Problems solved by technology

The lithium battery application industry is an emerging industry. Due to the particularity of lithium batteries, traditional lead-acid battery maintenance equipment technology does not meet the balanced application of lithium batteries. Most of the existing balance maintenance instruments perform low-current charging and discharging of battery modules through the voltage sampling interface. Balanced, does not have high current bidirectional DC-DC control to achieve discharge / charge balance
[0003] Moreover, due to the size and structure of the battery module, when you want to balance the charge and discharge with a large current, you can only use the solution of clamping the copper bar of the battery to perform charge and discharge balance. This solution not only has the risk of short-circuiting the battery due to wrong electrodes , there is also the problem of excessive temperature rise and potential safety hazards due to improper clamp size and unreliable contact.

Abstract

The invention provides a lithium battery module multichannel balanced charging and discharging maintenance testing device which comprises a battery fixing structural member upper cover. The battery fixing structural member upper cover is provided with a plurality of fixing holes and a socket; a plurality of probes are included and the probes are fixedly arranged in the fixing holes; and each probeis connected to the socket. A balanced charging and discharging operation process of the battery module is simple and safe, extra wiring is not needed, extra screws or structural members are not needed to fix the battery module and a test tool, bare-handed operation can be realized without any tool, and the operation is convenient.

Description

technical field [0001] The invention relates to a multi-channel balanced charge and discharge maintenance test device for a lithium battery module. Background technique [0002] With the gradual development of the new energy vehicle industry, the demand for on-board battery maintenance is also increasing. The lithium battery application industry is an emerging industry. Due to the particularity of lithium batteries, traditional lead-acid battery maintenance equipment technology does not meet the balanced application of lithium batteries. Most of the existing balance maintenance instruments charge and discharge battery modules with small currents through the voltage sampling interface. Balanced, does not have high current bidirectional DC-DC control to achieve discharge / charge balance. [0003] Moreover, due to the size and structure of the battery module, when you want to balance the charge and discharge with a large current, you can only use the solution of clamping the ba...
