Vertec Introduction

"FAW VERTEC" is 100% electric-supplied and "quiet enough, steady enough, enough power". It is different from diesel or hybrid trucks. Since pure electric trucks do not emit air pollutants caused by the burning of fossil fuels during its runnin, it is unnecessary to install exhaust hoses on trucks. VERTEC has zero roadside emissions, which are the real solution to curb roadside air pollution. The noise generated by the electric motor is lower than the engine, which greatly reduces the road noise problem. The residents is no longer affected by directly roadside exhaust and noise while going through the neighborhood, thereby, they possess fresher and quieter environment.

Introduction

We use lead-acid battery which is suitable for electric bicycles, electric trucks and special purpose electric vehicles mainly.

Our product  has passed ISO9001:2008 quality control system, ISO14001:2004 environmental management system, GB/T28001-2001 occupational health and safety management system certification, CE certification

Security

- 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
