겨울에 전기 자동차 배터리 수명이 급격히 떨어지면 어떻게 해야 하나요? Posted by batterymanufactory.com
Winter is here, and many electric car owners have found that the range displayed when fully charged is "halved", the charging speed is slowed down, and even the power output is weakened. Some people say that "electric cars are naturally afraid of cold", while others question that "there are problems with the battery quality". What is the truth? This article will analyze the impact of low temperature on electric car batteries based on the chemical properties of lithium batteries, and provide a full range of solutions from charging skills to driving habits to help you say goodbye to winter range anxiety. I. Are electric car batteries really "afraid of cold"? 1. The essence of low temperature effects: reduced activity, non-permanent damage When lithium batteries are at low temperatures (especially below 0°C), the viscosity of the electrolyte increases, and the migration speed of lithium ions between the positive and negative electr...
