Abstract

This invention relates to a method for controlling charging of storage batteries with gas sensors, which tests oxygen content or gas pressure in the internal gas of the battery with a gas sensor or an outer pressure sensor then uses a differential coefficient method to compute the variety rate of the oxygen or gas pressure to decide its charge state to further determine a charging strategy, which is suitable for Ni-base watercourse batteries.

Description

technical field

[0001] The invention relates to a method for controlling storage battery charging by using a gas sensor, relates to the technical field of batteries, and relates to a control method and device for storage battery charging. Background technique

[0002] The development of batteries for electric vehicles (EV) and hybrid electric vehicles (HEV) has made people pay more attention to high-energy and high-power battery systems. The requirements for battery charging process control are also getting higher and higher. Charging technology has become a part of battery technology. , especially an integral part of batteries in terms of safety, reliability and long-life cycle performance. For batteries used in electric vehicles (EV) and hybrid electric vehicles (HEV), efficient and fast charging capability and judgment of state of charge (SOC) are an important problem to be solved urgently.

[0003] Traditional battery charge control techniques are generally based on pea...
