Tesla's official website said that Chinese consumers who purchased Model S, Model X, and Model 3 after January 15 used a super charging station to charge vehicles, and Tesla would charge 1.8 yuan per kWh. Charging fee. Vehicle buyers before this date are not affected by this policy.

Tesla announced charging standards for charging piles in China. Old car owners are not affected by the new policy.

New customers who purchase Tesla Motors after 15 days enjoy 400 kWh (equivalent to 1600 km) of free charging each year. Tesla's unified charge in China is 1.8 yuan per kWh, which is slightly more expensive than California and New York. Tesla said that this fee is for reference only and will be adjusted in the future.

In addition, Tesla will charge the owner 2.6 yuan per minute for charging overtime parking. The timing starts from 5 minutes after the vehicle is fully charged, in order to solve the problem that the owner uses the charging station as a parking lot and relieves the pressure of the charging station. Tesla will begin a similar policy in the global market, and in North America, the price of electricity in each state or province remains the same. In North America, prices are consistent across countries.

Piezoelectric Elements For Inkjet Piezo Transducer

Piezoelectric ceramic ring



Applications: ultrasonic vibration tranducer for inkjet printer



Vibration mechanism of inkjet printer:

Generally, it is composed of piezoelectric ceramics and driving rods. By high-frequency electric excitation, piezo ceramics produce high-frequency ultrasonic vibration (above 60 kHz or higher), which is transmitted to the driving rod and generates high-frequency micro-displacement (back and forth expansion) at its front end.

Piezo ceramics components features :

1. High vibration amplitude and can withstand higher power.
2. The product has high reliability, strong maintainability, and is not easy to break down or off-line.
3. The frequency can be adjusted in a wide range, generally within the range of 10KHz.
