Why is it vital to electrically insulate vehicle battery components ?

 Hybrid electric vehicle insulation is used to shield the vehicle from heating, sound & vibrations, and provide a convenient drive to the passengers. Insulators help in controlling the in-vehicle temperature to obtain a comfortable cabin climate. Overheating in hybrid electric vehicles could majorly impact the battery pack and may lead to degradation of the engine performance. Furthermore, the noise & vibrations develop an adverse ambience inside the vehicle. However, vehicle insulation minimizes the effects through various insulation techniques such as thermal, acoustic and electrical methods. Therefore, evolution in insulators to reduce the noise, heat & vibrations in the vehicles is expected to drive the growth of the global hybrid-electric vehicle insulation market in the near future.

The different components of an electric vehicle battery

In electric vehicles, batteries are made up of three units nested inside one another: cells, modules and the battery pack.

Cells

The cells are at the core of the battery, since they concentrate the substances that will be used to convert chemical energy into electrical energy. They are high-performing, rechargeable accumulators, and are often Lithium-ion, Lithium-ion polymer, or Lithium-metal polymer in type.

Modules

An electric car needs about 1000 times more power than a smartphone. Since the power of a cell is limited, tens or even hundreds or thousands of cells are involved in a battery design. To better protect them and facilitate their replacement in the event of a breakdown, these cells are grouped into different modules.

Battery pack

The battery pack is a gathering of modules together with a cooling system. The battery pack is managed by a safety system called a BMS (Battery Management System), whose function is to control the state of the battery: temperature, voltage, intensity, etc.

Rise in demand for in-vehicle electronic system, stringent regulations imposed for the carbon emission reduction and substantial investments from automakers in electric vehicles drive the growth of the market. However, absence in standardization of charging structure is expected to hamper the growth of the market. On the contrary, scope for further evolution of insulation materials for electric vehicles and scope of growth of autonomous electric vehicles are anticipated to provide lucrative opportunity for the market growth.
