Embodiment 1
[0067] For an example of this application, see figure 1 , a charging management method for multiple battery packs is proposed, including steps S100, S200, S300, S400 and S500.
[0068] S100: Obtain the sampled temperature, sampled voltage and sampled charging current of each battery pack.
[0069] During the charging and discharging process of the battery pack, heat accumulation will occur in the battery pack, causing the temperature of the battery pack to rise. The battery pack has a short time from thermal runaway temperature rise to fire and combustion, which is very prone to fire and cause loss of personnel and property. When the battery pack is always overcharged, the temperature of the battery pack will remain high for a long time, which may cause the battery pack to catch fire.
[0070] In order to overcome the above problems, the voltage measuring element can be used to obtain the battery pack voltage and the temperature sensor can be used to obtain the current batte...
Embodiment 2
[0116] For another embodiment of the application, see Figure 9 , propose another multi-battery pack charging management method. Compared with embodiment 1, the multi-battery pack charging management method proposed in this embodiment also includes step S399 before step S400 in embodiment 1. After adding step S399, step S400 Replaced by steps S401 and S402. Exemplarily, another multi-battery pack charging management method includes the following steps:
[0117] S100: Obtain the sampling temperature, sampling voltage and sampling charging current of each battery pack;
[0118] S200: Determine the target charging current of each battery pack according to the sampled temperature of each battery pack and the sampled voltage of each battery pack;
[0119] S300: Calculate the difference between the sum of the target charging currents of the respective battery packs and the sum of the sampled charging currents of the respective battery packs to obtain a PI total adjustment value; ...
Embodiment 3
[0127] Another embodiment of the present application proposes a multi-battery pack charging management device, please refer to Figure 11 , The multi-battery pack charging management device 10 includes: an acquisition module 11 , a determination module 12 , a calculation module 13 , a sending module 14 and a charging module 15 .
[0128] The acquisition module 11 is used to obtain the sampled temperature, sampled voltage and sampled charging current of each battery pack; the determination module 12 is used to determine the target of each battery pack according to the sampled temperature of each battery pack and the sampled voltage of each battery pack Charging current; calculation module 13, used to calculate the PI total adjustment value according to the target charging current and sampled charging current of each battery pack; sending module 14, used to send the PI total adjustment value to the charging device, so that all The charging device adjusts the total charging curre...
