Today, the concept of green energy, energy conservation and emission reduction is deeply rooted in people’s mind. The technological transformation of automobile energy power system has become the focus and core of automobile technology development. As an important part of new energy strategy and smart grid, electric vehicles will definitely occupy an important position in the future automobile industry development.
In practical use, for the purpose of safety, each DC charging gun is equipped with an electric lock (also called electronic lock) to prevent electric vehicles from having live guns drawn while charging. The gear motor for charging station electric lock is a kind of small power micro drive motor, whose main transmission structure is a piece of decelerating transmission equipment assembled by the integrated manufacturing of a driving motor (micro motor) and planetary gearhead (reducer). The driving motor can develop by adopting brush DC motor, BLDC motor, stepper motor, coreless motor and servo motor while the planetary gearhead can adopt satellite gearhead, cylindrical gearhead and worm gearhead as the reducer. The technical parameters of charging station electric lock drive are often customized for development including the output power, voltage, gear ratio, torque, transmission precision, transmission noise, etc.
ZHAOWEI Machinery & Electronics Co., Ltd provides the customized development service of gear motor for charging station electric lock. The customized technical parameters provided by ZHAOWEI are shown below:
Diameter: 3.4mm-38 mm
Voltage: below 24V
Output power: below 50 W
Output speed: 5rpm-1500 rpm
Speed ratio: 2-2000
Output torque: 1.0 gf.cm -50kgf.cm
Custom Development Service Case:
Project background: If the new-energy vehicle is equipped with the electric lock, the fee will be recorded once the electric lock locks, preventing the situation that the charging connection fails, but the fee continues to be recorded. After locking, it is unnecessary to manually support the charging gun and the electric lock can be regarded as the contact to record the fee. Once the electric lock is unlocked, the fee will stop to be recorded and the power will be disconnected. Also, the disconnection of the electronic lock with precise induction for vehicle systems means the completion of charging, avoiding an electric shock. It contributes to the unattended automatic charging operation after swiping the card while professional personnel is not required.
Solution: ZHAOWEI gear motor scheme for the charging station has passed the test of insertion and pull-out force of the plug-socket connector and presents to be suitable for the locking device between the plug and socket of the new-energy charging vehicles. In order to adapt to the compatibility with various charging stations and new energy technology, ZHAOWEI produces different specifications of gear motors (diameter: 3.4mm-45mm; voltage: 1.5V-36V). Moreover, the gear motor scheme can be customized for development according to the needs of charging station manufacturers.
