Description

As electric vehicles (EVs) become more popular, it is important to understand the key components that keep these vehicles running efficiently. Electric vehicle coolant heaters, also known as battery coolant heaters or automotive high-voltage heaters (HVCH), play an important role in maintaining the performance and reliability of electric vehicles.

EV coolant heaters regulate the temperature of the battery pack and high-voltage components of the electric drivetrain. These heaters help ensure the battery is operating within an optimal temperature range, which is critical to maximizing its performance, efficiency and longevity.

Battery performance is directly affected by temperature. Extremely cold temperatures can lead to reduced battery efficiency, range, and overall performance. On the contrary, high temperatures will accelerate the degradation of batteries and shorten their service life. This makes electric vehicle coolant heaters an important component in maintaining battery health in all weather conditions.

In cold climates, electric vehicle coolant heaters play a vital role in pre-conditioning the battery before driving. Coolant heaters help mitigate the effects of cold weather on battery performance by heating the battery to optimal operating temperature. This not only improves driving range but also enhances the overall driving experience for EV owners.

In addition, electric vehicle coolant heaters prevent the battery from overheating in high temperature conditions. By actively cooling the battery pack when necessary, these heaters help protect the battery cells from overheating, thereby extending the overall battery life.

In addition to the battery pack, EV coolant heaters regulate the temperature of high-voltage components in the electric powertrain. These components, including motors, inverters and other electrical systems, must be kept within specific temperature ranges to ensure optimal efficiency and performance. Coolant heaters play a vital role in achieving this goal by actively managing the temperature of these high-voltage components.

It's worth noting that the design and efficiency of EV coolant heaters may vary between EV models. Some vehicles may use a dedicated electric heater, while others may have a coolant heater incorporated into the vehicle's overall thermal management system. Regardless of the specific implementation, the main function remains the same - maintaining the temperature of critical components within the electric vehicle to ensure optimal performance and longevity.

As demand for electric vehicles continues to grow, so does EV coolant heater technology. Manufacturers continue to develop more efficient and reliable coolant heaters to meet the changing needs of electric vehicles. These advancements may include improved heating/cooling capabilities, energy efficiency, and integration with the overall vehicle thermal management system.

In conclusion, the electric vehicle coolant heater is a key component of electric vehicles and plays a vital role in maintaining the temperature of the battery pack and high-voltage components. By ensuring these critical components are operating within optimal temperature ranges, coolant heaters help improve the overall performance, efficiency and longevity of electric vehicles. As the automotive industry continues to embrace vehicle electrification, the importance of EV coolant heaters in supporting the reliability and functionality of electric vehicles cannot be overstated.

Installation example

7KW PTC coolant heater

Vehicle installation environment requirements
A. The heater must be arranged according to recommended requirements, and it must be ensured that the air inside the heater can be discharged with the waterway. If air is trapped inside the heater, it may cause the heater to overheat, thereby activating software protection, which may cause hardware damage in serious cases.
B. The heater is not allowed to be placed at the highest position of the cooling system. It is recommended to place it at a relatively lower position of the cooling system.
C. The working environment temperature of the heater is -40℃~120℃. It is not recommended to install it in an environment without air circulation around high heat sources of the vehicle (hybrid vehicle engines, range extenders, pure electric vehicle heat exhaust pipes, etc.).
D. The permitted layout of the product in the vehicle is as shown in the figure above:

Advantage

A. Overvoltage protection: The entire vehicle needs to have an overvoltage and undervoltage power supply shutdown function
B. Short-circuit current: It is recommended that special fuses be arranged in the high-voltage circuit of the heater to protect the heater and high-voltage circuit related parts.
C. The entire vehicle system needs to ensure a reliable insulation monitoring system and insulation fault handling mechanism.
D. High-voltage wire harness interlock function
E. Ensure that the positive and negative poles of the high-voltage power supply cannot be connected reversely
F: Heater design life is 8,000 hours
