New energy vehicle battery heaters allow the battery to be at the right temperature to keep the entire system of the vehicle running properly. When the temperature is too low, these lithium ions freeze, impeding their own movement and making the battery's power supply capacity drop significantly, so it is necessary to preheat the battery in advance in winter or when the temperature is too low.
New energy pure electric vehicle battery heating system mainly through the following two ways: preheating heating, fuel water heater by installing water heater to new energy electric vehicles, through the transfer of heat to the battery heating has reached the normal working temperature. New energy high voltage electric heater by installing PTC heater to the new energy electric vehicle, which can transmit heat to the electric vehicle battery systemto preheat it and make it at normal working temperature.
In winter, the range of new energy electric vehicles generally shrinks considerably, mainly because the battery pack's electrolyte viscosity rises at low temperatures and the charging and discharging performance of the battery pack decreases. Theoretically: it is forbidden to charge lithium batteries in -20 degrees Celsius (it will cause damage to the battery). Electric vehicles can be solved by installing parking heaters to preheat the battery pack of new energy vehicles so that it is at a normal working temperature, to solve the problem of reduced range of new energy electric vehicles in the low temperature environment in winter and to avoid damage to the battery pack from low temperature charging.
This high voltage coolant heater has improved its heat dissipation rate due to the use of crimped heat sink, and has fully taken into account the various thermal and electrical phenomena of PTC heater parts at work, with its strong bonding, excellent thermal conductivity and heat dissipation performance, high efficiency and reliability. This type of PTC heater has the advantages of small thermal resistance and high heat transfer efficiency, and is an automatic thermostatic, power-saving electric heater.
