    • A multi-series battery control system comprises battery cell groups each having a plurality of serially connected battery cells, a plurality of integrated circuits each disposed in correspondence to one of the battery cell groups and a battery control device that exchanges signals with the individual integrated circuits. Each integrated circuit includes an address setting means that receives a message unique to the integrated circuit, different from messages sent to other integrated circuits, from the battery control device, writes over an initialized address of the integrated circuit with the message and alters the message to a message with which an initialized address of another integrated circuit cannot be overwritten in a step assigned with an ordinal number matching the position of the integrated circuit with regard to the connection order.

    • The inventive bi-directional DC-DC converter addresses a problem of an insufficient step-up ratio during the step-up operation that is caused when a turns ratio of the transformer is determined to, for example, match the step-up operation and also address a contrary problem of an insufficient step-down ratio during the step-down operation that is caused when a turns ratio is determined to match the step-up operation. In the inventive bi-directional DC-DC converter that uses a transformer for both step-down and step-up operations, a switching frequency for operating a switching device is set separately for the step-down and step-up operations. For example, when the switching frequency during the step-up operation is lower than the switching frequency during the step-down operation, the range in which the duty ratio in PWM control can be controlled is widened, compensating for step-up ratio insufficiency. Conversely, step-down ratio insufficiency is compensated for by making the switching frequency during the step-down operation lower than the switching frequency during the step-up operation.
    • 本发明的双向DC-DC转换器解决了在升压操作期间由于变压器的匝数比被确定为例如与升压操作相匹配而引起的升压比不足的问题,并且还 解决了当匝数比被确定为与升压操作相匹配时在降压操作期间不足的降压比的相反问题。 在本发明的使用变压器用于降压和升压操作的双向DC-DC转换器中,用于操作开关装置的开关频率分别设置用于降压和升压操作。 例如,当升压操作期间的开关频率低于降压操作期间的开关频率时,可以控制PWM控制中的占空比的范围变大,从而补偿升压比不足。 相反,通过在降压操作期间使开关频率低于升压操作期间的开关频率来补偿降压比不足。
