AI Technical Summary

Technical Problem

The existing new energy vehicle charging system is difficult to effectively control the battery temperature during fast charging, resulting in long charging time, large energy loss and high cost.

Method used

Design a new energy vehicle charging pile with thermal management components, including a built-in cooler, water pump, heater, liquid storage pot, as well as external outlet pipes and return pipes. Through electrical signal communication, the cooling or heating system will be automatically started to maintain the battery temperature within the appropriate range.

Benefits of technology

It realizes that without increasing vehicle costs, ensuring that the vehicle power is not lost during fast charging (2C ratio), reducing the cost of the entire vehicle, and improving the charging experience.

Abstract

The invention discloses a new energy automobile charging pile with a heat management assembly, which is mainly characterized in that the heat management assembly is composed of a cooler, a water pump, a heater and a liquid storage pot which are arranged in the charging pile, and a water outlet pipe and a water return pipe which are arranged outside the charging pile, the liquid storage pot is connected with the water return pipe through an internal pipeline; the cooler and the heater are respectively connected to the internal pipeline; a battery management system of the to-be-charged automobile is in electric signal communication with a control system of the charging pile, and after it is detected that a charging gun is in place, the battery management system continuously detects the temperature of a vehicle-mounted power battery; when it is detected that the temperature does not reach the standard, the battery management system correspondingly sends a cooling or heating instruction to the charging pile to start the water pump and the cooler or the heater to work, so that on the premise that the new energy vehicle does not need to be provided with the battery thermal management system, large charging multiplying power is ensured, good charging experience is brought to a user, and the charging efficiency is improved. And the cost of the whole vehicle is also obviously reduced.
