The invention provides a lithium battery emergency starting power supply with a low temperature automatic pre-heating function. The lithium battery emergency starting power supply comprises a lithium battery; the electrode of the lithium battery is connected with an output electric clamp; the lithium battery supplies power for external devices via the output electric clamp; a heat source body is arranged outside the lithium battery; the heat source body is connected with the electrode of the lithium battery; the lithium battery supplies power for the heat source body; the heat source body heats up the lithium battery. The heat source body is formed by heating resistance plates which are encapsulated outside the lithium battery and pressed against the surface of the lithium battery. The emergency starting power supply is provided with a heat source body to heat up the lithium battery, automatically heats up the lithium battery under low temperature environment in connection with a control circuit, and ensures that the emergency starting power supply can be used normally under the lower temperature environment.
Description
technical field [0001] The invention relates to an emergency power supply, in particular to a lithium battery emergency starting power supply with a low-temperature automatic preheating function. Background technique [0002] As a representative of new energy, lithium batteries are widely used in many fields. However, due to the inherent characteristics of lithium battery materials, it has very strict requirements on the operating environment temperature. At present, it is difficult to achieve normal high-current start-up and discharge at both high and low temperatures. The actual discharge performance of lithium batteries at low temperatures is far lower than that at room temperature, and it decreases as the temperature drops. Generally, at -20°C, the discharge capacity is only 10% to 20% of that at room temperature, and at -30°C, the discharge capacity is only about 2%. What's more serious is that the starter of a general car requires a larger starting current as the tem...
