Custom EV Thermal Management Product Development

Engineering support for application-specific battery thermal management systems, high-voltage coolant heaters, electric compressors and thermal controllers.

EVLINK helps OEM and system-integration teams translate platform requirements into a controlled development scope covering thermal performance, packaging, coolant interfaces, HV/LV connections, CAN communication, prototypes, validation and production release.

Mechanical, HV/LV and CAN

Validation-Gated

Evidence before release

WHEN CUSTOM DEVELOPMENT IS NEEDED

Standard Products Do Not Fit Every Vehicle Platform

Customization should solve a documented technical constraint, not simply create a different part number.

Voltage or Power Mismatch

Existing ratings do not match the platform voltage, thermal load, flow or operating window.

Restricted Installation Space

Envelope, mounting, orientation or service access cannot accept a standard configuration.

Unique Coolant Interfaces

Ports, fluid, flow direction, pressure limits or hose routing require adaptation.

Electrical Interface Changes

HV/LV connectors, wiring, interlock or protection boundaries differ from the base design.

CAN and Control Requirements

Commands, feedback, states, faults or communication timing must align with the vehicle.

Application-Specific Validation

Environment, vibration, duty cycle or approval criteria require a defined test plan.

CHOOSE THE RIGHT DEVELOPMENT ROUTE

Not Every Custom Request Requires a New Product

The first engineering decision is to identify the lowest-risk route that satisfies the platform requirement.

CONFIGURATION

Select an existing platform
and adapt rated options

Lowest development risk

INTERFACE ADAPTATION

Modify package, ports, connectors
or communication interfaces

Controlled engineering change

PLATFORM-SPECIFIC

Develop around unique thermal,
mechanical or control requirements

Requires feasibility and validation

Configurable Product

Start from an existing product platform and select available voltage, power, control or interface options.

Interface Adaptation

Modify selected mechanical, coolant, electrical or communication interfaces around a proven product basis.

Platform-Specific Development

Create a broader product or system variant when the thermal, structural or control requirement cannot be met otherwise.

CUSTOMIZATION SCOPE

Eight Engineering Areas That May Be Customized

The agreed project scope should state exactly what changes, what remains standard and what must be revalidated.

FREQUENTLY ASKED QUESTIONS

Custom EV Thermal Management Development FAQ

What can EVLINK customize for an EV thermal management project?

Depending on feasibility, the scope may include voltage and power, thermal performance, packaging, mounting, coolant ports, HV/LV connectors, CAN communication, operating modes, protection logic, documentation and validation.

Does every custom request require a completely new product?

No. The preferred route is to use a configurable product platform when possible, then consider interface adaptation or platform-specific development only when the technical requirement cannot otherwise be met.

Which products can be developed for project-specific requirements?

Projects may involve battery thermal management systems, high-voltage coolant heaters, electric compressors or integrated thermal controllers, subject to the agreed scope and feasibility review.

What information is needed for a feasibility review?

Provide the application, battery and duty cycle, thermal targets, voltage, power, coolant or refrigerant conditions, installation space, ports, connectors, CAN requirements, environment, standards, timing and expected demand.

Can EVLINK support custom CAN communication?

CAN commands, feedback, states, limits, faults and diagnostics can be reviewed for the selected product and project. The exact software scope must be agreed before development.

How are custom samples validated?

The validation plan should trace agreed requirements to test conditions, measurements and acceptance criteria. The final tests depend on the product, change scope, application and customer requirements.

How long does custom product development take?

Timing depends on requirement completeness, the chosen development route, component availability, tooling, prototype quantity, software work and validation scope. A schedule should be confirmed after feasibility review.

What is required before mass production release?

The approved configuration, drawings, interfaces, software status, validation results, issue closure, quality documents and change-control responsibilities should be confirmed before production release.
