Embodiment Construction
[0021] The secondary battery detection device with energy-saving charging circuit of the present invention will be further described in detail in conjunction with the accompanying drawings:
[0022] Such as figure 1 Shown: a secondary battery detection device with an energy-saving charging circuit according to the present invention, comprising a secondary battery 1, a charging circuit 2 and a switching power supply 4, the switching power supply 4 charges the secondary battery 1 through the charging circuit 2, and then The voltage at both ends of the secondary battery is detected by the linear optocoupler voltage follower control circuit 3 , and the obtained voltage is fed back to the switching power supply 4 . When it is detected that the voltage across the secondary battery 1 changes, the switching power supply 4 will also change the charging voltage of the secondary battery 1 accordingly.
[0023] Such as figure 2 Shown: Linear optocoupler voltage follower control circuit...

The invention relates to a secondary battery detection device with an energy-saving charging circuit. The device comprises a secondary battery, a charging circuit and a switch power, wherein the switch power charges the secondary battery through the charging circuit, the charging circuit is in parallel connection with a linear opto-coupler voltage-follower control circuit, the output voltage of the switch power is directly decided by voltage at two ends of the battery, and pressure drop on a charging power tube is the minimum voltage to maintain the circuits. When the voltage of the battery is at the low end, extra power loss on the charging power tube does not exist, and an energy-saving effect is achieved. The pressure drop on the charging power tube is little, the charging power tube can be protected, service life is also prolonged, and the device is used for secondary battery detection for a power battery charging circuit.
Description
technical field [0001] The invention relates to the technical field of secondary battery detection devices, in particular to a secondary battery detection device with an energy-saving charging circuit on a power battery. Background technique [0002] At present, with the continuous development of science and technology, the demand for chemical energy is also increasing. As a new energy source, batteries are used in more and more products. The battery is also charged again after discharge, and the cycle is called a secondary battery. Secondary batteries not only have low cost, high recycling rate, and save resources, so the reuse of secondary batteries has been widely valued. At the same time, the detection device of secondary batteries is an indispensable device for charging and discharging secondary batteries. [0003] At present, most of the secondary battery detection devices used, when charging, the charging power supply directly cuts to the highest voltage value, and t...
