摘要
文中对铅酸蓄电池充电数学模型在两阶段充电、恒流放电工作制度下进行了简化,简化后的数学模型是由一个惯性环节1/(T2S+1)和一个一阶微分环节(T1S+1)组成的。惯性环节在充电过程中起主导作用,其时间常数T2的大小决定了充电的快慢,而T2的大小由浓差极化和化学极化内阻R2决定,因此要解决快速充电的问题,就要解决蓄电池的初始极化问题,也就是初始状态问题。
Reducing charge mathematical- model of lead-acid battery in two-stage charge and constant current discharge, reduced mathematical-model is composed of an inertia link and a first order differential link. Inertia link serve the leading function in charging, its time constant T2 size resolve charging speed;whereas, T2 size be governed by internal resistance R2 produced from concentration polarization and chemical polarization; consequently, key to resolve quick charge problem is resolving initial polarization problem Of lead-acid battery,it is initial situation problem.
