Abstract

An electrical battery exchanging system for reuse application is disclosed. The system includes: a number of rechargeable battery packs, a battery condition detecting module, a user ID checking module, a power source, a charging controlling module. Since the system can monitor conditions of rechargeable battery cells of the rechargeable battery packs and uses user ID for operating control purpose, it has benefits of conveniently exchanging low-power battery with fully charged one, easily sorting out end-of-life batteries and getting them for recycle or reuse, simply charging service fee and stably operating under a business model.

Claims

1. An electric vehicle battery exchanging system for reuse application, comprising:

a plurality of rechargeable battery packs, each comprising;

a plurality of rechargeable battery cells linked in series or parallel connection; and

a battery cell detecting unit, electrically linked to each rechargeable battery cells, for detecting battery conditions of each rechargeable battery cell and transmitting the battery conditions externally;

a battery condition detecting module, for receiving the battery conditions transmitted from the battery cell detecting unit and sending out a judged command for each rechargeable battery pack based on the battery condition from each rechargeable battery pack to determine if the rechargeable battery pack is allowed to be charged;

a user ID checking module, for communicating with a user ID device which contains a user ID, checking if the user ID is registered in the user ID checking module under a commercial condition, and sending out a confirmed information when the user ID is registered in the user ID checking module under the commercial condition;

a power source, linked to an external power grid, for providing power;

a charging controlling module, electrically linked to the rechargeable battery packs, the battery condition detecting module, the user ID checking module and the power source, for charging the rechargeable battery pack determined by the judged command, processing charging until a predetermined battery status is fulfilled and recording amount of power charged; and

a battery managing module, electrically linked to the user ID checking module and the charging controlling module, for allowing one rechargeable battery pack to be released for use if the predetermined battery status is met and the confirmed information is received or temporarily stored if the predetermined battery status is met but the confirmed information is not received.

2. The electric vehicle battery exchanging system according to claim 1, wherein the battery condition comprises terms of output voltage, state of health (SOH), state of charge (SOC), output current, charging cycle and lifetime.

3. The electric vehicle battery exchanging system according to claim 2, wherein each of the terms has a threshold, and the judged command is not sent to allow the rechargeable battery pack to be charged as long as any value of the terms doesn'"'"'t meet the corresponding threshold.

4. The electric vehicle battery exchanging system according to claim 3, wherein the battery condition detecting module is further for determining which rechargeable battery pack to be repaired for recycling rechargeable battery cells if the threshold of the battery condition of that rechargeable battery pack is not met.
