avoid Extreme Cold
Cold reduces efficiency and life. Use indoor or suitable temperature areas.
3. Periodic Checks
Get professional checks and update software to keep the BMS optimal.
4. Plan Trips
Plan based on range and charging spots to avoid frequent fast charging or over-discharging.
V. Other Tips: New Tech and Methods
1. Thermal Management
Choose vehicles with thermal management to control temperature.
2. Battery Balancing
Periodic balancing helps even out cell power for longer life. Everyone’s conditions differ, so arrange usage reasonably. Enjoy green travel while protecting your battery!
