- Long service life, requiring 5-10 years;
- Safe and reliable.
Thermal management system
- The thermal management system is equivalent to installing "air
conditioner" for the power battery pack, because the charging and
discharging process of the power battery is actually the process of
chemical reaction. The chemical reaction will release a lot of
heat, which needs to be taken away to keep the power battery within
a reasonable working temperature range, so as to improve the
service life and reliability of the power battery. There are four
main types of thermal management systems: air cooling, water
cooling, liquid cooling and phase change materials. Taking the
water cooling system as an example, the thermal management system
is mainly composed of cooling plate, cooling water pipe, heat
insulation pad and heat conduction pad.
- Because of the internal resistance of the power battery and the
impedance of the electrical connecting parts, the power battery
pack will generate heat under the condition of charge and
discharge. The greater the current, the greater the calorific
value. If the internal heat cannot be dissipated in time, the
service life of the power battery will be affected, resulting in
rapid attenuation of the service life, or the heat will be out of
control, resulting in safety problems. The thermal management
system of power battery pack products is very complex, which needs
to solve the problems of heating, heat dissipation, thermal
insulation, thermal balance and so on.
- The first is the thermal management requirements for the external
environment. In the high latitudes of the northern hemisphere, the
outdoor temperature will reach - 30 ℃ or even lower in winter,
while in the low latitudes, the ground temperature can reach more
than 50 ℃ in summer. Electric vehicles must face the extreme
environmental temperature requirements of cold and heat.
- The current power battery technology can not meet this challenge.
In order to prolong the service life of the power battery and make
the power battery work under such a wide ambient temperature, it is
necessary to install an "air conditioning" system for the power
battery when designing the power battery pack, so that the power
battery can be cooled in summer and heated in winter, So as to
solve the challenge brought by the wide range of ambient
temperature.
