Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as Figure 1 ~ Figure 4 The battery pack balance charge and discharge device shown includes a control module, a pack charge and discharge module, a separate discharge module and a display alarm module. The voltage divider circuit in the peripheral circuit of the control module divides the voltage of each battery to the control module. Within the acceptable range, the control module receives the voltage value of each battery and controls the charge and discharge module to charge and discharge the battery according to the received battery voltage. The separate discharge module is connected to each battery. When the battery is charging, the control module controls the separate discharge module. Whether to make the battery enter the discharge state, the control module sends the real-time voltage to the display alarm module and controls the alarm action of the d...

Abstract

The invention provides a battery pack equalizing charging and discharging device in the technical field of charge and discharge. The battery pack equalizing charging and discharging device comprises acontrol module, a group charging and discharging module, an independent discharging module and a display alarm module, wherein a voltage division circuit in a peripheral circuit of the control moduledivides the voltage of each battery into the range acceptable by the control module; the control module receives the voltage value of each battery and controls the charging and discharging module tocharge and discharge the battery according to the received battery voltage; the independent discharging module is connected with all batteries, when the batteries are charged, the control module controls the independent discharging module to enable the batteries to enter a discharging state or not, and the control module sends real-time voltage to the display alarm module and controls the alarm action of the display alarm module. The efficiency of the battery pack is improved, and the service life of the battery pack is prolonged.

Description

technical field [0001] The invention belongs to the technical field of charging and discharging, and in particular relates to a device for equalizing charging and discharging of a battery pack. Background technique [0002] Lithium-ion batteries have the characteristics of high energy density, high internal resistance, high voltage, high cycle times and low self-discharge rate, but they have high requirements for protection circuits. Overcharging and discharging will cause battery life to decrease or even cause battery damage. ,have an accident. At present, lithium-ion batteries have been widely used in electric vehicles. How to prolong the service life of batteries and make electric vehicles safer is an urgent problem to be solved. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a battery pack equalizing charging and discharging device to solve the technical problem that the service life o...
