The safety of electric vehicles

In 2014, “The National and Local Joint Engineering Research Center” settled in Nanjing Jinlong

The national level research and development platform “The National and Local Joint Engineering Research Center” is located in Nanjing, which is committed to building the world-leading new energy vehicles which have the features of safety, reliability, economy and environmental protection. The vehicle has passed through more than 20 items of rigorous tests, including vehicle, battery, motor, electric control and so on. It also has the guarantee on the terms of driving safety.
The safety diagram of the body structure of the vehicle

The vehicle adopts the modular arrangement structure and lightweight high steel plate hot forming technology and other technologies. Combined with CAD/CAE/CAM analysis, constraint system simulation analysis, virtual simulation and the combination of calculation and test, it tries to construct the integrated design platform and the method of the body and chassis of the vehicle, so as to realize the integration of the constructions such as the structure optimization design of the vehicle, static and dynamic performance. The design and production of the lightweight structure of the vehicle are carried out, which effectively reduce the energy consumption of the vehicle.
Protective safety

The level of the production reaches IP67, the wading depth is high; The measures of the passive safety are improved, the intelligent battery power system is installed. When the fire occurs, the battery compartment can quickly disengage and power off to prevent the disaster from deteriorating.

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.

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.
The disadvantages of the substations

Based on the characteristics of customer sites and operation, Nanjing Jinlong has developed a comprehensive charging infrastructure solutions for power distribution, charging, monitoring and infrastructure and organized the construction to provide turnkey engineering services.
