What is the NIO battery heating for?

New energy vehicle battery preheating is to keep the battery at a normal operating temperature. The main functions of new energy electric vehicle battery thermal management include: precise measurement and monitoring of battery temperature; efficient heat dissipation of the battery under high temperature conditions; Battery cooling system and matching other cooling units.

Friends who drive fuel vehicles all know that there will be a process of warming up the vehicle during winter use. Although with continued advancements in technology, it is now rare to warm up the vehicle while idling. but in the past For two or three kilometers, try to keep a constant speed and do not drive violently. This will extend the life of the engine. The same goes for vehicles.today's purely electric vehicles: the battery must be preheated.

As the temperature is low in winter, the battery life of electric vehicles is generally significantly reduced. This is mainly because the viscosity of the battery electrolyte increases under low temperature conditions. The electrolyte plays a role in the conduction of ions between the positive and negative electrodes of lithium batteries, and is also the guarantee for lithium ion batteries to obtain the advantages of high voltage and high specific energy . Therefore, an increase in electrolyte viscosity will lead to a decrease in battery charging and discharging performance.

At this time, the battery is preheated, which can effectively alleviate this situation. For battery preheating, each manufacturer has different technologies. Some install radiators around the battery, while others heat the battery coolant to keep it at a normal operating temperature. It should be noted that although there are preheating measures under extremely low temperature conditions, charging and discharging will also cause certain damage to the power battery.

However, car owners have no clear obligation to heat their car while in use. However, in order to ensure cruising range, when driving in low temperature conditions, try to develop good driving habits and avoid violent driving when pressing the switch. Because it will not only reduce the cruising range, but also cause damage due to rapid discharge of the power battery, thereby shortening the life of the power battery. When the time comes toe replace the battery, the gain exceeds the loss.

Defu electric heating products include: heated belts, heated clothing, heated insoles, heated gloves, heated scarves, USB heated sheets, heated fabrics electric, personalized heated fabrics, heated sheets for vests. , carbon fiber heating fabric, graphene heating fabric, electric blanket heating fabric, carbon fiber heating sheet, silicone heating sheet, PI heating film, PET heating film, graphene battery, graphene floor heating, etc. .

Heating is not recommended. I am from the north and will encounter the situation you mentioned. This will cause unnecessary difficulty to the car's radiator. Generally speaking, this is not beneficial. car The model also corresponds to several heating solutions for vehicleses pure electric using different methods of fuel heating, electric heating and heat pump heating, and a comparative analysis of several solutions is conducted. I hope I can help you
