Problems solved by technology
However, because the traditional fan control can only be simply turned on and off, it cannot automatically control the fan speed according to the temperature to achieve precise temperature control, thus restricting its development.
In order to solve the problem that the traditional fan temperature cannot be controlled automatically, we have developed a fan self-regulating control system to achieve precise temperature control

The invention discloses a storage battery temperature control system for electric automobiles. The storage battery temperature control system comprises a storage battery, a fan, a fan power supply circuit, a starting single chip microcomputer and a fan rotation speed control circuit, wherein the storage battery is used for supplying power to the storage battery temperature control system, the fan is arranged in a storage battery box body, and an input end of the fan is connected with the fan power supply circuit and the fan rotation speed control circuit respectively; the fan power supply circuit comprises a triode, a relay and a plurality of resistors; after a fan starting signal of the starting single chip microcomputer is received the fan power supply circuit, the triode is driven to be put through by a resistor, an RL coil of the relay is communicated with working voltage, a normally-open contact is put through, and then the relay attracts to automatically put through the circuit to supply power to the system; and the fan rotation speed control circuit comprises a plurality of thermistors and a control chip. According to the storage battery temperature control system, the rotation speed of the fan can be automatically adjusted according to the temperature of the storage battery, so that the temperature of the storage battery is stabilized.
Description
technical field [0001] The invention belongs to the technical field of battery temperature control, and in particular relates to a battery temperature control system for electric vehicles. Background technique [0002] Batteries play a key role in fields such as electric vehicle power systems. Therefore, the effective, safe and stable operation of the battery directly affects the performance of the power system. But on the one hand, the working current of the battery is large, which will generate a lot of heat, and on the other hand, the battery pack is in a relatively closed environment, which will lead to a significant increase in the temperature of the battery and a sharp increase in the temperature difference between the battery cells. big. The rise of battery temperature will not only cause danger, but also accelerate the rate of battery life decay. In addition, the increase in the temperature difference between battery cells will cause unbalanced performance of batt...
