Security

－ Ternary battery to comply with the national standard test；
－ The battery pack meets  the requirements of GB/T 18384-2015 for personnel protection against electric shock, the UL 94-VO flame retardant requirements and the ECE R100 fuel burn exposure for 60 seconds.
－ The battery management system combines active safety protection with passive protection to ensure that safety measures and fault protection can be taken in case of danger.
－ Battery management system (over voltage, under voltage, over temperature, over current, etc.) functional safety design level meets ASIL C, conforms to ISO26262 standard, and is approved by Germany TUV South German security evaluation.

Long mileage range

High-energy-density core and lightweight structure design effectively increase vehicle running mileage.
－ Ternary composite NCM battery module, energy density is up to 165Wh/kg
－ PACK Level Energy Density, NCM Box > 110Wh/kg

Long-period

It remains 80% of cells capacity after 1500 cycles or 5-year use.

Good environmental adaptability

 Protection
－ The battery pack adapts to harsh weather conditions and the enclosure seals to IP67
－ Gravel impact, thermal load test, and fireproof design guarantee the reliability of the product  effectively
－ The metal box and main external structural parts are all electrophoresed using KTL. The product passes the SGS standard 720h salt spray test to ensure that the anti-corrosion ability meets the service life of the product for more than 8 years.
－ Battery system failure rate, easier to maintain and maximize product benefits

Battery Management System (BMS)

  1. Detection
    Measure the battery voltages, current, various area temperatures of the pack in real time, and calculate State of Charge accurately.
  2. Balance Function
    Highly efficient function in dynamic & static balance function can guarantee the favorable uniformity of battery.
  3. Alerting Function
    BMS provides alerts of charging warning, high temperature, insulation, cell wire falling, battery fault, etc..
  4. Transmission
    Uploads raw data on drives. Uploaded data will be analyzed and saved. Provides advance warning to truck’s owner before malfunction.

Technical Hightlights
