Abstract

The invention relates to the technical field of lithium batteries, and especially provides an auto-balancing battery tray which includes a tray. A plurality of chambers, which are used for accommodating batteries vertically, are formed in the tray; a positive contact and a negative contact are disposed on the bottom of each chamber. The auto-balancing battery tray also includes a balance controller. The positive contacts are electrically connected to a balance controller positive line bank through a positive connection flat cable. The negative contacts are connected in parallel with a negative parallel connection copper bar and then are connected to a total negative interface of the balance controller. A battery positive/negative detection module is located in the balance controller. By means of the structure, the battery tray can determine the polarity of the batteries; if the polarity of a battery is not conform to demand, the battery tray gives an alarm; in addition, the batteries are connected in parallel, thus achieving balance of the batteries; the battery tray achieves battery polarity detection and battery balance with the electricity in the batteries themselves, so that the battery tray has no consumption except the batteries. The battery tray is used for storing the batteries for a long period.

Description

technical field [0001] The invention relates to the technical field of lithium battery trays, in particular to an automatic balancing battery tray. Background technique [0002] The battery consistency of the battery pack is an important parameter for battery sorting. The existence of inconsistency makes the performance index of the battery pack fail to reach the original level of the single battery, which seriously affects the application of the battery in electric vehicles. The most common phenomenon of differences between the individual cells in the battery pack is that the voltage difference between the battery packs is too large. The large voltage difference is manifested between the batteries connected in series in the battery pack, some of the batteries have a high voltage, and some of the batteries have a low voltage. Because the overcharging and overdischarging of lithium-ion batteries will cause serious damage to the battery, and even fire, explosion and other hid...
