Problems solved by technology

However, in this patent case, when a problem occurs in one of the batteries during charging and discharging, the charging switch of the battery cannot be turned off at the same time. Discharge, its load capacity is low and the charging and discharging time is long, which is really a fly in the ointment.

Abstract

The invention relates to a mixed type battery module having a voltage balance unit, which comprises a first battery, a first programmable fuse, a first discharge switch, a first charge switch, a first analog front end circuit, a first heat induction resistor, a second battery, a second programmable fuse, a second discharge switch, a second charge s witch, a second analog front end circuit, a second heat induction resistor, a voltage balance unit and a control. The battery module balances voltage through the voltage balance unit. During charging, in case of accidents, the first charge switch and the second charge switch are turned off concurrently. In case of critical accidents, the first programmable fuse and the second programmable fuse are burnt out concurrently to protect the first battery and the second battery. The invention discloses a charge method of a mixed type battery module having a voltage balance unit and a discharge method of a mixed type battery module having a voltagebalance unit.

Description

technical field [0001] The present invention relates to a hybrid battery module with a voltage balancing unit and its charging and discharging method, in particular to a hybrid battery module with a voltage balancing unit that can discharge the battery pack to achieve the purpose of voltage balancing, and regardless of The battery module is in charging or discharging mode, as long as one battery pack encounters abnormal or critical safety conditions, it will turn off the charging switch, discharge switch or fuse of the two battery packs at the same time to avoid damage to the battery pack. Battery module and charging and discharging method thereof. Background technique [0002] Existing rechargeable battery modules and their charging and discharging methods, for example, US Patent US20050116686 (public patent) discloses a battery device with multiple battery packs, which is mainly used to prevent the degradation of a single (specific) battery, wherein each battery pack Comp...
