REGENERATIVE CURRENT CHARGING CONTROLLER FOR BATTERY IN ELECTRIC AUTOMOBILE

摘要: PROBLEM TO BE SOLVED: To protect a battery against overheating by constitution wherein regenerative charging current control means controls the to be confined with range of heat absorbing stored in memory when temperature exceeds predetermined level due discharging. SOLUTION: A section 3 output from 1 drive motor 2 thus controlling speed an electric automobile. When automobile descends grade, is interlocked rotation wheel operate as generator current. The controller further comprises detecting 4 for 1, 6 determining extent discharging based on ratio time integration initial quantity electricity, and 10 acquiring conditions T 4, 5 6, appropriate reference state decision table 7 data at regulating 8 presenting 3. This protects overheating.
