technical field

Background technique

Current smart terminals usually use a built-in battery. The battery is connected to the main board of the smart terminal through the battery connector. When charging, the output current of the charging chip enters the battery through the battery connector. When discharging, the battery outputs current through the battery connector to supply power to the entire system. At present, it is common to use a battery connector to connect the battery to the main board of the smart terminal. If the battery connector is not fastened, it will cause the situation that the battery cannot be charged and the battery cannot supply power to the system. Currently, for a single battery connector The conventional detection method is to detect whether the charging and discharging pins of the battery are normal. If it is within the normal range, it is considered that the battery is connected normally, otherwise it is considered that the battery is not connected properly.

However, in order to increase the charging power and charging speed of smart terminals, the market has introduced the use of multiple battery connectors at the same time. In cases where multiple battery connectors are used, charging and discharging may be possible even when not all battery connectors are snapped in place, but there will be an impact on the actual charging and discharging effect. Therefore, if the conventional detection method of a single battery connector is used to detect the installation status of multiple battery connectors, it cannot be guaranteed that all the multiple battery connectors are fastened.

The embodiment of the present application can also detect potential looseness of the battery connector in advance by detecting the current difference between the two battery connectors during charging. When the buckle of a battery connector is not fully fastened, the VBATT contact impedance of the unfastened battery connector will increase, and the current allocated to this battery connector will decrease, so that the two batteries are connected to maintain the same differential pressure. When charging with a large current, this situation will cause the advantages of multiple battery connectors to become smaller. When the detected difference exceeds our preset range, it is considered that the battery connector with a relatively small current is potentially loose, which can be Prompt the user in advance to deal with it in a timely manner.

In this case, when the load is heavy, the contact impedance will be large and the voltage drop will be serious due to the virtual connection, which will cause abnormal situations such as slow charging or automatic shutdown when the battery is low. In the embodiment of the application, a hardware circuit can be added, and sampling resistors are connected in series on the paths of multiple battery connectors, so that the current actually transmitted by each battery connector can be sampled. If the current value on a certain path is obviously small, that is If it is less than the preset current, it can be considered that the battery connector is not fastened.
