Power device

Abstract

The invention discloses a power device, which comprises a power supply module and a charging module, wherein the power supply module comprises a first to an N-th battery packs which are connected with each other in parallel, cathodes from the first to the N-th battery packs are connected to be used as a power supply cathode of the power device, anodes from the first to the N-th battery packs are connected to be used as power supply anode of the power device, the N is a positive integer which is not smaller than 1, the charging module comprises a charging control circuit group, the charging circuit group comprises N control circuits which are respectively connected with the first to the N battery packs, and are used to respectively control the size of charging current of the first to the N-th battery packs, the output ends of the control circuits, the cathodes and the anodes of the battery packs are respectively connected to form a charging circuit, and input ends of the control circuits are connected with a charging interface of the power device. The power device uses the control circuits in a charging control circuit group to independently changer for each circuit of battery packs, can achieve rapid power supply for each circuit of battery packs, and can improve charging safety.

Description

technical field [0001] The invention relates to the technical field of mobile power supplies, in particular to a power supply device. Background technique [0002] Field operations, such as seismic exploration, are generally carried out in remote areas or mountainous areas with long distances. Many observation points are not only far away from the road, but also the road from the road to the observation point is rugged, requiring manpower to carry instruments and equipment. The size and weight of the equipment has become a real concern of the staff. [0003] Among them, the mobile power supply for various equipment is indispensable in field operations. Various observation instruments need to work continuously for a long time, and a large-capacity mobile power supply is required to ensure their power supply. In field operations, batteries are mostly used as mobile power sources, but the volume and weight of batteries are relatively large (taking 12V, 105AH batteries as an ex...

Problems solved by technology

However, when this type of battery pack is being charged, all the batteries are charged by one charging line of the charger at the same time. Therefore, for a large-capacity battery pack, there are many batteries connected in series or in parallel. If it is charged with a small current, it will take a long time to charge; And if it is charged with a large current, it is easy to cause the battery to heat up, burn out or even explode.
