Battery charging method and system, computer equipment and readable storage medium

Abstract

The invention discloses a battery charging method. The method comprises the steps that: whether a vehicle meets a charging condition or not is judged through a management strategy before charging is started; when the vehicle meets the charging condition, the open-circuit voltage value of the battery is detected, the voltage state of the battery is judged according to the open-circuit voltage valueof the battery, and the voltage state comprises a sufficient-electric-quantity voltage state, a low-electric-quantity voltage state and an over-low-electric-quantity voltage state; when the battery is in a sufficient-electric-quantity voltage state, pulse charging is carried out on the battery through a pulse charging strategy; when the battery is in a low-electric-quantity and low-voltage state,constant-current charging is carried out on the battery through a non-voltage over-low constant-current charging strategy; and when the battery is in an over-low-electric-quantity voltage state, constant-current charging is carried out on the battery through an over-low-voltage constant-current charging strategy. The invention further discloses a battery charging system, computer equipment and areadable storage medium. According to the invention, through a rigorous management strategy, the probability of accidents during battery charging can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of battery charging, in particular to a battery charging method, a battery charging system, computer equipment and a readable storage medium. Background technique [0002] The vehicle-mounted intelligent communication module is an important means to seek help from the outside in case of an emergency. When a driving accident causes a failure of the power supply equipment in the vehicle, the vehicle-mounted intelligent communication module needs to be switched to supply power through the backup battery. The backup battery is generally nickel metal hydride. Battery-based. Therefore, in order to ensure that the on-board intelligent communication module can normally switch to the backup battery for power supply and send a rescue signal when an emergency occurs within the service life of the vehicle, the management strategy for the backup battery is particularly important. [0003] At present, the management stra...

However, this method is easily affected by the temperature of the external environment. If the external environment is locally heated due to air conditioning, heating and other equipment, there will be a deviation between the measured temperature and the actual temperature of the backup battery, and it is easy to mistakenly think that the battery is in high temperature and stop. In case of charging, the charging time of the backup battery is delayed; or the actual temperature of the backup battery has reached a dangerous temperature, but the measured temperature is still within a safe range, which makes the on-board Ni-MH battery continue to charge, and there is a risk of damage to the battery
