Core competence
The reliability of the 5-in-1 pure electric drive assembly is strong
The functions of motor control, DC/DC, DC/AC, vehicle-mounted charging and high voltage distribution are integrated together. It has the advantages of high integration, overall layout, easy maintenance, high level of the protection of the vehicle, and good cooling effect, etc.
Battery safety
The battery has passed through many destructive experiments, such as high temperature, short circuit, extrusion, soaking, overfilling and puncture.
Quality assurance
The period of the quality assurance is 5 years, which can be extended to 8 years. The single vehicle has completed the tests of 30,000km comprehensive road test and battery high-temperature loop test and the battery capacity is reduced by 10%. The battery reaches the capacity level of not less than 75% after 5000 times of charging and discharging, which means the service life of the vehicle can reach 8 years and solve your worries about the battery.
Intelligent remote control which improves the driving safety of the vehicle
The running state of the vehicle, the voltage and temperature of the battery, the precise location of the vehicles and such information are monitored in real-time, so as to ensure the optimum battery status, the security of the operation of the vehicle system, at the same time assist the urban public transportation system to complete the traffic scheduling. Functions such as custom ruling alarm, expert-level diagnosis are also owned.

  • 02
    Stations constructed by the customers
    Nanjing Jinlong has developed a professional charging infrastructure design scheme based on the needs of the customers, which can assist customers to complete the construction of charging supporting facilities.
  • 03
    Stations constructed by the third party
    Nanjing Jinlong provides candidate resources of third-party: The charging technicians of Jinlong assist customers to make butt joints and debug the charging technologies.
  • The advantages of the charging stations
    The capital investment in the early stage is small. It only needs to match the corresponding charging piles according to the number of vehicles. The requirements on the charging site are not high. The existing site can be used to construct the charging stations.
  • The disadvantages of the charging stations
    The capital investment in the early stage is small. It only needs to match the corresponding charging piles according to the number of vehicles. The requirements on the charging site are not high. The existing site can be used to construct the charging stations.
  • The advantages of the substations
    The floor space is small and the discharging time is quick. Self-purchasing model: The corresponding numbers of the batteries are matched according to the numbers of the vehicles. The rights of the use, management and ownership of the battery will be returned to the owner. The cost of the batteries will be generated. Battery leasing mode: The batteries are provided by the State Grid Corporation of China and the manufacturers of the batteries. The leasing way is adopted when using batteries. The management and ownership of batteries belong to the State Grid Corporation of China and the manufacturers of the batteries, which can greatly reduce the purchase cost of the batteries.
