The embodiment of the invention provides an activation device and method of a battery. The activation device comprises a high-frequency excitation circuit, a battery internal resistance detection circuit, a coupling capacitor and a microprocessor. The coupling capacitor is serially connected between the battery and the high-frequency excitation circuit. The microprocessor is connected with the high-frequency excitation circuit and the battery internal resistance detection circuit. The battery internal resistance detection circuit is connected with the battery. The microprocessor comprises a starting response module used for obtaining a current battery internal resistance value detected by the battery internal resistance detection circuit when receiving a battery starting signal; a comparison module used for comparing the current internal resistance value with a preset standard value; an excitation module used for controlling the high-frequency excitation circuit to send a high-frequency excitation pulse signal to the battery when the internal resistance value is larger than the preset standard value so as to activates the battery. The embodiment of the invention further provides a method for activating the battery through the activation device. The battery activation device and method are safe and reliable and is low in battery consumption.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a battery activation device and method. Background technique [0002] Generally speaking, after a long-term use of the battery or under extreme use conditions such as low temperature conditions, the activity of the internal materials of the battery decreases, and the internal resistance will increase sharply and the polarization will be enhanced, which will cause the output current to become very small or even unusable. Therefore, In order for the battery to work properly, it needs to be activated. [0003] At present, there are mainly two ways to activate the battery. One is to use the external heating device of the battery to forcibly heat the battery to increase the temperature of the battery. temperature. Both of these methods improve the activity of effective materials inside the battery by increasing the internal temperature of the battery. However, these two methods r...
