Automotive

A holding part that houses the cylindrical cell of an EV battery.
Light weight, flame resistance, and heat resistance are required.

Connectors conforming to automotive OEM standards such as LV214, USCAR, etc., which require high reliability.
Quality and standard requirements for long-term outdoor use, and electrical characteristics capable of withstanding high voltages are required.

An insulating component that separates the cells of an EV battery.
Thin walls, light weight, flame resistance, etc. are required.

An insulated protective cover for the conductor through which high voltage and large current of an EV battery flows.
In addition to requiring electrical tracking ability, flame resistance and heat resistance are also required.

A component that presses and secures the battery cells at both ends of the EV battery module. 
Extremely high strength and rigidity are required to hold the battery cells firmly in place.

Three phase connector to be mounted inside the drive motor.
Ion migration resistance, flame retardance, and tracking resistance are required because of the high power flow, safety, and miniaturization requirements.

High-voltage connectors used around the batteries of electric vehicles.
Orange color is required to alert the user to the high voltage. Flame retardancy and tracking resistance are required.

Battery case for 48V mild hybrid vehicles
An example of combining a design proposal based on plastic CAE simulation and the high mechanical strength of the Leona SG series to pass a drop impact test.

Peripheral parts of fuel cell stacks.
Low elution is required because excess ions can cause trouble in the transfer of electrons in the fuel cell.

Case of nickel-metal hydride (NiMH) batteries for automotive use.
It is required to have electrolyte resistance and to not deteriorate even if it comes in contact with electrodes.
