Problems solved by technology

There are mainly three methods: first, use relays to continuously switch each battery in the battery pack, so that one battery is detected at each moment. This method has serious shortcomings, such as slow switching speed, and cannot calculate accurate The voltage value, and it is easy to introduce interference, has been eliminated; second, the analog switch is used to gate the voltage channel of the single battery. This method also has certain shortcomings, the circuit is complicated, and the linearity in the small signal range Poor, low precision; Third, use photoelectric isolation devices and large capacitors for sampling and holding, but this circuit also has shortcomings such as long sampling time and low precision

Description

technical field [0001] The invention belongs to the battery monitoring in the process of battery formation in battery production, and also includes applications in automobile batteries, vehicle-mounted terminals on electric vehicles and various storage batteries that need to be monitored, and specifically relates to a wireless battery monitoring terminal. Background technique [0002] At present, batteries are widely used in daily life and national production due to their environmental protection. However, during the application and production process (formation) of the battery, its voltage and temperature often need to be monitored to achieve the purposes of safe use, optimal control, and performance improvement. [0003] Many domestic institutions have begun to study new methods for automatic monitoring of batteries. In battery monitoring, it is mainly aimed at the detection of battery cell voltage, battery pack voltage, current and temperature. At present, people have d...
