PRODUCT DESCRIPTION
A High-Voltage Heater Built Around Vertical Space
The EVLINK E Series is a low-profile high voltage coolant heater for electric-vehicle liquid thermal circuits. The supplied technical material lists 20–24 kW rated power, 400–800 V operation, a 370 × 192 × 98 mm envelope and Ø25 mm coolant ports. Its shallow housing is intended to help engineering teams evaluate installation locations where vertical clearance is limited. Thermostat control is specified; no external communication interface is listed. Final selection remains dependent on the released electrical limits, coolant conditions, connector definition, mounting drawing and validation requirements.
SELECTION GUIDE
When the E Series Is the Right Starting Point
The single-model page should help the buyer qualify fit instead of pretending one configuration suits every vehicle.
01
Height-Limited Installation
Start here when the package must fit within the published 98 mm product height.
02
20–24 kW Heating Duty
Match the vehicle heat-load calculation to the released E-Series output range.
03
Broad HV Architecture
Evaluate when the platform operates within the published 400–800 V window.
04
EG Connector Path
Use when the approved vehicle harness can support the released EG/Guoweitong interface.
Review another platform when…
the required heat output falls outside the released E-Series range, the vehicle cannot accept the published footprint, the coolant circuit requires a different port or hose direction, or the approved connector family does not match the E-Series release.

CONTROL & PROTECTION
Integrate the Heater with the Vehicle Control Strategy
The E-series parameter table identifies thermostat control and no communication interface. Confirm the thermostat specification, switching arrangement, power-supply requirements and vehicle control responsibility for the selected configuration.
- Thermostat and vehicle switching review
- Switching, startup and shutdown requirements
- Overvoltage and undervoltage response
- Overcurrent and short-circuit protection
- Overtemperature response and power limiting
INSTALLATION INTERFACES
Freeze the Package Before Vehicle Release
Low height alone does not guarantee installation fit. Check the footprint, brackets, port direction, hose bend radius, cable exit, connector service access and grounding path against the controlled vehicle package.
01
Coolant Path
Confirm Ø25 mm port tolerances, hose direction, flow and pressure limits.
02
Electrical Path
Confirm connector part numbers, mating components, HVIL and pin assignment.
03
Mounting
Confirm hole locations, fasteners, orientation, vibration and service access.
04
Cable Routing
Check high-voltage and low-voltage bend radius and strain relief.
PRODUCT VIEWS
Inspect Ports, Cables and Mounting from Multiple Angles
Use the released 2D or 3D drawing for final packaging; these images support an early visual review.
APPLICATIONS
Where the Low-Profile E Series May Fit
Application suitability is determined by the thermal system and operating conditions, not the vehicle label alone.
01
Light Commercial EVs
Evaluate battery and coolant-loop heating where limited vertical clearance and an 20–24 kW duty align with the vehicle architecture.
02
Electric Buses
Use as a candidate for a defined battery or auxiliary liquid-heating circuit after confirming system load, flow, voltage and installation space.
03
Construction Machinery
Evaluate for high-voltage off-highway coolant circuits after reviewing vibration, contamination, ambient conditions and duty cycle.
EVIDENCE BEFORE RELEASE
Ask for Configuration-Specific Documents
The supplied marketing material references certifications and company capabilities, but supplier qualification should rely on documents that apply to the exact E-Series configuration and project scope.
- Released product specification and 2D / 3D drawing
- Connector and mating-component definition
- Electrical drawing and thermostat specification
- Applicable EMC, ingress, electrical-safety and environmental reports
- Prototype inspection and validation records
- Approved warranty and commercial terms
PROJECT INPUTS
Data Required for E-Series Selection
Providing engineering inputs creates a more useful quotation than requesting a generic price.
- Vehicle and thermal-circuit application
- Minimum / nominal / maximum HV
- Heating duty and heat-up target
- Coolant, flow, inlet/outlet temperature and pressure
- Available envelope, orientation and hose routing
- Electrical connector and thermostat-control requirements
- Validation standards, timing and forecast volume
NEXT STEP
Request an E-Series Configuration Review
Send the vehicle operating window and installation package so the electrical, coolant, connector and control fit can be reviewed together.
For engineering selection and quotation. Final availability and released specifications are project-specific.
FREQUENTLY ASKED QUESTIONS
E Series Technical and Buying Questions
Answers preserve the boundary between supplied marketing material and the released project configuration.
The supplied E-Series material shows a 98 mm product height and positions the heater for installations with limited vertical space. Confirm the complete 370 × 192 × 98 mm envelope, brackets, cable bend radius and service access against the released drawing.
The supplied technical-specification panel lists 20–24 kW rated power. Use the released project datasheet to confirm the orderable rating and operating conditions before quotation.
The supplied technical specification lists a 400–800 V operating range and describes rated voltage as customizable. Confirm nominal, minimum, maximum and transient limits for the exact configuration.
The supplied product display lists Ø25 mm coolant ports, and the source folder identifies an EG/Guoweitong connector configuration. Exact connector part numbers, mating components, pin assignments and coolant-interface tolerances require the released drawings.
The E-series parameter table identifies thermostat control and no communication interface. Confirm protective functions, switching arrangements and any diagnostic provisions against the selected electrical drawing before approval.
The supplied application artwork identifies these vehicle groups. Suitability depends on whether the 20–24 kW duty, voltage window, coolant conditions, installation height, controls and environmental requirements fit the actual vehicle system.
Send vehicle type, minimum/nominal/maximum voltage, heating duty and heat-up target, coolant and flow, inlet/outlet temperatures, pressure limits, installation envelope, preferred connector, thermostat-control requirements, validation scope, timing and forecast volume.
