Introduction
The electric water heater for new energy vehicles is an important heating device specially used for heating and thermal management systems of electric vehicles and hybrid vehicles. It uses electrical energy to heat liquid (usually coolant or antifreeze) and transfers heat to the components or the interior of the vehicle that need to be heated through a circulation system.
Working Principle
The electric water heater heats the liquid through an electric heating element (PTC ceramic element). The heated liquid flows through the heater pipe through a circulating water pump, transferring heat to the heat exchanger (such as a heater) inside the vehicle compartment, thereby achieving heating in the vehicle. In addition, the electric water heater can also be used to preheat the battery pack to improve the performance of the battery in a low temperature environment.
Product application
This product is a liquid heater, specially designed for pure electric buses. PTC coolant heaters rely on on-board power to provide heat for pure electric buses. The rated voltage of the product is 600V and the power is 20KW, which can be adapted to various pure electric bus models. The heating power is strong, providing sufficient and sufficient heat, providing a comfortable driving environment for drivers and passengers, and can also be used as a heat source for battery heating.
This product can be used alone to replace traditional oil-fired liquid heaters to achieve complete energy saving, emission reduction and cost reduction. In extremely cold areas, considering the lack of electricity, it can assist the use of traditional oil-fired liquid heaters. The use method is to connect the pure electric heater and the oil-fired heater in series, and confirm whether it is necessary to increase the water pump according to the actual demand to improve the circulation efficiency.

1. What is a high voltage battery heater?
A high-voltage battery heater is a device used for electric vehicles. It is mainly designed to maintain the high-voltage battery of electric vehicles within a suitable operating temperature range in low-temperature environments. The function of this heater is to increase the temperature of the battery by heating the battery to improve battery performance, battery life and charging efficiency.
2. Why do you need a high voltage battery heater?
Electric vehicle batteries do not perform well in cold weather conditions. To maintain their efficiency, high-voltage battery heaters are vital as they heat the battery to the required operating temperature.
3. How does a high voltage battery heater work?
High voltage battery heaters use a heating element or a series of heating elements to generate heat. This heat is then directed to the battery to warm it up and maintain optimal operating conditions.
4. Are high-voltage battery heaters energy-saving?
Yes, high voltage battery heaters are designed to be energy efficient. They are equipped with an intelligent temperature control system to reduce energy consumption: In low-temperature environments, the battery's conductivity decreases and internal resistance increases, causing battery performance to decrease. Heating the battery can increase the conductivity, reduce the internal resistance, and reduce the energy loss of the battery during charging and discharging, thus improving the vehicle's cruising range.
Improve charging efficiency: In cold conditions, battery charging speed may be limited. By heating the battery, the temperature of the battery can be increased, making it more suitable for receiving electrical energy, improving charging efficiency and reducing charging time.
Extended battery life: High-voltage battery heaters also help mitigate the negative effects of cold on the battery, helping to extend the life of the battery. In extremely cold environments, failure to heat the battery may cause the battery to freeze, adversely affecting the battery's performance and life.
5. Will using a high-voltage battery heater affect battery life?
No, using a high-voltage battery heater will not negatively affect battery life. In fact, it can help extend the life of your battery by ensuring it's operating at optimal temperatures.
6. Are high-voltage battery heaters safe to use?
Yes, high voltage battery heaters are designed with safety features to prevent any accidents or damage. They comply with relevant safety standards and undergo rigorous testing to ensure their reliability.
7. How long does it take for the high-voltage battery heater to preheat the battery?
The time required for battery warm-up depends on many factors such as heater power, battery size, initial temperature of the battery, and ambient temperature. Typically, it takes a few minutes for the battery to reach the desired temperature.
8. Can high voltage battery heaters be used in warm climates?
High voltage battery heaters are primarily designed for use in cold weather conditions. However, some models allow users to have an intelligent temperature control system that automatically monitors and maintains the battery within the optimal temperature range. Such a system would adjust the vehicle's operation based on ambient temperature and battery status to ensure the battery is in optimal condition while minimizing energy consumption.
9. Can high-voltage battery heaters be used in all electric vehicles?
High-voltage battery heaters are typically designed to be compatible with a variety of electric vehicle models. However, it is always recommended to check the specifications of your battery heater to ensure compatibility with your specific vehicle.
