Embodiment Construction
[0019] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0020] The battery testing device in the prior art generally only uses one control module to control the whole device, and when the control module fails or makes an error, it will inevitably bring great failure and error to the whole battery testing device. In order to solve the above-mentioned technical problems existing in the existing battery testing device, the present invention provides a battery testing device, such as figure 1 As shown, the battery testing device of the first embodiment includes a power module 1, a charging and discharging module 2, a first contro...

The invention provides a battery testing device, which comprises a power source module, a charging-discharging module, a first control module, a second control module, a first switch and a second switch, wherein the power source module is connected with a to-be-tested battery through the charging-discharging module, the first switch and the second switch in sequence; the first control module is connected with the charging-discharging module; the first and the second control modules are both connected with the to-be-tested battery; and the first control module is connected with the second control module. The deficiency of the existing battery testing device that only one control module is adopted to control the whole device, and when the control module fails or makes errors, the safety and the working reliability of the whole battery testing device can be influenced is overcome. Charging-discharging information output by the first control module to the charging-discharging module can be verified by the second control module of the battery testing device provided by the invention, that is, when the charging-discharging information output by the first control module is verified to be identical with the actual charging-discharging information, the charging and the discharging of the to-be-tested battery is controlled, and otherwise the charging and the discharging of to-be-tested battery is not controlled, so that the safety of charging-discharging control of to-be-tested battery is higher.
Description
technical field [0001] The invention belongs to the field of battery testing, and in particular relates to a battery testing device and a testing method thereof. Background technique [0002] Although the battery testing device in the prior art can realize functions such as battery performance testing, battery capacity detection, and battery maintenance, since only one control module is used to control the entire device, when the control module malfunctions or errors, it will give The work of the whole testing device brings unimaginably serious consequences, so the safety and working reliability of the testing device in the prior art are not too high. Contents of the invention [0003] The invention provides a battery testing device with higher safety and better reliability and a testing method thereof in order to solve the technical problems of low safety and working reliability of the battery testing device in the prior art. [0004] Technical scheme of the present inve...
