ENGINEERING | EV THERMAL MANAGEMENT

EV Thermal Management Engineering Services

Engineering support for battery thermal management, high-voltage coolant heating, electric compression and intelligent control—from requirements and system architecture to interfaces, prototypes, validation planning and production documentation.

EVLINK works with OEM engineering and purchasing teams to convert vehicle or equipment requirements into a clear, reviewable thermal solution. Final scope and performance depend on the selected product models and verified project inputs.

System

Architecture and sizing

Interface

Mechanical, HV/LV and CAN

Validation

Prototype to production

ENGINEERING BEFORE HARDWARE

Reduce Project Risk Before the Prototype Stage

Professional thermal integration begins with the application requirement—not a catalog model number.

Unclear Thermal Scope

Cooling, heating, cabin, battery, electronics and control ownership are not yet separated.

Component Mismatch Risk

Voltage and headline power alone do not confirm thermal, environmental or interface suitability.

Late Integration Changes

Mounting, connectors, coolant routing and CAN definitions are discovered too late.

Validation Gaps

The prototype is built before operating conditions, acceptance criteria and records are agreed.

ENGINEERING CAPABILITIES

Six Engineering Services Across the Development Cycle

Each service produces practical outputs that your engineering and purchasing teams can review. Scope is confirmed project by project.

Requirements Analysis & Thermal Architecture

Translate platform data and operating conditions into a defined thermal scope, operating modes and interface map.

Product Selection & Sizing

Match BTMS, heater, controller and compressor options to voltage, power, coolant, environment and packaging requirements.

Mechanical & Coolant Integration

Define installation space, mounting, orientation, coolant routing, connections, service access and environmental constraints.

Electrical & High-Voltage Interfaces

Plan HV/LV supply, connectors, wiring responsibilities, protection boundaries and electrical integration inputs.

CAN Communication & Control Logic

Align commands, feedback, operating states, limits, fault handling and diagnostics with the VCU or BMS strategy.

Prototype, Validation & Production Release

Support sample integration, issue review, agreed validation activities, optimization and final documentation preparation.

SYSTEM INTEGRATION

Engineering the Complete Thermal Interface

A product can meet its own specification and still fail at vehicle level if the surrounding interfaces are wrong. EVLINK reviews the component within the complete coolant, refrigerant, electrical and control architecture.

Battery and power-electronics thermal loads
Coolant and refrigerant circuits
High- and low-voltage boundaries
Pumps, valves, sensors and protection
VCU / BMS commands and feedback
Operating modes, faults and diagnostics

DEVELOPMENT WORKFLOW

From Requirement Review to Production Preparation

A gated workflow gives both teams clear inputs, outputs and decisions at every stage.

Requirement Collection

Confirm platform, duty cycle, thermal targets, voltage, environment, interfaces, timing and success criteria.

Concept & Sizing

Develop the preliminary architecture, operating modes, component selection and sizing assumptions.

Interface Definition

Prepare mechanical, coolant, electrical, connector and CAN information for review.

Prototype Delivery

Supply agreed samples and support installation, commissioning and initial issue tracking.

Validation & Optimization

Review agreed test results, investigate issues and update the configuration or control logic.

Production Preparation

Freeze the approved configuration and organize production, quality and delivery documentation.

START WITH RELIABLE DATA

Engineering Inputs Required to Start a Project

Complete project data helps EVLINK identify risks early, avoid unnecessary iterations and prepare a more useful technical proposal.

Vehicle or equipment platform and application
Duty cycle, route, workload or operating profile
Battery capacity, chemistry and thermal data
High- and low-voltage levels
Required cooling and heating power
Ambient and coolant temperature ranges

Installation envelope, mounting and service access
