Battery pack temperature adjusting device

Abstract

The invention discloses a battery pack temperature adjusting device, and aims at solving the problems that a battery pack is poor in charge and discharge performance under the conditions of a high temperature and a low temperature. According to the technical scheme for solving the problem, the battery pack temperature adjusting device mainly comprises the battery pack and a battery box sleeving the outer side of the battery pack, wherein the battery pack is provided with a control circuit and a temperature sensing element; the control circuit is electrically connected with the temperature sensing element; a diversion outlet is arranged in the battery box; a refrigeration piece electrically connected with the control circuit is arranged between the battery pack and the battery box and comprises a positive temperature control surface and a reverse temperature control surface; the positive temperature control surface faces the battery pack; and airflow formed on the positive temperature control surface passes through the battery pack and then flows outside from the diversion outlet. By the battery pack temperature adjusting device, the continuous charge and discharge time of the battery pack is prolonged.

Description

technical field [0001] The invention relates to a battery pack temperature regulating device. Background technique [0002] The battery pack provides electrical energy for the electric equipment to ensure its effective operation, but the discharge and charge rates of the battery pack are different under different working conditions. The internal chemical reaction of the battery cannot be carried out normally due to the influence of temperature, and the discharge efficiency of the battery pack decreases. During the discharge process, the temperature of the battery cell will rise sharply. When it reaches 70°C, the battery pack will start high temperature protection and stop discharging, affecting the normal operation of electric equipment. ; When the battery pack is inserted into the charger and works, when the temperature of the battery pack is lower than 0°C, the battery pack and the charger start low-temperature charging protection, and the battery pack cannot be charged; w...

Problems solved by technology

The above scheme realizes the temperature control of the battery pack in the box within a predetermined temperature range through the semiconductor cooling sheet, but the temperature control of the battery pack in the box is only realized by the temperature exchange of the semiconductor cooling sheet, and the heating and cooling of the battery pack are slow, not It is beneficial for the battery pack to quickly return to the normal temperature range
