Automobiles consume about 40% of the world’s total oil production. Energy shortage (oil) and environmental protection have triggered the upsurge and direction of electric vehicle development and manufacturing.

What influences consumers’ decision-making and experience of purchasing electric vehicles?

The new infrastructure project after the epidemic is to solve the problem of electric vehicle charging, and the operation efficiency of electric vehicle drive system. The vehicle power battery is the power source of the vehicle, the battery power into the efficiency of the drive motor directly affects the range of electric vehicles, is particularly concerned!

Relevant test standards:

GB / T 29307-2012 reliability test method for driving motor system of electric vehicle

GB / T 18488.1-2015 electric vehicle drive motor system Part 1: technical conditions

GB / T 18488.2-2015 drive motor systems for electric vehicles Part 2: Test methods

The electric vehicle wireless charging technology is to transmit the electric energy to the vehicle receiving end electric energy pickup mechanism in the form of high-frequency alternating magnetic field through the power supply rail buried under the ground, and then supply power to the on-board energy storage equipment. It can make the electric vehicle carry a small amount of battery pack, achieve the effect of reducing weight and extending its driving range, and at the same time, the electric energy supply becomes more safe Convenient.
