Problems solved by technology

[0002] Most of the starting batteries used in engineering vehicles are used in harsh environments, which are easy to age the batteries. At present, most of the battery starting devices used in diesel generator sets have the disadvantages of short service life, high operating cost, and poor reliability.
One of the reasons is that the battery pack is always in a charging state during the operation of the vehicle. Since the capacities of the multiple batteries (usually two) in the battery pack are usually inconsistent, the voltage of the multiple batteries during the charging process Unbalanced, the battery with small capacity will be overcharged, while the battery with large capacity will be undercharged

Abstract

The invention provides a vehicle battery protection device which comprises a charging protection unit connected with batteries. During the charging process of the batteries, if the voltage of the batteries is greater than or equal to the preset voltage threshold, the electric quantity of the batteries is consumed so as to reduce the voltage of the batteries, and the batteries are prevented from overcharging. The invention also provides a vehicle. Through the technical scheme of the invention, the voltage of a plurality of batteries in a battery pack is equalized, and the batteries can not be damaged due to overcharging. Meanwhile, the under-voltage protection of the battery pack can be realized, and the vehicle can be conveniently restarted after under-voltage.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle battery protection device and a vehicle. Background technique [0002] Most of the starter batteries used in construction vehicles are used in harsh environments, which are easy to age the batteries. At present, most battery starters used in diesel generator sets have the disadvantages of short service life, high operating cost, and poor reliability. One of the reasons is that the battery pack is always in a charging state during the operation of the vehicle. Since the capacities of the multiple batteries (usually two) in the battery pack are usually inconsistent, the voltage of the multiple batteries during the charging process Unbalanced, the battery with small capacity will be overcharged, while the battery with large capacity will not be fully charged. [0003] Therefore, there is a need for a storage battery protection device, which can balance the voltages of mu...
