Enfriamiento de la batería | Sistema de gestión térmica de la batería – TKT

Tecnología de enfriamiento de batería

It is also known as battery thermal management system (BTMS), or battery cooling system (BCS), or electric battery thermal management (eBTM), or battery cooling, or battery pack cooling system. The main purpose is to ensure that the battery pack can discharge power within the optimum temperature range. This ensures maximum stability and efficient power release. Actualmente, the technology in this area of small cars is relatively simple. But that's rare for larger vehicles like electric buses and electric trucks. This is because the battery pack of a larger vehicle generates more voltage and current during operation. This requires more expertise.

The Necessity of Battery Thermal Management System

The global climate continues to heat up, and the increasing severity of climate disasters in recent years illustrates the seriousness of the matter. Protecting the environment is becoming a growing concern around the world. Countries are inclined to start adopting electric buses and electric trucks.
The process of releasing power from a battery is inevitably accompanied by the release of heat. The optimal operating temperature for batteries is 20° to 40°, y if this temperature is exceeded, not only will the performance of the battery will be reduced, but the driving range and the life of the battery will be drastically reduced. More serious, it may also affect the surrounding equipment, causing the consequences of combustion and explosion. This is where battery cooling technology comes in.

Best Battery Cooling Technology - Refrigeración líquida

Traditionally, air has been used to remove the heat. The heat is actually blown away. An air cooling system requires an air circulation system with ducts and vents, a fan unit to move the air, and a chiller unit to cool the heated air before it is returned to the circulation.
Another, better way to remove heat is to use a coolant cooling. The process here is also simple. The heat source has a radiator or a component that can be cooled with liquid. Cold liquid is circulated to the heat source and the heated liquid is pumped out and cooled with a water-to-water heat exchanger or a water-to-air cooler. A liquid cooling system requires a piping system, pumping station and a water-water heat exchanger or water-air cooler unit.

Four Advantages Of TKT Battery Pack Cooling System

High efficiency - Actually the specific heat capacity of water is better than that of any other fluid or gas on earth. liquid transfers heat more efficiently because of this.

Save Energy - The difference in the electrical energy consumption isstriking big: the liquid cooling requires less than 10% ofthe electrical energy of the comparable air cooling system!

Small size- Liquids have a better heat capacity than air and can therefore be designed with smaller pipe/element sizes.

Quieter - Liquid cooling is less noisy, allowing for a more comfortable environment.

PD. 10 db increase in noise level practically doubles the amount of noise !
