Problems solved by technology

[0002] When the traditional charger charges the battery packs grouped in series, the charging voltage is applied at both ends of the battery pack. Since the batteries cannot effectively solve the inconsistency of the batteries in the production and sorting and grouping links, the repeated charging and discharging cycles after the battery grouping Due to factors such as uneven thermal field, the inconsistency between batteries will be enlarged, which will greatly reduce the life of the battery pack.
[0003] In recent years, a technology for independently charging each battery in a battery pack grouped in series has emerged, that is, a one-to-one charging technology in which one battery corresponds to a group of charging outputs (or a charger). The inconsistency of the battery pack has been greatly improved, but because the wiring method of the supporting battery pack has changed greatly compared with the traditional battery pack, it has not been popularized yet.

Embodiment 1

[0056] Embodiment 1, the new charger charges the electric tricycle battery pack of a group of 48V-20AH, as figure 2 Shown:

[0057] The new charger 11 has 2 sets of charging outputs in series, charging outputs 8 and 10 are a set of charging outputs that can automatically identify and charge 12V or 24V batteries (packs), and charging outputs 10 and 9 are a set that can be used for charging 12V or 24V battery (group) for automatic identification and charging output, the two sets of charging output share the output terminal 10;

[0058] The battery pack 12 is composed of four 12V-20AH batteries in series. The charging socket of the traditional battery pack is a three-hole socket, one of which is idle, and a charging wire 15 is added to the wiring method of the traditional battery pack. One end is connected to the positive pole of the 2# battery of the battery pack (it can also be connected to the negative pole of the 3# battery), the other end is connected to the idle position...

Embodiment 2

[0062] Embodiment 2, the new charger charges a group of 36V-12AH electric bicycle battery packs, such as image 3 Shown:

[0063] The new charger 17 has two sets of charging outputs connected in series. The charging outputs 20 and 22 are a set of charging outputs that can automatically identify and charge 12V or 24V batteries (packs). The charging outputs 22 and 21 are a set that can be used for charging. 12V or 24V batteries (groups) are automatically identified and charged with charging output, and the two sets of charging outputs share the output terminal 22;

[0064] The battery pack 18 is composed of two 12V-12AH batteries and one 12V-20AH battery in series, that is, three battery groups with different capacities. The charging socket of the traditional battery pack is a three-hole socket, one of which is idle. A charging wire 25 is added to the wiring method, one end of the charging wire 25 is connected to the positive pole of the 2# battery of the battery pack (it can ...

Embodiment 3

[0068] Embodiment 3, a charging station consisting of two new chargers simultaneously charges a group of 48V-20AH battery packs and a group of 36V-12AH battery packs, such as Figure 4 Shown:

[0069] The charging station 26 is composed of a new charger 27 and a new charger 30. The charging station control circuit 29 can control whether the new chargers 27 and 30 are connected to the power supply by controlling the on-off of the switch 28 and the switch 31, so as to control the charging of the new charger. whether devices 27 and 30 work;

[0070] The new charger 30 is connected to the battery pack 32 through a three-hole plug / socket 35. After the charging station control circuit 29 controls the switch 31 to be connected, the new charger 30 charges the battery pack 32, and the charging station control circuit 29 controls the switch 31 After disconnecting, the new charger 30 stops charging the battery pack 32, and the working principle during charging can refer to Embodiment 1...

Abstract

The invention discloses a novel charger. Two or more groups of charging output ends which are in mutual series connection are provided at the same time, so that a battery pack which is in series connection or in series-parallel connection can be charged; the battery pack which is matched with the charger is provided with a corresponding charging lead wire which is correspondingly connected with the charging output ends of the charger. According to the novel charger, the charging output groups of the novel charger are less than the batteries in the battery pack, that is, at least one group of charging outputs is used for charging the battery pack in a one-to-many manner. According to the novel charger, under the condition that a conventional battery pack is simply improved (for example, only one charging guide wire is added), the effect similar to the one-to-one independent charging technology is achieved, the inconsistency of the batteries is obviously improved, and the service life of the battery pack is prolonged.
