Description
HVC High Voltage Coolant Heater for Electric Vehicle
Product Description
HVC high voltage coolant heater can be used for improving battery energy performance in EVs and HEVs. In addition it allows comfortable cabin temperatures to be generated in a short time enabling a better driving and passenger experience. With high thermal power density and fast response time due to their low thermal mass, these heaters also extend pure electric driving range as they use less power from the battery.

Installation Precautions
1.Pay attention to the firm installation before power on, and the reliable connection of the connector.
2. The ground wire is reliably connected to prevent static electricity from damaging components.
3.Antifreeze should not contain impurities to prevent clogging of the water tank.
4. After unpacking, please be sure to check whether there is any appearance damage caused by transportation. Damage caused by improper installation and use (including use and installation conditions beyond the scope specified in the specification) is not covered by the warranty.
Precautions for the use of PTC water heating heaters
The water flow rate in the water cycle is ≥4L/min, if the flow rate is too low, it will cause frequent temperature protection.
Fault phenomenon Fault cause Corrective measures
| Fault phenomenon | Fault cause | Corrective measures |
| Unable to use | The high-voltage connector is not plugged in or poor contact | Check whether the high-voltage connector is in good contact |
| The low-voltage connector is not plugged in or is in poor contact | Check whether the low-voltage connector is in good contact | |
| Decreased insulation resistance | Replace PTC water heating heater | |
| No heating | High voltage connector damaged or poor contact | Check whether the high voltage connector is in good contact |
| The low-voltage connector is damaged or in poor contact | Check whether the low-voltage connector is in good contact | |
| Slow heating | Low water temperature slow startup | None |
| Low high voltage and slow start | Adjust the voltage | |
| Antifreeze flow rate is small | Adjust the flow rate | |
| The waterway is blocked | Clean the waterway |
